Solution
An Ogive is a method in which cumulative frequency is plotted.
Explanation:
An ogive (also called a cumulative frequency curve) is a specific type of line graph used in geographical and statistical analysis. It does not simply show isolated counts; instead, the frequencies of each class interval are sequentially added up to create a running total. When this cumulative frequency is plotted against the class boundaries on the graph, it forms a distinct, smooth, rising curve. This plotting method makes it incredibly easy to visually calculate advanced statistics like the median, quartiles, and percentiles.
