Answer

Explanation:

Step1: Analyze the data distribution

The dot - plots show data that is not symmetric and may have outliers.

Step2: Select measure of center

When the distribution is skewed or has outliers, the median is a better measure of center than the mean as the mean is affected by extreme values.

Step3: Select measure of variability

For non - symmetric distributions, the inter - quartile range (IQR) is a better measure of variability than the standard deviation as the standard deviation is sensitive to outliers.

Answer:

Median; Inter - quartile range (IQR); skewed
