WebChi-Square Test Statistic. χ 2 = ∑ ( O − E) 2 / E. where O represents the observed frequency. E is the expected frequency under the null hypothesis and computed by: E = row total × column total sample size. We will compare the value of the test statistic to the critical value of χ α 2 with degree of freedom = ( r - 1) ( c - 1), and ... WebThe t-table indicates that the critical values for our test are -2.086 and +2.086. Use both the positive and negative values for a two-sided test. Your results are statistically significant if your t-value is less than the negative value or greater than the positive value. The graph below illustrates these results.

WebMay 12, 2024 · When we have two categorical variables, our frequency table is crossed. That is, each combination of levels from each categorical variable are presented. This type of frequency table is called a contingency table because it shows the frequency of each … WebUsually, the significance level is p = 0.05, although this value can change. The 'p' stands for probability. A p-score of .05 suggests there is a 5% probability the results we found are due to chance. And p = .01 means there is a 1% probability of the results being due to chance. ... The critical values table allows the comparison of observed ...
