Question 82

765

Using the data in question 764 one could say that a person with an IQ score of 122 would fall within _______.

A. + or -1 SD of the mean
B. the average IQ range
C. an IQ score which is more than 2 SD above the mean.
D. + or -2 SD of the mean

Pg. 450

Answer 82

D. + or -2 SD of the mean

The greater the SD, the greater the spread.

Question 83

766

The standard deviation (SD) is the square root of the variance. A z-score of +1 would be the same as ______.

A. 1 SD above the mean
B. 1 SD below the mean
C. the same as a so-called t-score
D. the median score if the population is normal

Pg. 450

Answer 83

A. 1 SD above the mean

Z-scores are the same as standard deviations (SDs)!!!

Question 84

767

Z-scores (also called standard scores) are the same as standard deviations, thus a z-score of -2.5 means ______.

A. 2.5 SD below the mean
B. 2.5 SD above the mean
C. a CEEB score of 500.
D. -.05% of the population falls within this area of the curve

Pg. 451

Answer 84

A. 2.5 SD below the mean

A CEEB score is also referred to as an ETS score. This was created to eliminate negative scores.

Question 85

768

A t-score is different from a z-score. A z-score is the same as the SD. A t-score, however, has a mean of 50 with every 10 points landing at a SD above or below the mean. Thus a t-score of 60 would equal +1 SD while a t-score of 40 would be _______.

A. -2 SD
B. -1 SD
C. a z-score of +2
D. a z-score of +1

Pg. 451

Answer 85

B. -1 SD

Question 86

769

An IQ score on an IQ test which was 3 SD above the mean would be _______.

A. about average
B. slightly below the norm for adults
C. approximately 110
D. very superior

Pg. 452

Answer 86

D. very superior

Question 87

770

A platykurtic distribution would look approximately like _______.

A. the upper half of a bowling ball.
B. the normal distribution.
C. the upper half of a hot dog, lying on its side over the abscissa.
D. a camel’s back.

Pg. 452

Answer 87

C. the upper half of a hot dog, lying on its side over the abscissa.

kurtosis = peakedness of a frequency distribution

platykurtic = curve is flatter & more spread out than a normal curve (plat sounds like flat)

leptokurtic = curve is very tell, thin, and peaked (leaps tall buildings)

Question 88

771

Test scores on an exam that fell below 3 SD of the mean or above 3SD of the mean could be described as _______.

A. extreme
B. very typical or within the average range
C. close to the mean
D. very low scores

Pg. 453

Answer 88

A. extreme

Question 89

772

In World War II the Air Force used stanine scores as a measurement. Stanine scores divide the distribution into nine equal intervals with stanine 1 as the lowest ninth and 9 as the highest ninth. In this system 5 is the mean. Thus a Binet IQ score of 101 would fall in stanine ______.

A. 1
B. 9
C. 5
D. 7

Pg. 453

Answer 89

C. 5

Stanine = standard & nine

The mean or average score on the Binet is 100, so a score of 101 would fall in stanine 5.

Question 90

773

There are four basic measurement scales: the nominal, the ordinal, the interval, and the ratio. The nominal scale is strictly a qualitative scale. It is the simplest type of scale. It is used to distinguish logically separated groups. Which of the following illustrates the function of the nominal scale?

A. a horse categorized as a second-place winner in a show.
B. a DSM or ICD diagnostic category.
C. an IQ score of 111
D. the weight of an Olympic barbell set

Pg. 453

Answer 90

B. a DSM or ICD diagnostic category.

NOIR
N = nominal
O = ordinal 
I = interval 
R = ratio 

parametic tests = interval & ratio
nonparametic tests = nominal & ordinal

Nominal scales merely classify, names, labels, or identifies by group

A nominal scale has not tru zero point & does not indicate order. (ex: street address, phone number, etc.)

Question 91

774

The ordinal scale rank orders variables, though the relative distance between the elements is not always equal. An example of this would be _______.

A. a horse categorized as a second-place winner in a race.
B. an IQ score of 111.
C. the weight of an Olympic barbell set.
D. a temperature of 78 degrees Fahrenheit.

Pg. 454

Answer 91

A. a horse categorized as a second-place winner in a race.

NOIR
N = nominal
O = ordinal 
I = interval 
R = ratio 

parametic tests = interval & ratio
nonparametic tests = nominal & ordinal

Ordinal scale provides relative placement or standing but does not delineate absolute differences.

