Answer to Question 1

ANS: D
The researcher needs to obtain as complete a picture of the sample as possible.
Frequencies of descriptive variables related to the sample are usually obtained first.
Validity is not determined by descriptive statistics.
Descriptive statistics would not indicate reliability.
Descriptive statistics are not powerful analysis measures.

Deviants and outliers are not the same.
Unexpected findings can occur with or without outliers.
Subjects can be grouped into categories or not, the process may highlight outliers, but would not define them.
