1. Find the mean, median, and mode of the data set. Time spent on Internet (min/day): 75, 38, 43, 120, 65, 48, 52

Solution:

In order to find the Mean, we simply need to add all the values and divide by the total number of values.

Mean = (75 + 38 + 43 + 120 + 48 + 65 + 52)/7
Mean = 441/7
Mean = 63

In order to find the Median, we simply need to arrange the values from least to greatest and then, determine the middle number.

= 38, 43, 48, 52, 65, 75, 120
Median = 52

In order to find the Mode, we must determine the number of values that is most occurring. In our case we have none.

Final answer:

D) mean: 63, median: 52, no mode

2. Tell which measure of central tendency best describes the data. TIme spent on Internet (min/day) A) Mean B) Median C) Mode

Explanation:

The central of tendency the describes the data is simply the Mean.

Final answer:

A. Mean

3. Tell which measure of central tendency best describes the data. Weights of books (oz): 12, 10, 9, 15, 16, 10

Explanation:

The central tendency of the weights of the book that best describes the data is simply the Mean.

Final answer:

A. Mean
