So if a scale has 30 items in it, and if an individual gets a score of 20 what does this mean? The only way to answer this is to look at the standardization sample, find out what the mean score in the sample was, let's say 15, and standard deviation in the population was f...

1. P = positive results / total attempts. In this case, 11/50 = .22 = 22% 2. Increase the sample size. The more data he accrues, the closer the experimental probability will be to the theoretical probability.
