Problem 1: 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 72Sample B Pulse rates (beats per minute) 65 68 66 72 88 81 94 71 88 91Problem 2: Calculate the mean, median, and mode for each data set.Problem 3: Calculate the sample standard deviation and range of each data set. What is the mean, median, and mode for Sample A and Sample B?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.

Solution Sample A: mean = ΣX/n = 750/10= 75.00 Median=0.5(n+1)th value = 5.5th value of…

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
