Question

using box plots to compare data distributions
use these plots below the distributions of daily
january temperature in 7t, for the month of january for two
cities
which statements are true about the distributions?
check all that apply
cedar rapids
longview
both distributions are symmetric.
both distributions are skewed right
both distributions are skewed left
the mean and standard deviation would be the
best measures to compare the data.
the median and iqr would be the best measures
to compare the data.

Explanation:

Step1: Analyze box - plot properties

Box - plots are used to analyze skewness. If a distribution is symmetric, mean and standard deviation are good measures. If skewed, median and IQR are better.

Step2: Check skewness

Cedar Rapids is skewed left (whisker on the left is longer), Longview is skewed right (whisker on the right is longer). So mean and standard deviation are not good. Median and IQR are appropriate.

Answer:

The median and IQR would be the best measures to compare the data.
