Question

find the median and mean of the data set below 12, 38, 13, 44, 18

Explanation:

Step1: Sort the data set

$12, 13, 18, 38, 44$

Step2: Find the median

Since there are 5 (odd) numbers, the median is the middle - number. So the median is $18$.

Step3: Calculate the mean

The mean $\bar{x}=\frac{12 + 38+13 + 44+18}{5}=\frac{125}{5}=25$

Answer:

Median: $18$, Mean: $25$
