... Computing the sum of squared deviations by subtracting the mean from each value, then squaring, requires two passes through the numbers – one pass to compute the mean, a second pass to compute the deviation scores, square them, and sum. It is possible to compute the variance in one pass through the ...

... Descriptive statistics show how often or how frequent an event or score occurred. Inferential statistics help researchers know whether they can generalize their findings to a population based upon their sample of participants. Inferential statistics use data to assess likelihood—or probability. ...
