Question
Find the median and mean of the data set below:9, comma, 43, comma, 50, comma, 09,43,50,0
Solution 1
Sure, let's start with arranging the data set in ascending order: 0, 9, 9, 43, 50.
Step 1: Find the Median The median is the middle number in a sorted, ascending or descending, list of numbers. This data set has 5 numbers, so the median is the third number, which is 9.
Step 2: Find the Mean The mean is calculated by adding all numbers in the data set and then dividing by the count of numbers in the set.
So, add all the numbers together: 0 + 9 + 9 + 43 + 50 = 111 Then, divide by the count of numbers, which is 5: 111 ÷ 5 = 22.2
So, the median of the data set is 9 and the mean is 22.2.
Solution 2
Sure, let's start with arranging the data set in ascending order: 0, 9, 9, 43, 50.
-
To find the median, we need to find the middle number. Since there are 5 numbers, the median is the third number, which is 9.
-
To find the mean, we add all the numbers together and then divide by the number of numbers.
(0 + 9 + 9 + 43 + 50) / 5 = 111 / 5 = 22.2
So, the median of the data set is 9 and the mean is 22.2.
Solution 3
Sure, let's start with arranging the data set in ascending order: 0, 9, 9, 43, 50.
-
To find the median, which is the middle number in a sorted list, we see that our sorted list has 5 numbers. So, the median is the 3rd number, which is 9.
-
To find the mean, we add up all the numbers and then divide by the count of numbers. So, (0 + 9 + 9 + 43 + 50) / 5 = 111 / 5 = 22.2.
So, the median of the data set is 9 and the mean is 22.2.
