Question
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 subjects 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:
Find the means.

Compare the results. Choose the correct answer below.
Are the measures of center the best statistics to use with these data?
mm Hg.
A. The mean and the median for the systolic pressure are both lower than the mean and the median for the diastolic pressure.
B. The median is lower for the diastolic pressure, but the mean is lower for the systolic pressure.
C. The mean and the median for the diastolic pressure are both lower than the mean and the median for the systolic pressure.
D. The mean and median appear to be roughly the same for both types of blood pressure.
E. The mean is lower for the diastolic pressure, but the median is lower for the systolic pressure.
A. Since the sample sizes are large, measures of center would not be a valid way to compare the data sets.
B. Since the sample sizes are equal, measures of center are a valid way to compare the data sets.
C. Since the systolic and diastolic blood pressures measure different characteristics, a comparison of the measures of center doesn't make sense.
D. Since the systolic and diastolic blood pressures measure different characteristics, only measures of center should be used to compare the data sets.
What else might be better?
A. Because the data are matched, it would make more sense to investigate whether there is an association or correlation between the two blood pressures.
B. 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.
C. Since measures of center are appropriate, there would not be any better statistic to use in comparing the data sets.
D. Because the data are matched, it would make more sense to investigate any outliers that do not fit the pattern of the other observations.
