Problem 22

a. use technology to create a scatterplot, to determine the best t line, and to compute r for the entire data set. b. repeat (a), but with the data set obtained by removing the starred (***) data points. c. compare the r-values from (a) and (b), as well as the slopes of the best t lines. Comment on any differences, whether they are substantive, and why this seems reasonable.

Step 1 of 3

Chapter 3: Descriptive Measures Introduction: 3.1 Measures of Center/measures of central tendency (indicates the center of the data set) • Mean o The sum of the observations divided by the number of observations. o Apply to quantitative data Example 01: The following tables provide the weekly salary for employees of two firms (in dollars) Weekly Salaries for Firm1: Weekly Salaries for Firm2: a) Find the mean weekly salary for firm 1 b) Find the mean weekly salary for firm 2 • Median: midpoint of ordered observations. To find the median: Arrange the data in increasing order. • If the number of observations is odd, then the median is the observation exactly in the
