Because statistical significance measures the probability of an occurrence being genuine, its symbol is the lowercase letter p. At some point way back in the history of statistics, it was mutually agreed upon that an occurrence with a probability of 1 in 20 would be unlikely to occur by pure...
What Is a Chi-Square (χ2) Statistic? A chi-square (χ2)statistic is a test that measures how a model compares to actual observed data. The data used in calculating a chi-square statistic must be random, raw, mutually exclusive, drawn from independent variables, and drawn from a large ...
