Question

find the median and mean of the data set below: 43, 49, 6, 5, 9 answer attempt 1 out of 2 median = mean =

Explanation:

Step1: Sort the data - set

$5,6,9,43,49$

Step2: Find the median

Since there are 5 (odd number) data - points, the median is the middle value. So the median is 9.

Step3: Calculate the mean

The formula for the mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $n = 5$, $x_1=5,x_2 = 6,x_3=9,x_4=43,x_5=49$. Then $\bar{x}=\frac{5 + 6+9+43+49}{5}=\frac{112}{5}=22.4$

Answer:

Median = 9
Mean = 22.4
