Weighting is a technique in survey research where the tabulation of results becomes more than a simple counting process. It can involve re-balancing the data in order to more accurately reflect the population and/or include a multiplier which projects the results to a larger universe.
What does it mean when data is weighted?
A weighted mean is a kind of average. Instead of each data point contributing equally to the final mean, some data points contribute more “weight” than others. If all the weights are equal, then the weighted mean equals the arithmetic mean (the regular “average” you're used to).
How does sample weighting work?
Sampling weights are often thereciprocalof the likelihood of being sampled (i.e., selection probability) of the sampling unit. For example, if you have selected 200 goldfish out of a population of 1000, the reciprocal of the likelihood of being selected is 1000/200, so the sampling weight for the goldfish would be 5.
