How old are women when they have their first child? The table displays the distribution of the age of the mother for all
firstborn children in the United States in 2017.
Why are histograms of percentages in each age class preferable to counts for comparison with other years and with
other countries?
O Percentages and counts provide the same information, so it does not matter which is used to make a histogram.
O It is more straight-forward to make a histogram with percentages than it is with counts.
Percentages account for population size, so they allow for direct comparisons between groups of varying sizes.
Percentages are on a smaller scale, so they are easier to compare between groups.

The reason that percentages are used for the histogram is given by:

Percentages account for population size, so they allow for direct comparisons between groups of varying sizes.

What is an histogram?

An histogram is a graph that shows the number of times each element of x was observed.

When different sized measures are compared, percentages are recommended, and one example is the age of the mother of first born children in this problem, as the US has a large population, hence all bins will have large absolute numbers, greater than other countries with smaller populations, but the percentages will be a better measure to see for example how young the mothers are when they have their first children.

Hence the correct option is:

Percentages account for population size, so they allow for direct comparisons between groups of varying sizes.
