A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matched so that subiects each have systolic and diastolic measurements Find the mean and median for each of the two samples and then compare the two sets of results. Are the measures of center the best statistics to use with these data? What else might be better? Systolic: Diastolic: 96 125 88 145 89 99 146 100 103 117 72 144 1260 58 71 74 51 76 80 86 Are the measures of center the best statistics to use with these data? O A. Since the systolic and diastolic blood pressures measure different characteristics, a comparison of the measures of center doesn't make sense O B. Since the systolic and diastolic blood pressures measure different characteristics, only measures of center should be used to compare the data sets O C. Since the sample sizes are large, measures of center would not be a valid way compare the data sets O D. Since the sample sizes are equal, measures of center are a valid way to compare the data sets. What else might be better? O A. Since measures of center are appropriate, there would not be any better statistic to use in comparing the data sets O B. Because the data are matched, it would make more sense to investigate whether there is an association or correlation between the two blood pressures O C. Because the data are matched, it would make more sense to investigate any outliers that do not fit the pattern of the other observations O D. Since measures of center would not be appropriate, it would make more sense to talk about the minimum and maximum values for each data set
