Histograms with equal bar width
I can construct bar charts for continuous data.
Lesson details
Key learning points
- A histogram is a bar chart for continuous data
- The bars are adjacent due to the nature of the data
- The bars are all the same width to allow easier comparisons
Common misconception
Histograms with unequal bar widths are plotted against the frequency and/or pupils read the frequency density as the frequency of the class width.
Show what a histogram with unequal bar widths looks like when plotted against frequency. This visual aid will show pupils the distribution of data is difficult to see.
Keywords
Histogram - A histogram is a diagram consisting of rectangles whose area is proportional to the frequency in each class and whose width is equal to the class interval.
