Answer:
Chill, it ain't complicated
Explanation:
A histogram is basically a bar graph but there's no space between the bars.
The graph has to be the dependent component (the score) against the independent component (the number of students who took the math quiz)
Depending on your size of paper pick a simple scale (1 cm could be either 5% or 10%)
Leave some space between the y (vertical) axis and the first bar.
Do them in the order they appear, i.e 75, 95... 80
