Statwing allows users to apply weights, so that if certain types of survey respondents are under- or over-represented, Statwing can be told that one row of data counts for more or less than one case. To enable weights, your data must have a column of weights (see "Additional Notes" below for more details).
Unless you uncheck that box, all future analyses will be weighted (though if you have a specific analysis that you’d like to not include weights, you can remove the weighting from that individual card):
Weighting can also be used if each row of your data represents several cases. For example, if you have a table that looks like this:
In that case you could upload the data, indicate that “Count” is the column to weight by, and Statwing will produce the same results as if you had loaded a larger table with 45 rows of grey cats, 5 rows of black cats, etc.
