The correct answer is: A. A graph of a cumulative frequency distribution.
An ogive is a graph of a cumulative frequency distribution. It is a type of line graph that shows the cumulative frequency of a variable. The cumulative frequency is the total number of observations that are less than or equal to a certain value. The ogive is constructed by plotting the cumulative frequency against the value of the variable. The ogive can be used to identify the median, mode, and other percentiles of the data.
Option B is incorrect because an ogive is a graph of a cumulative frequency distribution, not a non-linear relationship.
Option C is incorrect because an ogive is not another name for a histogram. A histogram is a type of bar graph that shows the frequency of data values. An ogive is a type of line graph that shows the cumulative frequency of data values.
Option D is incorrect because an ogive is not a chart showing any linear relationship. An ogive is a graph of a cumulative frequency distribution.
