Answer:
Frequency Polygon and Histogen.
Step-by-step explanation:
Frequency Polygon-Frequency Polygon is another method of representing frequency distribution graphically.
Obtain the frequency distribution and compute the mid points of each class interval.
Represent the mid points along the X-axis and the frequencies along the Y-axis.
Plot the points corresponding to the frequency at each mid point.
Join these points, by straight lines in order.
To complete the polygon join the point at each end immediately to the lower or higher class marks (as the case may be at zero frequency) on the X-axis.
Histogen- A two dimensional graphical representation of a continuous frequency distribution is called a histogram.
In histogram, the bars are placed continuously side by side with no gap between adjacent bars.
That is, in histogram rectangles are erected on the class intervals of the distribution. The areas of rectangle are proportional to the frequencies.
