A histogram would be an appropriate graph for a single variable at the interval-ratio level. Histograms are used to display the distribution of a continuous variable, such as age or income, and are made up of bars that represent the frequency or proportion of values within each interval or bin. Pie charts are not appropriate for interval-ratio level variables because they depict proportions or percentages of a whole, which is not relevant for continuous data. Bivariate tables are useful for examining the relationship between two categorical variables, but not for summarizing a single interval-ratio variable.
