Find the mean, median, and mode for the data set below. Tell which measure of central tendency best describes the data.
weights of books (oz): 10 15 7 15 14 11
What is the mean
To find the mean, we add up all the values in the data set and divide by the total number of values.
10 + 15 + 7 + 15 + 14 + 11 = 72
There are 6 values in the data set, so we divide 72 by 6:
Mean = 72 / 6 = 12
Therefore, the mean of the data set is 12.
