Home library pages data set. Book1/ 27, book2/ 20, book 3/ 35, book 4/19, book5/ 27, book6/ 30, book7/ 19, book8/ 26, book9/ 32, book10/ 23, book11/ 15, book12/ 28, book13/ 31, book14/ 19, book15/ 24, find the mean, median, mode, and range. Show work for each. Create a graph.
Mean: To find the mean, we add up all the values and divide by the total number of values.
(27 + 20 + 35 + 19 + 27 + 30 + 19 + 26 + 32 + 23 + 15 + 28 + 31 + 19 + 24) / 15 = 24.4
So the mean is 24.4.
Median: To find the median, we need to put the values in order from smallest to largest and find the middle value. If there are two middle values, we take the average of the two.
15, 19, 19, 19, 20, 23, 24, 26, 27, 27, 28, 30, 31, 32, 35
There are 15 values, so the median is the 8th value, which is 26.
Mode: The mode is the value that appears most frequently.
The mode is 19, as it appears three times.
Range: To find the range, we subtract the smallest value from the largest value.
35 - 15 = 20
So the range is 20.
