 You are given pulse rates for two sample distributions. Describe the data in terms of central tendency and variability.

Sample A Pulse rates (beats per minute) 66 75 72 69 78 73 82 79 84 72

Sample B Pulse rates (beats per minute) 65 68 66 72 88 81 94 71 88 91

 Calculate the mean, median, and mode for each data set.

 Calculate the sample standard deviation and range of each data set.

• Which might be the better measure for central tendency and why? When answering this question, think about which measure will give you the best representative score of the data.


• What is the standard deviation of Sample A and Sample B?


• How variable are the data? When answering this question, compare the range of Sample A and Sample B.


• Suppose you know your pulse-rate is 74 beats per minute. Would this seem to be slower or faster than the two samples? Explain your reasoning
