Methods for making predictions or inferences about a population based on a sample.
Hypothesis Testing
A statistical method to evaluate a hypothesis about a population using sample data.
Null Hypothesis
The hypothesis that there is no significant difference or relationship between the variables being studied.
Alternative Hypothesis
The hypothesis that suggests there is a significant difference or relationship between the variables.
ANOVA
Analysis of Variance, a statistical method used to compare means among three or more groups.
Pearson Correlation Coefficient
A measure of the strength and direction of the linear relationship between two continuous variables.
Skewness
The measure of the asymmetry of the probability distribution of a real-valued random variable.
Kurtosis
A statistical measure that describes the distribution of data points in the tails, particularly the peak or flatness.
Item Analysis
A statistical procedure used to evaluate the effectiveness of test items and their contribution to the overall test score.
Test Scores
The results obtained from psychological testing, providing a quantifiable measurement of abilities or traits.
Cumulative Scoring
A method where higher scores indicate higher levels of ability measured by the test.
Ipsative Scoring
A method that compares a test taker's scores on different scales within the same test.
Quantitative vs. Qualitative Measurement
Quantitative refers to measurable numerical data; qualitative describes non-numerical characteristics or qualities.
Dynamic Psychological Assessment
An assessment approach that includes evaluation, intervention, and reevaluation to gauge effectiveness.
Collaborative Psychological Assessment
An assessment method where the client and assessor work together to arrive at a diagnosis.

An evaluative method that involves analyzing a collection of work samples from individuals.
Behavioral Observation
A technique for assessing behavior by systematically observing subjects in specific contexts.
Therapeutic Psychological Assessment
An assessment process that is therapeutic for the client during the evaluation.
Case History Data
Information collected about an individual's past behaviors and circumstances relevant to assessment.
Projective Tests
Tests that use ambiguous stimuli to elicit responses that reveal the subject's personality or unconscious desires.
Error Variance
The amount of error in test score variability that can distort the assessment of true ability.
Nomothetic vs. Idiographic
Nomothetic focuses on general laws and comparisons across groups; idiographic emphasizes individual uniqueness.

Test Norms
Standards that are used to interpret test scores based on the performance of a defined group.
Measurement Error
The difference between the actual score and the observed score due to various factors affecting performance.
Alpha Level
