Chi-square distribution, showing X 2 on the x-axis and P-value on the y-axis. A chi-squared test, also referred to as test (or chi-square test), is any statistical hypothesis test in which the sampling distribution of the test statistic is a chi-square distribution when the null hypothesis is true.hen T has a chi-square distribution with n â 1 degrees of freedom. For example if the sample size is 21, the acceptance region for T for a significance level of 5% is the interval 9.59 to 34.17.
Three of these variables are categorical, frequent ocean swimmer status, location, and sex, and two are ordinal, age group and number of ear infections. To illustrate a chi-square test of goodness of. fit, we will use the age group variable. We want to examine whether the sample frequency distribution fits a. hypothesized population distribution of 50% in the youngest age group and 25% in the two older age groups.
