The chi-square distribution (also called the chi-squared distribution) is a special case of the gamma distribution; A chi square distribution with n degrees of freedom is equal to a gamma distribution with a = n / 2 and b = 0.5 (or β = 2). Let’s say you have a random sample ta...
Sum of Squares (Σx²): This computes the sum of the squared values in a set. Sum Squared (Σx)²: This computes the square of the summed values in a set. Mean (μ): This computes is the mean (average) of values in a set. Median: This identifies the middle ordered value in...
A chi-squared test is any statistical hypothesis test in which the sampling distribution of the test statistic is a chi-squared distribution when the null hypothesis is true. Chi Square FormulaX2 = ∑ (Observed Value-Expected Value)2 (Expected Value) ...
