Question

choose the correct answer below. a. the mean is the best measure because there are outliers and the data is skewed. b. the mean is the best measure because the data are approximately symmetric. c. the mode is the best measure because the data are at the nominal level of measurement. d. the median is the best measure because the data are skewed. without performing any calculations, determine which measure of central tendency best represents the graphed data. explain your reasoning. heart rates of a sample of adults heart rate (beats per minute) frequency 55 60 65 70 75 80 85 0 10 20 30 40 50

Explanation:

The distribution of heart - rates in the histogram appears to be approximately symmetric. For symmetric data, the mean is the best measure of central tendency as it takes into account all values in the data set.

Answer:

B. The mean is the best measure because the data are approximately symmetric.
