Detailed Solution

Graphical Representation is a method of evaluating numerical data by depicting the link between facts, ideas, information, and concepts in the form of a diagram.

Now let us consider each option.

Bar Graph: The Bar Graph is used to depict the category of data and compare the data by using solid bars to indicate the quantities.
Histogram: The graph in which the frequency of numerical data organized into intervals is represented by bars. All of the bars have the same width since all of the intervals are equal and continuous.
Frequency Polygon: A frequency polygon is a line graph of class frequency plotted against a class midpoint.
Cumulative Frequency Distribution: A cumulative frequency is defined as the total of frequencies, that are distributed over different class intervals.

So, Cumulative frequency distribution is not a graphical representation of data. It is a tabular representation of statistical data.
