Question
Find the median and mean of the data set below:50, comma, 13, comma, 11, comma, 25, comma, 17, comma, 4350,13,11,25,17,43
Solution
Sure, let's start with arranging the data set in ascending order: 11, 13, 17, 25, 43, 50.
- To find the median: The median is the middle number in a sorted, ascending or descending, list of numbers. If there is an even number of observations, the median will be the average of the two middle numbers. In this case, we have 6 numbers, so the median is the average of the 3rd and 4th numbers.
Median = (17 + 25) / 2 = 21
- To find the mean: The mean is the average of all numbers and is found by adding all numbers in the data set and then dividing by the count of numbers.
Mean = (11 + 13 + 17 + 25 + 43 + 50) / 6 = 26.5
So, the median of the data set is 21 and the mean is 26.5.
