or
Brett wears a pedometer that tracks his daily steps. This histogram shows his totals for the past two weeks.
Complete the sentences.
The distribution of Brett's daily step counts is best described as
. So, the standard deviation
an appropriate measure of variation.

Answer 1

To complete the sentences about the distribution of Brett's daily step counts based on the histogram, you would typically describe the shape of the distribution (e.g., normal, skewed, uniform) and summarize the measure of variation.

Here’s a possible completion:

The distribution of Brett's daily step counts is best described as **positively skewed** (or **negatively skewed**, **uniform**, etc., depending on the actual shape shown in the histogram). So, the standard deviation **is not** an appropriate measure of variation **(or is)** depending on the distribution shape.

If the data is skewed, sometimes the interquartile range (IQR) could be a more robust measure of variation if you want to avoid the influence of outliers. If the distribution is normal or approximately normal, then the standard deviation would be appropriate.

Please adjust the completion based on your observation of the actual histogram.
