Answer to Question 1

ANS: B
The Pearson product moment correlation is represented by the r correlation coefficient statistic
The F statistic is a calculated value that determines significance in data analysis.
The t test uses the standard deviation of the sample to estimate the standard error of the sampling distribution.
X2 is the symbol for the Chi-square statistic.

Answer to Question 2

ANS: C
Scatterplots can be used to illustrate the relationship of scores on one variable with scores on another.
The box-and-whiskers plot is used for exploratory data analysis.
The Q-plot is an exploratory data analysis technique that displays the scores or data in a distribution by quantile.
A stem-and-leaf display presents scores visually to obtain insight.
