You are running a chi-squared test. You have 2 groups with 3 characteristics each, what would your critical value be with an alpha of .025? A. 7.378 B. 2.773 C. 12.7062 D. 5.024 E. 12.833 Chi-Square Goodness-of-Fit Test: Let's check to see is RStudio'...
Notice the calculated chi-squared statistic (3.66) and p-value (0.1608) obtained using R are the same values as computed by the demo program. The demo concludes by using the calculated chi-squared statistic to compute the p-value: C# ...
If the formula for the Cramer’s V provided in this section is accurate, the effect should be 0.1986 for the Pearson’s test. This value came from the squared value of {Pearson’s chi-square statistic (13.491) divided by [the sample size (171) *df (2)]}. The values listed under th...
