Question
Find the median and mean of the data set below:
- Data Set: 35, 9, 17, 7, 45, 3, 2435, 9, 17, 7, 45, 3, 24
Solution
Sure, let's start with the mean first:
Step 1: Add all the numbers together. 35 + 9 + 17 + 7 + 45 + 3 + 24 = 140
Step 2: Divide the sum by the total number of data points. 140 ÷ 7 = 20
So, the mean of the data set is 20.
Now, let's find the median:
Step 1: Arrange the data in ascending order. 3, 7, 9, 17, 24, 35, 45
Step 2: Find the middle number. Since there are 7 numbers, the middle number is the 4th one, which is 17.
So, the median of the data set is 17.
