One Way Chi Square Test Example. We begin by noting the setting and why the goodness of fit test is appropriate. Calculate this formula for each cell one at a time.
X 2 degress of freedom n sample size chi square statistic value p p value. If testing other than equal frequencies use p to specify the relative proportions for example if testing the hypothesis that the choice proportions would be 1 4 1 2 and 1 4 use chisq test obs p c 25 5 25 chi squared test for given probabilities data. Null and alternative hypotheses.
This is the basic format for reporting a chi square test result where the color red means you substitute in the appropriate value from your study.
Calculate this formula for each cell one at a time. If you have the one continuous variable of salary and you want to determine whether the difference between the mean salary and 20 000 is statistically significant or not you d need to use a one sample t test. Our variable of color is. Now calculate chi square using the following formula.
