Answer 1

Answer:

First check whether the classes are continuous

Step-by-step explanation:

First find the class mark of the classes by taking the average of the lower limit and upper limit

i.e. L.L.+U.L./2

Then mark a crink mark on the X-axis

Take one class before the first class and one class after the last class. Write the lower limits of the classes on X-axis. And taking the class marks as x coordinate and the frequency as y-coordinate, plot the points on the coordinate system. join all the points

Note that the frequency polygon begins from the X-axis and terminates on the X-axis.

The class mark is the point between the two lower limits of the classes on the graph paper.

You will get your polygon.
