question
find the median and mean of the data set below:
12, 48, 44, 9, 44
answer attempt 1 out of 2
median =
mean =

Explanation:

Step1: Arrange data in ascending order

$9, 12, 44, 44, 48$

Step2: Find the median

Since there are 5 (odd number) data - points, the median is the middle - value. So, median = $44$.

Step3: Calculate the mean

The formula for the mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $n = 5$, $x_1=9$, $x_2 = 12$, $x_3=44$, $x_4=44$, $x_5=48$. Then $\bar{x}=\frac{9 + 12+44+44+48}{5}=\frac{157}{5}=31.4$.

Answer:

Median = $44$
Mean = $31.4$
