Answer:
Mean - 5.625
Median - 4.5
Mode - 4 and 7
Range - 14
Step-by-step explanation:
The mean is the average of all of the numbers
The average is all the numbers added up then divided by how many numbers there are
2+4+7+7+4+5+15+1 = 45
45÷9=5.625
The median is the middle number
Order the numbers from least to greatest then take up numbers until you get to the middle
1, 2, 4, 4, 5, 7, 7, 15
2, 4, 4, 5, 7, 7
4, 4, 5, 7
4, 5
The middle of 4 and 5 is 4.5
The mode is the number(s) that appear the most
4 and 7 both appear twice while every other number only appears once
The range is the difference between the highest and lowest number
15 is the highest and 1 is the lowest so you do:
15-1 = 14
