Statistical hypothesis test comparing observed and expected frequencies.
CHITEST Function in Excel: Calculating Test for Independence The CHITEST function in Excel is a powerful statistical tool used to calculate the test for independence. It determines if there’s a significant association between two categorical variables by returning the probability that the observed data could have occurred by random chance under the null hypothesis. Function […]
Calculates the inverse of the left-tailed probability of the chi-squared distribution.
CHISQ.INV Function in Excel: Inverse of Chi-Squared Distribution The CHISQ.INV function in Excel returns the inverse of the left-tailed probability of the chi-squared distribution. It’s a powerful tool for statistical analysis, particularly in hypothesis testing and confidence interval estimation. Syntax and Parameters CHISQ.INV(probability, deg_freedom) probability: The probability associated with the chi-squared distribution (between 0 and […]
