      In each sample, there are 100 (n, sample size) individual scores and we can calculate the mean for each sample. The distribution of those 1,000 sample means is normal and centered about the population mean (the Central Limit Theorem). In reality we generally only work on one sample, but we can use the statistics of this sample to estimate the ...
