find the median and mean of the data set below:
37, 27, 1, 31, 27, 40, 47
answer attempt 1 out of 2
median =
mean =

Explanation:

Step1: Sort the data set

$1, 27, 27, 31, 37, 40, 47$

Step2: Find the median

Since there are 7 (an odd - numbered) data points, the median is the 4th value. So the median is 31.

Step3: Calculate the mean

The sum of the data points is $1 + 27+27 + 31+37+40+47=200$. There are 7 data points. The mean is $\frac{200}{7}\approx28.57$.

Answer:

Median = 31
Mean $\approx28.57$
