Introduction to Cumulative Frequency and Less Than Type Ogive Graph

The video tutorial introduces cumulative frequency and its graphical representation, the ogive. It focuses on the 'less than' type ogive, using an example of workers' daily income to explain grouped data and frequency distribution. The tutorial demonstrates how to calculate cumulative frequency, plot it on a graph, and find the median using the ogive. The session concludes with a summary of the less than type method.

How do you plot the cumulative frequency on a graph?

Why is it important to set scales on the x-axis and y-axis before plotting a graph?

Summarize the key points of the less than type method discussed in the lesson.
