Question

The scores for today’s math quiz are 75, 95, 60, 75, 95, and 80. Explain the steps needed to create a histogram for the data.

Answer 1

Answer:

A histogram is a bar graph which shows frequency (here-->score) distribution.

Steps to make a histogram :

1. On the vertical axis, place scores. Label this axis "Scores".
2. On the horizontal axis, place the lower value of each interval. Label this axis with the type of data shown (names, student ID etc.)
3. Draw a bar extending from the lower value of each interval to the lower value of the next interval. The height of each bar should be equal to the score of its corresponding interval.

See example attached.

Answer 2

Answer:

Determine what should go on each axis. Grades will go on the x-axis, and the number of students will be plotted on the y-axis. Find the number of different scores and range. Choose an interval – say, 10 percent. Find the frequency within each interval. Choose a scale – say, 0–3. Draw bars the height of the frequency for each interval.
