1. Measures of Center and Variation

Exercise 28 Page 337

Multiply each given measure by 0.5.

Mean: 160
Median: 150
Mode: None
Range: 105
Standard Deviation: 35.3

Practice makes perfect

Consider the given information of a data set.

Mean:320 Median:300 Mode:None Range:210 Standard Deviation:70.6 We are asked to find the values of the measures shown when each value in the data set is multiplied by 0.5. Recalling that when each value of a data set is multiplied by a real number k> 0, the measures of center and variation can be found by multiplying the original measures by k. With this in mind, let's find the new values of each measure shown.

Measure	Original Data Set	* 0.5	New Data Set
Mean	320	320 * 0.5	160
Median	300	300 * 0.5	150
Mode	None	None	None
Range	210	210 * 0.5	105
Standard Deviation	70.6	70.6 * 0.5	35.3
