1 * Sea temperatures range from 16Â°C/61Â°F to 23Â°C/74Â°F. * 2  Average number of sunshine days ranges from 95 hours per month during the winter in the Black Sea Coast Region to 375 hours per month in the Aegean, Mediterranean and Central Anatolia Regions.
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.
Using sample data, we will conduct a chi-square test for independence. Analyze sample data. Applying the chi-square test for independence to sample data, we compute the degrees of freedom, the expected frequency counts, and the chi-square test statistic.Based on the chi-square statistic and the degrees of freedom, we determine the P-value. Significance level. 2  Often, researchers choose significance levels equal to 0.01, 0.05, or 0.10; but any value between 0 and 1 can be used. 3  Test method. 4  Use the chi-square test for independence to determine whether there is a significant relationship between two categorical variables.
