Answer to Question 1

ANS: A

Feedback
A Inferential statistics are used by researchers to make predictions and generalize findings on the basis of data.
B Descriptive statistics are used to describe and summarize data by reducing data to manageable proportions by summarizing them.
C Nonparametric statistics are a type of inferential statistics.
D The term mathematical statistics is a circular answer.

Answer to Question 2

ANS: A, D

Feedback
Correct Random error is attributable to transient subject states, study context, or administration of the instrument.
Bias in subject behavior and incorrect instrument calibrations are causes of systematic error.
Incorrect Variance and error are connected as a research term, error variance, which is defined as variability in test scores.
Persistent error is not a research term.
