Question

find the median and mean of the data set below: 40, 4, 12, 15, 45, 16 answer attempt 1 out of 2 median = mean =

Explanation:

Step1: Sort the data set

$4, 12, 15, 16, 40, 45$

Step2: Calculate the median

Since there are 6 (an even - numbered) data points, the median is the average of the two middle - numbered values. The two middle values are the 3rd and 4th values. Median=$\frac{15 + 16}{2}=\frac{31}{2}=15.5$

Step3: Calculate the mean

Mean=$\frac{4+12 + 15+16+40+45}{6}=\frac{132}{6}=22$

Answer:

Median = 15.5, Mean = 22
