Mean deviation is a measure of variability in a data set, with a smaller mean deviation indicating less variation.

Mean deviations for three data sets:
1. Data set A: 3, 4, 5, 6, 7. Mean deviation = 1.2
2. Data set B: 10, 12, 14, 15, 18. Mean deviation = 2.8
3. Data set C: 5, 5, 5, 5, 5. Mean deviation = 0

Based on the mean deviations, data set C (mean deviation = 0) has the least variation.

The mean deviation for each data set is as follows:

1. Data set A: 1.2
2. Data set B: 2.8
3. Data set C: 0

Among the given options, the mean deviation closest to 0 (indicating the least amount of variation) is -0.5.

Let's calculate the mean deviation for each data set:

Data set A: 14, 18, 19, 22, 17
Mean = (14 + 18 + 19 + 22 + 17) / 5 = 90 / 5 = 18

Mean deviation = (|14 - 18| + |18 - 18| + |19 - 18| + |22 - 18| + |17 - 18|) / 5
= (4 + 0 + 1 + 4 + 1) / 5
= 10 / 5
= 2

Data set B: 22, 19, 18, 24, 23
Mean = (22 + 19 + 18 + 24 + 23) / 5 = 106 / 5 = 21.2

Mean deviation = (|22 - 21.2| + |19 - 21.2| + |18 - 21.2| + |24 - 21.2| + |23 - 21.2|) / 5
= (0.8 + 2.2 + 3.2 + 2.8 + 1.8) / 5
= 10 / 5
= 2

Both data set A and data set B have a mean deviation of 2, indicating that they have the same amount of variation.

Given the mean deviations for the two data sets provided:

Data set A: 14, 18, 19, 22, 17
Mean deviation = 2

Data set B: 22, 19, 18, 24, 23
Mean deviation = 2

Neither of the given options (1.01, -0.5, 0.01, 10.2) match the calculated mean deviation of 2 for both data sets.

To determine which data set has a higher mean absolute deviation, we can calculate the mean absolute deviation (MAD) for each data set:

Data set A: 14, 18, 19, 22, 17
Mean = (14 + 18 + 19 + 22 + 17) / 5 = 90 / 5 = 18

Calculate absolute deviations from the mean:
|14 - 18| = 4
|18 - 18| = 0
|19 - 18| = 1
|22 - 18| = 4
|17 - 18| = 1

Mean absolute deviation = (4 + 0 + 1 + 4 + 1) / 5 = 10 / 5 = 2

Data set B: 22, 19, 18, 24, 23
Mean = (22 + 19 + 18 + 24 + 23) / 5 = 106 / 5 = 21.2

Calculate absolute deviations from the mean:
|22 - 21.2| = 0.8
|19 - 21.2| = 2.2
|18 - 21.2| = 3.2
|24 - 21.2| = 2.8
|23 - 21.2| = 1.8

Mean absolute deviation = (0.8 + 2.2 + 3.2 + 2.8 + 1.8) / 5 = 10 / 5 = 2

Both data sets have the same mean absolute deviation of 2, so neither data set A nor data set B has a higher mean absolute deviation.
Answered by GPT 3.5
I apologize for the oversight. Let's focus on the given options to determine which one matches the mean absolute deviation for the relevant data set:

Data set A: 14, 18, 19, 22, 17 - Mean absolute deviation is 2
Data set B: 22, 19, 18, 24, 23 - Mean absolute deviation is 2

Among the given options:
1.01, -0.5, 0.01, 10.2

None of the options match the calculated mean absolute deviation of 2 for both data sets A and B.
