Question

student mean word length 1 7.1 2 4.5 3 6.9 4 5.2 5 5.0 6 4.7 7 6.1 8 4.5 given this data, what is the range of the average word lengths? is the variation between sample means large or small?

Explanation:

Step1: Find the maximum value

The maximum value in the 'Mean Word Length' column is 7.1.

Step2: Find the minimum value

The minimum value in the 'Mean Word Length' column is 4.5.

Step3: Calculate the range

Range = Maximum - Minimum = 7.1 - 4.5 = 2.6

Step4: Analyze the variation

The values range from 4.5 to 7.1. The differences between values are mostly within 2 - 3 units. Compared to the values themselves, this variation is relatively small.

Answer:

Range of average word lengths: 2.6
Variation between sample means: small
