Question

1. what changes to your data set would have caused the standard deviation to be larger?

Explanation:

Step1: Recall standard - deviation concept

Standard deviation measures data dispersion.

Step2: Identify factors increasing dispersion

Larger differences between data points increase dispersion.

Step3: List data - set changes

Adding data points far from the mean or increasing the spread of existing data points will increase standard deviation.

Answer:

Adding data points that are far from the mean of the data - set or increasing the spread of the existing data points (e.g., making the values more spread out from each other) would cause the standard deviation to be larger.
