Question

twenty students participated in a psychology experiment that measured their heart rates in two different situations. the more appropriate measures of center is the and the more appropriate measure of variability is because the distribution is

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
