Answer the following questions about the scatterplot and data:

What type of reliability assessment does this represent?

What conclusions can you draw about the reliability of the test based upon the scatterplot? Why do you draw these conclusions?

Would you say this method of reliability assessment is the best to use to evaluate the reliability of test to design the construct of state anxiety? Why or why not?

A valid instrument is one that measures what it says it measures. Validity depends on the amount and type of evidence there is to support one's interpretations concerning data that has been collected. Content-related, Criterion-related, and Construct-related Evidence.

How would you evaluate the validity of the test described above? Provide a plan to evaluate each type of validity listed below:

Content-related

Criterion-related

Construct-related

Assume the test above correlates with the State-Trait Anxiety Inventory with a correlation coefficient of .20. What type of validity would this correlation represent? What does this correlation show about the validity of the new instrument?
