Question
Find the median and mean of the data set below:20, comma, 46, comma, 20, comma, 2620,46,20,26
Solution 1
Sure, let's start with the mean first.
Step 1: Add all the numbers together. 20 + 46 + 20 + 26 = 112
Step 2: Divide the sum by the total number of data points. 112 ÷ 4 = 28
So, the mean of the data set is 28.
Now, let's find the median.
Step 1: Arrange the data in ascending order. 20, 20, 26, 46
Step 2: Since there are 4 numbers (an even number), the median is the average of the two middle numbers. (20 + 26) ÷ 2 = 23
So, the median of the data set is 23.
Solution 2
Sure, let's start with the mean first.
Step 1: Add all the numbers in the data set together.
20 + 46 + 20 + 26 = 112
Step 2: Divide the sum by the total number of data points.
112 ÷ 4 = 28
So, the mean of the data set is 28.
Now, let's find the median.
Step 1: Arrange the data points in ascending order.
20, 20, 26, 46
Step 2: Since there are 4 data points (an even number), the median is the average of the two middle numbers.
(20 + 26) ÷ 2 = 23
So, the median of the data set is 23.
