Find the median and mean of the data set below:31, comma, 38, comma, 35, comma, 36, comma, 331,38,35,36,3
Question
Find the median and mean of the data set below:31, comma, 38, comma, 35, comma, 36, comma, 331,38,35,36,3
Solution 1
First, let's arrange the data set in ascending order: 3, 31, 35, 36, 38.
To find the median, we need to find the middle number. Since there are 5 numbers, the median is the third number, which is 35.
To find the mean, we add all the numbers together and then divide by the number of numbers.
So, (3 + 31 + 35 + 36 + 38) / 5 = 28.6
Therefore, the median is 35 and the mean is 28.6.
Solution 2
Sure, let's start with arranging the data set in ascending order: 3, 31, 35, 36, 38.
-
To find the median: The median is the middle number in a sorted, ascending or descending, list of numbers. In this case, our sorted list is 3, 31, 35, 36, 38. The median is 35, as it is the number in the middle of the list.
-
To find the mean: The mean is calculated by adding all numbers in the data set and then dividing by the count of numbers. In this case, (3 + 31 + 35 + 36 + 38) / 5 = 28.6.
So, the median of the data set is 35 and the mean is 28.6.
