Critical Values for Statistical Significance ! The z-score needed to reject H 0 is called the critical value for significance. ! The critical value depends on the significance level, which we state as α. ! Each type of alternative hypothesis has it’s own critical values: " One-sided left-tailed test " One-sided right-tailed test

Steps to follow • State the hypothesis • Calculate the expected values • Use the observed and expected values to calculate the chi-square test statistic • Establish the significance level you need (usually 95% p = 0.05) and the number of degrees of freedom • Compare the chi-square statistic with the critical value from the table • Make a decision about your hypothesis
