Type II Error The null hypothesis is not rejected when it is false. There is always a chance of making one of these errors. But, a good scientific study will minimize the chance of doing so! Making the Decision green hell how to fish with spearStandard error and standard deviation are both measures of variability: 1. The standard deviation describes variability within a single sample. 2.
