A histogram is a graphical display of data using bars of different heights. It is similar to a bar graph, but it groups numbers into ranges (called 'bins' or 'intervals'). The height of each bar shows how many data points fall into that range.
1. What is the main difference between a bar graph and a histogram?
Histograms use different colors for bars.
Histograms group numbers into ranges.
Bar graphs can only show two categories.
Histograms do not have an x-axis.
Use the histogram below to answer the following questions:
2. How many students scored between 70-79?
3. Which score range has the most students?
4. How many students took the math test in total?
5. In a histogram, the bars touch each other because the data is .
6. The ranges or intervals in a histogram are often called .
7. The vertical axis (y-axis) on a histogram usually represents the .
8. A group of students recorded the number of hours they spent reading last week:
2, 5, 8, 3, 10, 7, 4, 6, 9, 1, 5, 8, 2, 7, 3, 10, 6, 4
Create a frequency table with intervals of 2 hours (0-1, 2-3, 4-5, etc.) for this data.
9. All histograms must have exactly 5 bars.
True
False
10. The bars in a histogram always represent continuous data.
True
False
