Question

Find the mean, median, and mode of the data set. Round to the nearest tenth. 15, 1, 4, 4, 8, 7, 15, 4, 15, 4, 5

A. mean = 6.8, median = 5, mode = 4


B. mean = 7.5, median = 5, mode = 4


C. mean = 7.5, median = 8, mode =4


D. mean = 6.8, median = 5, mode = 8

Answer 1

Mean - Average of the numbers

To find the mean you add all the numbers together and divide by how many numbers there are:

15+1+4+4+8+7+15+4+15+4+5= 82
82/11= 7 5/11 or 7.45

Median - Middle number

To find the median you put all the numbers in numerical order; the median is the middle number, but if there are two numbers than you add them together and divide by two:

1,4,4,4,4,5,7,8,15,15,15,15
5+7=12
12/2=6

Mode - Number that occurs the most

To find the mode you just look at the number that occurs the most times:
4,4,4,4
4


Your answer is: Mean: 7.45; Median: 6; Mode: 4

Have an amazing day!

Answer 2

Mean = 7.5
Median = 5
Mode = 4
