Validity

The researcher determines the validity by looking at the features of the instrument.

• Construct Validity

• Content Validity

• Face Validity

It measures by subjecting the instrument to an analysis by a group of experts who are knowledgeable about the subject both in theory and practices.

• Construct Validity

• Content Validity

• Face Validity

This refers whether the test corresponds to its theoretical construct.

• Construct Validity

• Content Validity

• Face Validity

It refers to how well the test predicts some future behavior of the examinees .

• Consistency

• Concurrent

• Predictive

The ability of the instrument to measure what it intends to measure.

• Validity

• Reliability

Items sought must be correlated with each other and the test should be internally consistent.

• Internal Consistency

• Test-retest or Stability Test

• Equivalence Test

It is determined by administering both the new test and the standardized test to a group of respondents, then finding the correlation between the two sets of the scores.

• Concurrent

• Predictive

• Consistency

In an experiment, validity would be said to be high if:

• The manipulation of the IV caused the change in the DV

• The manipulation of the DV caused the change in the IV

• Extraneous variables caused the change in the IV

• Construct

• internal

• statistical conclusion

If the design of a research study permits researchers to accurately infer that the independent variable is the cause of the changes observed in the dependent variable, then the design of the study is said to have _____ validity.

• internal

• construct

• statistical conclusion
