Mean of a data set
Calculate the arithmetic mean of a finite dataset
Problem types
- Mean of a dataset
- Mean and median of six values
Builds on
- The four operations with decimals
- Adding three numbers · Useful idea
The mean begins by adding all the data values, which is adding more than two addends.
Leads to
- Using expected value to compare choices · Extend the idea
Expected value is a mean in which each outcome is weighted by its probability.
- The normal distribution · Extend the idea
The mean is the center of a data set, and a normal model is described by its mean and standard deviation.
- A margin of error from simulated samples · See it applied
The mean of a sample estimates the mean of the population, and the margin of error says how far it may be.
