Use the tables to answer the question.

Table 1

Data Point 11 15 9 10 11 12 12 10 9
Distance from Mean 0 4 2 1 0 1 1 1 2
Table 2

Data Point 9 10 14 14 12 10 10 10 9
Distance from Mean 2 1 3 3 1 1 1 1 2

The first table has a larger average deviation.

1 answer

To compare the average deviations of the two datasets, we need to calculate the average deviation for each table.

Table 1

Distance from Mean: 0, 4, 2, 1, 0, 1, 1, 1, 2
Total Distance: 0 + 4 + 2 + 1 + 0 + 1 + 1 + 1 + 2 = 12
Number of Data Points: 9
Average Deviation: \( \frac{12}{9} = \frac{4}{3} \approx 1.33 \)

Table 2

Distance from Mean: 2, 1, 3, 3, 1, 1, 1, 1, 2
Total Distance: 2 + 1 + 3 + 3 + 1 + 1 + 1 + 1 + 2 = 15
Number of Data Points: 9
Average Deviation: \( \frac{15}{9} = \frac{5}{3} \approx 1.67 \)

Comparison

  • Average Deviation of Table 1: \( \approx 1.33 \)
  • Average Deviation of Table 2: \( \approx 1.67 \)

Conclusion

The second table has a larger average deviation than the first table.

So, the correct response is: The second table has a larger average deviation.