Adding, subtracting, multiplying, or dividing is a no-no

Ordinal = order

Question 92

775

The interval scale has numbers scaled at equal distances but has no absolute zero point. Most tests used in school fall into this category. You can add and subtract using interval scales but cannot multiply or divide. An example of this would be that _______.

A. an IQ of 70 is 70 points below an IQ of 140, yet a counselor could not assert that a client with an IQ of 140 is twice as intelligent as a client with an IQ of 70.
B. a 20 lb weight is half as heavy as a 40 lb weight.
C. a first-place runner in three times as fast as the third-place finisher.
D. a baseball player with number 9 on his uniform can get 9 times more hits than player number 1.

Pg. 455

Answer 92

A. an IQ of 70 is 70 points below an IQ of 140, yet a counselor could not assert that a client with an IQ of 140 is twice as intelligent as a client with an IQ of 70.

NOIR
N = nominal
O = ordinal 
I = interval 
R = ratio 

parametic tests = interval & ratio
nonparametic tests = nominal & ordinal

IQ tests provide interval measurement!!!

Question 93

776

A ratio scale is an interval scale with a true zero point. Ratio measurements are possible using this scale. Addition, subtraction, multiplication, and division all can be utilized on a ratio scale. In terms of counseling research _________.

A. the ratio scale is the most practical.
B. all true studies utilize the ratio scale.
C. A & B
D. most psychological attributes cannot be measured on a ratio scale.

Pg. 455

Answer 93

D. most psychological attributes cannot be measured on a ratio scale.

NOIR
N = nominal
O = ordinal 
I = interval 
R = ratio 

parametic tests = interval & ratio
nonparametic tests = nominal & ordinal

ratio scale = highest level of measurement (time, height, weight, temperature, on the Kelvin scale, volume, and distance can all be scaled on a ratio scale).

Question 94

777

Researchers often utilize naturalistic observation when doing ethological investigations or studying children’s behavior. In this approach _______.

A. the researcher manipulates the IV.
B. the researcher manipulates the IV and the DV.
C. the researcher does not manipulate or control variables.
D. the researcher will rely on a 2 x 3 factorial design.

Pg. 456

Answer 94

C. the researcher does not manipulate or control variables.

When utilizing naturalistic observation the researcher does not intervene.

Question 95

778

The simplest form of descriptive research is the ______ which requires a questionnaire return or completion rate of ______ to be accurate.

A. survey; 5%
B. survey; 10-25%
C. survey; 50-75%
D. survey; 95%

Pg. 456

Answer 95

C. survey; 50-75%

Survey problems include:

• poor construction of the instrument
• low return rate
• oftentimes, subjects are not picked at random, thus are not representative of the population

Question 96

779

A researcher gives a depressed patient a sugar pill and the individual’s depression begins to lift. This is known as ______.

A. the Hawthorne effect
B. the Halo effect
C. the placebo affect
D. the learned helplessness syndrome

Pg. 457

Answer 96

C. the placebo affect

nocebo = has a negative effect (ex: when a doctor comments that a person with some condition has only 6 months to live)

Question 97

780

A. the Hawthorne effect
B. the Halo effect
C. the Rosenthal effect
D. a Type II error in the research

Pg. 457

Answer 97

A. the Hawthorne effect

“reactive effect” or “reactivity” = subjects’ behavior is influenced by the very presence of the researcher

This is sometimes known as an “observer effect”

Question 98

781

An elementary school counselor tells the third-grade teacher that a test revealed that certain children will excel during the school year. In reality, no such test was administered. Moreover, the children were unaware of the experiment. By the end of the year, all of the children who were supposed to excel did excel! This would best be explained via ________.

A. the Hawthorne effect
B. the Halo effect
C. the Rosenthal effect or the experimenter expectancy effect
D. observer bias

Pg. 458

Answer 98

C. the Rosenthal effect or the experimenter expectancy effect

Question 99

782

A panel of investigators discovered that a researcher who completed a major study had unconsciously rated attractive females as better counselors. This is an example of ________.

