Statisticiansdefine two types of errors in hypothesis testing. Creatively, they call these errors Type I and Type II errors. Both types of error relate to incorrect conclusions about the null hypothesis. The table summarizes the four possible outcomes for a hypothesis test. ...

This article assumes readers' familiarity with concepts of a normal distribution table, formula, p-value and related basics of statistics. Different methodologies exist for hypothesis testing, but the same four basic steps are involved: Step 1: Define the Hypothesis Usually, the reported value (or ...
Null-Hypothesis Testing with the T-TableIn the previous chapter we discussed that the patterns of Gaussian curve from biological data have a constant frequency distribution and that this phenomenon is used for making predictions from your d
