Validity & Reliability

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

What is the most appropriate way to judge the results of a study?

• Claim that the study is fully Reliable (or valid)

• Claim the study is "High" in reliability (and or validity)

• Claim the study is "High" in reliability (and or validity) and provide supporting reasons for your judgment.

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

A type of internal validity that asks 'Was the research "set up" in a way (the procedures) so that it actually tests or measures what it was “designed” to measure'?

• Cross-cultural Validity

• Construct Validity

• External

• Ecological

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

• True

• False
