Question

Maria was foing a assroom survey. She asked the girls in the class how many siblings they had and recorded the results: 1,2,3,6,7,9,9,9,10. Determine the mean (rounded to the nearest tenth) the median, mode, and range of the results

Answer 1

Mean: The sum of all the numbers, divided by the amount of numbers in the set.

56 / 9 = 6.2

Median: The middle value of a set.

7

Mode: The value that occurs most frequently.

9

Range: The highest number of the set subtracted by the lowest number.

10 - 1 = 9

Hope this helps you!

Answer 2

Median: 7 because it is in the very middle of the numbers

Mean: add up all the numbers and divide by how many numbers there are. So the mean should be 56÷9=6.2. 6.2(2 is repeating) is the mean

Range: the range is the difference between the highest and lowest numbers. so that means the range is 10-1=9. the range is 9
