Question

find the median and mean of the data set below:
21, 40, 48, 26, 32, 31
answer attempt 1 out of 2
median =
mean =

Explanation:

Step1: Find the median

First, sort the data set: \(21, 26, 31, 32, 40, 48\). Since there are 6 (even) numbers, the median is the average of the 3rd and 4th values. So, \(\frac{31 + 32}{2} = \frac{63}{2} = 31.5\).

Step2: Find the mean

Sum the data: \(21 + 40 + 48 + 26 + 32 + 31 = 198\). Then divide by the number of values (6): \(\frac{198}{6} = 33\).

Answer:

Median = \(31.5\)
Mean = \(33\)
