Terminology - 2 Psychological Assessment

- A simple graphic of the coordinate points for vales of the X-variable (graph's horizontal axis) and the Y-variable (graph's vertical axis).

• Outlier

• Scatterplot

• The Pearson r

• The spearman rho

Answer explanation

Note:

- Scatterplot are useful because they provide a quick indication of the direction and magnitude of the relationship between two variables.

- Scatterplot are also useful in revealing the presence of curvilinearity.

An eyeball gauge of how curved a graph is.

• Outlier

• Scatterplot

• Curvilinearity

• The spearman rho

Any distinguishable, relatively enduring way in which one individual varies from another.

• Outlier

• Trait

• State

• The spearman rho

A trait is not expected to be manifested in behavior 100% of the time.

• Outlier

• Trait

• State

• Relatively enduring

Psychological traits and states can be quantified and measured.

- Once it's acknowledge that psychological traits and states do exist, the specific traits and states to be measured and quantified need to be carefully defined.

- The test developer has provided test users with a clear operational definition of the construct under study.

• Assumption 1

• Assumption 2

• Assumption 3

• Assumption 5

Answer explanation

Test-related behavior predicts non-test related behavior

- The tasks in some tests mimic the actual behaviors that the test user is trying to understand.

- The obtained sample of behavior is typically used to make predictions about future behavior.

• Assumption 1

• Assumption 2

• Assumption 3

• Assumption 5

Answer explanation

Test and other measurement techniques have strength and weaknesses

- Competent test user understand and appreciate the limitations of the tests they use as well as how those limitations might be compensated for by data from other sources.

• Assumption 4

• Assumption 2

• Assumption 3

• Assumption 5

Answer explanation

Various sources of error are part of the assessment process error

- Refers to factors other than what a test attempts to measure will influence performance on the test.

• Assumption 4

• Assumption 2

• Assumption 3

• Assumption 5

Answer explanation

Component of a test score attributable to sources other than the trait or ability measured.

• Assumption 4

• Error variance

• Assumption 6

• Assumption 5

Answer explanation

All of these is potential sources of Error Variance EXCEPT:

• Assessee

• Measuring instruments

• Reliability

• Assessor
