    confused by this.

    to calculate a standard deviation OP would have to buy a few packets anyways.

    if you maybe wanna buy 100 to find what the standard deviation is, by definition, only 68% of them will be within a standard deviation (assuming the weights are normally distributed)

      Usually foods are regulated that the standard deviation falls within some range of grams. Sorry if I was unclear.
