A First Look at Empirical Testing: Creating a Valid Research Design
... • We as researchers often assume that our data is normally distributed (the well-known bellshaped graph!). If so, all three measures of central tendency or averages will converge. If not, they can differ substantially, so we need to be careful about which measure of the average to report (Ex.: for p ...

In a statistical context, the scientist may pose a theory concerning one or more population parameters – for example that that they equal specified values. Then the scientist samples the population and compares observation agai ...
