Calculate and interpret mean median and range
Problem types
- Read a stem-and-leaf plot
- Mean from a dot plot
- Find the missing value
- Center from a frequency table
- Find the mode
- Mean, median, mode or range
- Select the statements a dot plot supports
- Select the plots that show a data list
Builds on
- The four operations with decimals
- Adding and subtracting from a line plot · Useful idea
The mean of fractional data adds fractions on the line plot and divides by the number of points.
- Line plots with fractional lengths · Useful idea
The mean of data with fractional measurements adds the values on the line plot, counting each by its number of dots.
- Line plots of lengths · Useful idea
The mean of data on a line plot adds each value as many times as its dots.
- Adding several two-digit numbers · Useful idea
The mean of a dot plot adds several values before dividing.
Leads to
- Dot plots, histograms, and box plots
- Median and spread of signed data
- Comparing center, spread, and shape · Extend the idea
The mean moves toward an outlier and the median does not, which decides which center to report.
