Once the measurements are collected, they can be compared to establish whether the treatment, for example, the use of a new information system, made a difference or not. If that new system makes a difference, then the group of users with that system will score higher than the users without the system. Their scores will still be distributed normally, but, since they are shown to be different, they represent two different populations each with its own normal distribution.
