Q

Short Answer: Why is reliability important in psychological research?

A

Reliability is important because it ensures that the results of a test are consistent and can be trusted for making inferences about psychological constructs.

Q

Test-retest reliability is just one type of measuring consistency (reliability) of a test. Which of the following are not measures of reliability?

A) Interrater
B) vertical test
C) parallel forms
D) internal consistency

A

B) vertical tests
Vertical tests are category of tests, not a test of reliability. They offer different levels or versions depending on the targeted demographic (ex: age, gender, language, etc.)

Q

A reliability coefficient tells the researcher how much error or variance is in a test. A coefficient of 1.00 indicates no error in the test. Which of the following is NOT true about reliability coefficient?
A) A value of .90 indicates 90% is considered “good” in psychological tests
B) The lower the reliability coefficient the higher the rate of consistency.
C) A coefficient of .80 is considered acceptable for career testing, while a .70 is common for personality tests
D) None of the above are true

A

B)
correct answer: the higher the reliability coefficient, the higher the rate of reliability/ consistency.

B) the 2nd quartile is the median
C) the 3rd quartile lies at the 75th percentile
D) all of the above

A

D) all of the above
Bonus: distance between 25th and 75th percentile is called the interquartile range

Q

In ____ studies, researchers do not manipulate any variables or interfere with the environment. Instead, they simply conduct observations on the same group of subjects over a period of time.

A

longitudinal

17
Q

A ___-___ study design is a type of observational study, or descriptive research, that involves analyzing information about a population at a specific point in time.

A

cross-sectional

18
Q

Examples of this type of research design include case study, naturalistic observation, and surveys.

A

Descriptive research designs

19
Q

In correlational research designs, groups are studied and compared, but researchers cannot introduce variables or manipulate independent variables. Examples include the following:
A) case-control study
B) observational study
C) both A & B
D) neither A or B

A

C) case-control study and observational study

20
Q

In ___ psychology, researchers perform tightly controlled laboratory experiments that eliminate external, erroneous variables. This high level of control allows experimental results to have a high degree of internal validity.

A

experimental

21
Q

T/F
True experiments conducted in a lab may not generalize to the natural environment due to the presence of many external variables

22
Q

___ implies within-person while a ____ analysis implies between-groups or individuals.

A

Ipsative, normative

23
Q

The most popular nonparametric statistical test is the __-___. This is used to determine whether an obtained distribution differs significantly from an expected distribution.

A

chi-square

24
Q

In order to further discriminate between the ANOVA groups post hoc, a researcher will need to use any of of the following measures except?
A) Duncan’s multiple-range test
B) Tukey’s test
C) Scheffe’s test
D) t-test

25
Q

In a ____test the assumption is that the scores are normally distributed. In ___ testing the curve is not a normal distribution.
A) nonparametric; parametric
B) parametric; nonparametric
C) normative; ipsative
D) ipsative; normative

A

parametric; nonparametric

26
Q

All of the following are examples of nonparametric tests except:
A) Solomon and the Krustal-Wallis H-test
B) Wilcoxon signed-rank test for matched pairs
C) Mann-Whitney U test, often just called the U test
D) WAIS-IV

A

D. A, B, and C are all nonparametric tests along with chi-squared *the most common of nonparametric tests

27
Q

____ reasoning goes from specific to a generalization; ____ reasoning goes from general to the specific.

A

Inductive; deductive

28
Q

The ___ ___ predicts what would likely occur if the same individual took the same test again.
A) Standard deviation
B) correlation coefficient
C) Standard error
D) none of the above

A

C) formally known as SEMS - standard error of measurement
