Question
Given 2, 7, 4 ,4 ,3 ,7 ,3 ,2 ,3 ,5 find the following.
mean Blank 1
median Blank 2
mode Blank 3
Solution
Blank 1: The mean is calculated by adding all the numbers in the set and dividing by the count of numbers. So, (2+7+4+4+3+7+3+2+3+5)/10 = 4
Blank 2: The median is the middle number in a sorted list. If the list has an even number of observations, the median is the average of the two middle numbers. First, we need to sort the numbers: 2, 2, 3, 3, 3, 4, 4, 5, 7, 7. The two middle numbers are 3 and 4. So, the median is (3+4)/2 = 3.5
Blank 3: The mode is the number that appears most frequently in a data set. In this case, the number 3 appears three times, more than any other number. So, the mode is 3.
