Assessment Flashcards
Which type of reliability assesses the consistency of results across different forms of a test?
Alternate forms reliability
Fill in the blank: _______ reliability refers to the consistency of a test over time.
Test-retest
What does internal consistency reliability measure?
It measures whether different items on a test that are supposed to measure the same construct yield similar results.
Which statistical method is commonly used to assess internal consistency?
Cronbach’s alpha
True or False: High reliability guarantees that a test is valid.
False
What is inter-rater reliability?
It is the degree to which different raters or observers give consistent estimates of the same phenomenon.
Which of the following is NOT a type of reliability? A) Test-retest B) Internal consistency C) Validity D) Alternate forms
C) Validity
Short Answer: Why is reliability important in psychological research?
Reliability is important because it ensures that the results of a test are consistent and can be trusted for making inferences about psychological constructs.
Which of the following are key purposes of correlation?
A) Prediction about relationship between variables
B) Concurrent validity
C) Reliability
D) all of the above
D) prediction, concurrent validity, and relaiability
This measure often noted as (r) indicates the extent to which the pairs of numbers for a set of variables lie on a straight line.
A) reliability
B) t-test
C) parallel forms
D) correlation coefficient
D) Correlation coefficient
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
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.)
T/F
A reliable test is always valid
F
a valid test is ALWAYS reliable
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
B)
correct answer: the higher the reliability coefficient, the higher the rate of reliability/ consistency.
T/F
Statistical regression predicts that very high and very low scores will move toward the mean if the test is administered again.
T
Quartile refers to the points that divide the a distribution into fourths. This indicates
A) the 25th percentile is in the 1st quartile
B) the 2nd quartile is the median
C) the 3rd quartile lies at the 75th percentile
D) all of the above
D) all of the above
Bonus: distance between 25th and 75th percentile is called the interquartile range
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.
longitudinal
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.
cross-sectional
Examples of this type of research design include case study, naturalistic observation, and surveys.
Descriptive research designs
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
C) case-control study and observational study
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.
experimental
T/F
True experiments conducted in a lab may not generalize to the natural environment due to the presence of many external variables
T
___ implies within-person while a ____ analysis implies between-groups or individuals.
Ipsative, normative
The most popular nonparametric statistical test is the __-___. This is used to determine whether an obtained distribution differs significantly from an expected distribution.
chi-square
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
D) t test
