find the median and mean of the data set below:
18, 18, 12, 47, 10
answer attempt 1 out of 2
median =
mean =

Explanation:

Step1: Sort the data set

$10, 12, 18, 18, 47$

Step2: Find the median

Since there are 5 (an odd - numbered) data points, the median is the middle value. So the median is 18.

Step3: Calculate the mean

The mean $\bar{x}=\frac{10 + 12+18+18+47}{5}=\frac{105}{5}=21$

Answer:

Median = 18
Mean = 21
