Question

which best explains how the histogram is useful for comparing the shapes of the data sets? it is easier to visually compare the means of the data. it is easier to visually compare the standard deviations of the data. it is easier to visually compare the medians of the data. it is easier to visually compare symmetry and skew of the data.

Explanation:

Histograms display the distribution of data. By looking at the bars for each data - set (City A and City B here), one can easily observe if the data is symmetric (evenly distributed on both sides of a central value), skewed (more data on one side), etc. Means, standard deviations, and medians are not as straightforward to visually compare on a histogram.

Answer:

It is easier to visually compare symmetry and skew of the data.
