Dot plots, histograms, and box plots
Interpret dot plots histograms and box plots
Problem types
- Combine values from a stem-and-leaf plot
- Match raw data to its dot plot, histogram or box plot
- Build a stem-and-leaf plot
- Choose the best display
- Read a histogram
- Read a box plot
Builds on
- Mean and median
- Line plots of lengths
- Center, spread, and shape of a distribution · Earlier idea
Center, spread and shape describe a distribution in words. The median, the mean, the range and a box plot measure those same features with numbers.
- Frequency tables and scaled bar graphs · Earlier idea
A frequency table counts how many numbers fall in each equal interval. A histogram draws those counts as bars.
- Reading scaled picture and bar graphs · Earlier idea
Reading a scaled graph means using the axis scale. Histograms also need their scale to read frequencies.
- Picture graphs and bar graphs · Earlier idea
A bar graph of categories becomes a histogram when the bars show how many values fall in each interval.
Leads to
- Describing spread and outliers
- Defining a random variable
- The normal distribution · Extend the idea
A histogram of many values that is symmetric and bell-shaped is described by a normal distribution.
