Answer:
Mode) 7
Median) 6
Mean) 5.2
Range) 7
Explanation:
Let's start with what we have:
3, 7, 2, 4, 7, 5, 7, 1, 8, 8
a) The first part of the question we have to do is figure out the mode. The mode of a group of numbers is the number most repeated, which in this case is:
Mode) 7
b) The median of a data set is the number in the middle when ordered from least to greatest. When reordering it, we get:
1,2,3,4,5,7,7,7,8,8
So the number in the middle is...
There is no number in the middle so we have to find the mean of the middlemost numbers which are 5 and 7. Calculating (5 + 7)/2 we get 6, so.
Median) 6
c) The mean of a data set is when we add up all the numbers and then divide by the number of numbers, in this case, is 10. The sum of the numbers is 52. When dividing 52 by 10 we get:
Mode) 5.2
d) The range of a data set is the difference between the greatest number and the smallest number. When subtracting 1 from 8 we get:
Range) 7
