The chi-square distribution is characterized by degrees of freedom, which is the number of independent variables in the sample. It is denoted by (χ²) and is a special distribution often used in statistical hypothesis testing. The Excel function CHISQ.INV.TEST is used to calculate the p-value of a chi-square test. The statement that it has a left-tail area equal to the expected value of the sample is incorrect.