A. the Hawthorne effect
B. the Halo effect
C. the Rosenthal effect
D. trend analysis

Pg. 459

Answer 99

B. the Halo effect

Halo effect = occurs when a trait which is not being evaluated influences a researcher’s rating on another trait

Trend analysis = statistical procedure performed at different times to see if a trend is evident

783

All of the following describe the analysis of covariance technique EXCEPT:

A. It is a correlation coefficient.
B. It controls for sample differences which exist.
C. It helps to remove confounding, extraneous variables.
D. It statistically eliminates differences in average values influenced by covariates.

Pg. 459

Answer 100

A. It is a correlation coefficient.

Question 101

784

Three years ago an inpatient addiction treatment center in a hospital asked their clients if they would like to undergo an archaic form of therapy created by Wilhelm Reich known as “vegotherapy”. Approximately half of the clients stated that they would stick with the tried-and-true program of the center. Outcome data on their drinking was compiled at the end of seven weeks. Today - three years later - a statistician compared the two groups based on their drinking behavior at the end of the seven weeks using a t test. This study could best be described as _________.

A. correlation reseach
B. a true experiment
C. a cohort study
D. casual comparative research

Pg. 461

Answer 101

D. casual comparative research

Since the groups were not randomly assigned and the current researcher did not truly control the IV in the study (since it took place 3 years ago) “d” is the best answer

Question 102

785

The WAIS-IV IQ test is given to 100 adults picked randomly. How many of the adults most likely would receive an IQ score between 85 and 115?

A. 7
B. 99
C. 95
D. 68

Pg. 461

Answer 102

D. 68

in a normal distribution approximately 68% of the population will fall between +/-1 SD of the mean

one SD on most popular IQ tests is 15 or 16, and the mean score is generally 100

Choice “c” is indicative of +/-2 SD, & choice “b” is indicative of +/-3 SD

Question 103

786

A researcher creates a new motoric test in which clients throw a baseball at a target 40 feet away. Each client is given 100 throws, and the mean on the test is 50 (in other words, out of 100 throws the mean number of times the client will hit the target is 50 times). Sam took the test and hit the target just two times out of the 100 throws allowed. Jeff, on the other hand, hit the target an amazing 92 times out of 100 tries. Using the concept of statistical regression toward the mean the research would predict that _____________.

A. Sam’s and Jeff’s scores will stay about the same if they take the test again.
B. Sam and Jeff will both score over 95 next time.
C. Sam’s score will increase while Jeff’s will go down.
D. Sam will beat Jeff if they both are tested again.

Pg. 462

Answer 103

C. Sam’s score will increase while Jeff’s will go down.

Statistical regression predicts that very high and very low scores will move toward the mean if a test is administered again.

Quartile = refers to points that divide a distribution into fourths

25th percentile = first quartile
second quartile = median
75th percentile = third quartile

interquartile range = the score distance between the 25th percentile and the 75th

787

Standardized tests always have _______.

A. formal procedures for test administration and scoring
B. a mean of 100 and an SD of 15
C. a mean of 100 and a standard error of measurement of 3
D. a reliability coefficient of +.90 or above

Standardization = testing format, test materials, and scoring process is all consistent

Question 105

788

There are two distinct types of developmental studies. In a cross-sectional study, clients are assessed at one point in time. In a longitudinal study, however, _______.

A. the researcher has an accomplice pose as a client and act in a certain manner.
B. the same people are studied over a period of time.
C. the researcher relies on a single observation of a variable being investigated.
D. all of the above.

Pg. 463

Answer 105

B. the same people are studied over a period of time.

cross-sectional study = synchronic method
Longitudinal study = diachronic method

Longitudinal study:

1. age itself can be used as an IV
2. data are collected at different points in time

Cross-sectional study:
1. data are indicative of measurements or observations at a single point in time (this method is preferable in terms of time consumption)

“confederate” or “stooge” = a researchers accomplice who poses as a client and acts in a certain manner. (common with social psychology studies)

Question 106

789

A counselor educator, Dr. Y, is doing research on his classes. He hypothesizes that if he reinforces students in his morning class by smiling each time a student asks a relevant question, then more students will ask questions and exam grades will go up. Betty and Linda accidentally overhear Dr. Y discussing the experiment with the department chair. Betty is a real people pleaser and decides that she will ask lots of questions and try to help Dr. y confirm his hypothesis. Linda, nevertheless, is angry that she is being experimented on and promises Betty that Dr. Y could smile until the cows came in but she still wouldn’t ask a question. Both Linda and Betty exemplify ________.

