Reliability and Validity

When a study is said to be "Valid"....

• It is thought to measure what it was supposed to measure

• it is thought that the same or similar results should be achievable if repeated

• The DV is supposed to have the desired impact on the IV

• it is thought to be ineffective

The mos desirable studies are those whose results are thought to be both reliable AND valid

• True

• False

The two general categories of validity are:

• High or Low

• External and Internal

• Ecological, Construct

• Temporal, Cultural

This type of validity refers to how likely the results are able to be applied across different time periods (past, present, future)

• Ecological

• Construct

• Temporal

• Archaic

This type of validity is a judgment about how likely the study was constructed in a way that it reflects real-life situations

• Ecological

• Construct

• Population

• Internal

a measure of whether data can be generalized to other situations outside of the research environment they were originally gathered is called:

• external validity

• internal validity

• ecological validity

• none of the answers are correct

a measure of whether results obtained are solely affected by changes in the variable being manipulated (i.e. by the independent variable) in a cause-and-effect relationship.

• Internal Validity

• External Validity

• Cross-Cultural Validity

• All of the above

It is unlikely for any study to be completely valid and reliable.

• True

• False

Obtaining similar scores for the same group of people form repeatedly using the same instrument over and over is an indication of the instrument's ________.

• Standar Error of Measurement

• Test Norms

• Reliability

• Validity

The type of reliability that is assessed by the test-retest method

• internal

• External
