To find the mean, we add up all the values and divide by the number of values:
(17 + 20 + 35 + 19 + 27 + 30 + 19 + 26 + 32 + 23 + 15 + 28 + 31 + 19 + 24) / 15 = 25
So the mean is 25.
To find the median, we need to find the middle value. First, we need to put the values in order:
15, 17, 19, 19, 19, 20, 23, 24, 26, 27, 28, 30, 31, 32, 35
There are 15 values, so the median is the 8th value:
Median = 24
To find the mode, we look for the value that appears most often. In this case, there are three values that appear twice (19, 19, and 19), so there is no single mode.
To find the range, we subtract the smallest value from the largest:
35 - 15 = 20
So the range is 20.
To make a graph, we can create a simple bar graph:
