A histogram would be the most appropriate choice to summarize the frequency of children falling into different intervals of time, as it displays the frequency distribution of a continuous variable (time in this case) into intervals or bins. Each bar on the histogram represents the number of observations falling into a particular interval, giving a clear visual representation of the distribution of the data. A bar chart is used to display categorical data, while a scatter gram is used to show the relationship between two continuous variables.
