Statistician can assess the strength of the impact of independent variables (program inputs) on outcomes (program outputs). In ...
s candy line on (just) the samples they have to offer. The same logic holds true for most surveys in stats. You’re only going to want to take a sample of the whole population (“population” in this example would be the entire candy line). The result is a statistic about that ...
