Range Variance and Standard Deviation
... • The values of the standard deviation is usually positive. It is zero only when all of the data values are the same number (can not be negative). A larger value indicate greater amounts of variation. • The value of the standard deviation can increase dramatically with the inclusion of several outli ...

Chi square intro
... • X2 less than 3.84 means that we accept the Null Hypothesis (3:1 ratio). • In our example, p = 0.48 (p > 0.05) means that we accept the Null Hypothesis (3:1 ratio). • This means we expect the data to vary from expectations this much or more 48% of the time. Conversely, 52% of the repeats would show ...
