Lesson details
Key learning points
- There may be cases where one value has more weight (importance).
- The weighted mean takes this into account.
- The percent weight given to each value is called a weighting factor.
Keywords
Weighting factor - A weighting factor is a multiplier used to reflect the importance of a piece (or pieces) of data relative to the rest of the data.
Weighted mean - A weighted mean is the mean calculated for a set of data where weighting factors have been applied.
Common misconception
That for all situations the weightings are subjective.
There are situations in which a subjective decision is made about weightings but there are also situations where the multipliers used are dictated by the context in a logical way. An example of this is combining groups and combining their means.
