Question 1 Get help formatting numbers and formulas Consider the following two samples: Sample 1: 15, 13, 11, 8, 11, 5, 15, 5 Sample 2: 15, 5, 15, 5, 11, 15, 11, 5 (a) Calculate the sample range for both samples. Would you conclude that both samples exhibit the same variability? Sample 1 Range Sample 2 Range- So, both samples the same variability when using the sample range as the measure of dispersion (b) Calculate to 3 decimal places the sample standard deviations for both samples. Do these quantities indicate that both samples have the same variability? Sample 1 standard deviation = Sample 2 standard deviation = So, both samples the same variability when using the sample standard deviation as the measure of dispersion Statistical Tables and Charts

Explanation / Answer

Descriptive Statistics: sample1

Variable      StDev     Range
sample1      4.03    10.00

Descriptive Statistics: sample2

Variable     StDev    Range
sample2      4.65    10.00

Both the samples have the same variability when using the sample range as a measure of dispersion.

But both the samples doesnot have same variability when using the sample standard deviation as a measure of dispersion. Sample 1 has less variability since s.d value is low.
