Question 1 (3 points)
What is the mean, median, mode, and range of the following test
scores: 14, 8, 13, 13, 12, 10, 15, 12, 7, 14, 14
Mean: 13. Median: 12, Mode: 14, Range: 8
Mean: 12. Median: 13, Mode: 14, Range: 8
Mean: 12. Median: 13, Mode: 8. Range: 14
Mean: 13, Median: 12, Mode: 8, Range: 14

The mean is 12, The median is 13, The mode is 14, and the range is 8.

The second choice is the correct answer.

Explanation:

I found the mean by adding up all the numbers and dividing by the number of numbers, or sun divided by count. The sum of the numbers was 132, and the count was 11. I divided 132 by 11 to get 12.I listed the numbers in order from least to greatest. The data set was: 7, 8, 10, 12, 12, 13, 13, 14, 14, 14, 15I found the median by crossing off the number on each end of the data set, and kept going. For example, I crossed off 8, and then 15, and then 10, and then 14 and so on until I got to the middle number. (Keep in mind, if there are two middle numbers, find the mean of them [add them and divide by two])The mode is the number that shows up the most in the data set, so I looked at the data set and saw that 14 showed up 3 times, more times than any other number.The range is the difference between the greatest and least number (maximum and minimum) so I just subtracted 15 - 7 to get a difference of 8.
