A histogram is built of bins with a width representing the interval, and a height representing the quantity of data points in each interval, whereas
A frequency polygon is constructed by drawing a point to represent the frequency of a particular interval and connecting that point to the one representing the frequency.
⟹ histogram :-
- The scores go on the horizontal axis
- Allow a half column width gap at the start
- The area of the column represents the frequency for that score
- The columns have no space between them
⟹ frequency polygon :
- Polygon starts at the corner, one unit before the first score
- The points show the frequency for that score
- Polygon finishes on the axis, one number after the last score