A. internal versus external validity.
B. ipsative versus normative interpretation of test scores.
C. the use of the nonparametric chi-square test.
D. demand characteristics of experiments.

Pg. 464

Answer 106

D. demand characteristics of experiments.

Ipsative = a within-person analysis rather than a normative analysis between individuals (ex: was your jog faster today than it was yesterday?)

Chi-square = most popular nonparametric statistical test. Used to determine whether an obtained distribution differs significantly from an expected distribution

Demand characteristics = any knowledge that a subject may have that can influence their behavior. Can confound an experiment.

Question 107

790

If an ANOVA yields a significant F value, you could rely on _______ to test significant differences between group means.

A. one- and two-tailed t tests
B. percentile rank
C. Duncan’s multiple-range, Tukey’s, or Scheffe’s test
D. summative or formative evaluation

Pg. 465

Answer 107

C. Duncan’s multiple-range, Tukey’s, or Scheffe’s test

Question 108

791

Switching the order in which stimuli are presented to a subject in a study is known as _______.

A. the Pygmalion effect
B. counterbalancing
C. ahistoric therapy
D. multiple treatment interference

Pg. 466

Answer 108

B. counterbalancing

the Pygmalion effect = Rosenthal/Experimenter effect

Question 109

792

A doctoral student who begins working on his bibliography for his thesis would most likely utilize _______.

A. SPSS
B. ERIC, for primary and secondary resources
C. O*NET
D. a random number table or random number-generation computer program

Pg. 466

Answer 109

B. ERIC, for primary and secondary resources

ERIC = Educational Resources Information Center (bank of scholarly literature and resources)

SPSS = Statistical Package Social Sciences (popular computer software program that computes statistics)

Question 110

793

In a random sample each individual in the population has an equal chance of being selected. Selection is by chance. In a new study, however, it will be important to include 20% African Americans. What type of sampling procedure will be necessary?

A. standard (i.e., simple) random sampling
B. cluster sampling
C. stratified sampling
D. horizontal sampling

Pg. 467

Answer 110

C. stratified sampling

Quota sampling = a type of stratified sampling

standard random sampling = sticking hand in fish bowl to draw name

cluster sampling = uses an existing sample/cluster of people or selects a portion of the overall sample

horizontal sampling = subjects are from a SINGLE socioeconomic group

vertical sampling = subjects are from TWO OR MORE socioeconomic groups

snowball sampling/chain referral = uses subjects to bring in other subjects for the study

Question 111

794

A researcher wants to run a true experiment but insists she will not use a random sample. You could safely say that ______.

A. she absolutely, positively cannot run a true experiment.
B. her research will absolutely, positively be casual comparative research.
C. she could accomplish this using systematic sampling.
D. her research will be correlational.

Pg. 468

Answer 111

C. she could accomplish this using systematic sampling.

Today it is more common for researchers to use systematic sampling, since it is often easier.

10,000 people, you want 1,000 for study, you include every 10th person

systemic sampling = depending on the number of interested persons (the higher the number the more it is like random) , it is much like random sampling

Question 112

795

An operational definition _______.

A. outlines a procedure
B. is theoretical
C. outlines a construct
D. is synonymous with the word axiom

A. Mann-Whitney U test, often just called the U test.
B. Wilcoxon signed-rank test for matched pairs.
C. Soloman and the Kruskal-Wallis H test.
D. All of the above are nonparametric measures.

Pg. 470

Answer 113

D. All of the above are nonparametric measures.

Question 114

797

A researcher studies a single session of counseling in which a counselor treats a client’s phobia using a paradoxical strategy. He then writes in his research report that paradox is the treatment of choice for phobics. This is an example of ________.

A. deductive logic or reasoning
B. inductive logic or reasoning
C. attrition or so-called experimental mortality
D. construct validity

Pg. 471

Answer 114

B. inductive logic or reasoning

inductive = goes from specific to generalization

deductive = if many subjects are observed being cured

attrition or so-called experimental mortality = when subjects drop out of a study

Question 115

798

A. deductive logic
B. inductive logic
C. an empathic assertion
D. an I statement

Pg. 472

Answer 115

A. deductive logic

Here the client assumes that the general can be reduced.
