... X2 is usually calculaed in table form. Once the X2 value for an experiment has been calculated, it must be evaluated by comparison with a table of X2 values. In order to use the X2 test properly, one must understand exactly what is being evaluated. The X2 test is always phrased in terms of the “Null ...

... The mean (μ), or expected value, is π and the variance can be calculated as π (π-1), which in this case, will be 0.3(0.7) or 0.21. You can see that in this type of distribution the variance and the mean cannot be independent—that is, the variance is tied to the mean. This is one key difference betwe ...

Alternatively, we could imagine the same pair of dice thrown N times under similar circumstances. The probability of ...
