FLASHCARD QUESTION

Front

Calculate the mean of the data set: 3, 7, 7, 2, 5, 10, 8.

Back

6

Answer explanation

To calculate the mean, sum the numbers: 3 + 7 + 7 + 2 + 5 + 10 + 8 = 42. Then divide by the count of numbers (7): 42 / 7 = 6. Thus, the mean is 6.

FLASHCARD QUESTION

Front

Calculate the range of the data set: 22, 29, 15, 18, 25.

Back

14

Answer explanation

To find the range, subtract the smallest value (15) from the largest value (29). So, 29 - 15 = 14. Therefore, the range of the data set is 14.

FLASHCARD QUESTION

Front

Determine the mean absolute deviation of the data set: 5, 10, 15, 10, 5.

Back

2

Answer explanation

To find the mean absolute deviation, first calculate the mean: (5+10+15+10+5)/5 = 10. Then, find the absolute deviations: |5-10|, |10-10|, |15-10|, |10-10|, |5-10| = 5, 0, 5, 0, 5. The mean of these deviations is (5+0+5+0+5)/5 = 2.
