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.

Find the median of the following data set: 12, 15, 11, 14, 13.

Back

13

Answer explanation

To find the median, first arrange the data in ascending order: 11, 12, 13, 14, 15. The median is the middle value, which is 13 in this case.

Identify the mode of the data set: 4, 5, 6, 6, 7, 8, 8, 8, 9.

Back

8

Answer explanation

The mode is the number that appears most frequently in a data set. In this case, the number 8 appears three times, more than any other number, making it the mode of the data set.

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.

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.

Given the data set: 9, 3, 6, 3, 9, 12, find the mean.

Back

7

Answer explanation

To find the mean, sum the numbers: 9 + 3 + 6 + 3 + 9 + 12 = 42. Then divide by the count of numbers (6): 42 / 6 = 7. Thus, the mean is 7.

Find the median of the following data set: 21, 18, 24, 30, 27.

Back

24

Answer explanation

To find the median, first arrange the data in ascending order: 18, 21, 24, 27, 30. The median is the middle value, which is 24 in this case.

Identify the mode of the data set: 14, 18, 14, 20, 22, 18, 18.

Back

18

Answer explanation

The mode is the number that appears most frequently in a data set. In this case, 18 appears three times, more than any other number. Therefore, the mode of the data set is 18.

Calculate the range of the data set: 45, 32, 37, 50, 41.

Back

18

Answer explanation

To find the range, subtract the smallest value (32) from the largest value (50). So, 50 - 32 = 18. Therefore, the range of the data set is 18.

Mean absolute deviation of the data set: 2, 4, 6, 8, 10.

Back

2

Answer explanation

To find the mean absolute deviation, first calculate the mean: (2+4+6+8+10)/5 = 6. Then, find the absolute deviations: |2-6|=4, |4-6|=2, |6-6|=0, |8-6|=2, |10-6|=4. The mean of these deviations is (4+2+0+2+4)/5 = 2.
