A grouped frequency table is the best choice when there are too many values for a variable to be summarized in a regular frequency table. Grouping the values into intervals will make the table more manageable and easier to interpret. Histograms and frequency polygons are graphical representations of frequency distributions and do not necessarily make the table more manageable. A bar chart is a graphical representation of categorical data and is not suitable for continuous variables.
