A histogram would be most appropriate for summarizing the frequency of children falling into different intervals of time. This is because a histogram displays the distribution of a continuous variable, such as time, into intervals or bins, and shows the frequency of observations that fall into each bin. A bar chart would not be appropriate as it is used for discrete variables, and a scatter gram is used to display the relationship between two continuous variables.
