Explanation:
Detailed explanation-1: -The graphical representation of a cumulative frequency table is called a histogram.
Detailed explanation-2: -An ogive is a graphical representation of a cumulated frequency distribution. This is a type of frequency graphic and is also called a cumulated frequency polygon. It serves to give the number (or proportion) of observations smaller than or equal to a particular value.
Detailed explanation-3: -A frequency distribution can be graphed as a histogram or pie chart. For large data sets, the stepped graph of a histogram is often approximated by the smooth curve of a distribution function (called a density function when normalized so that the area under the curve is 1).
