WebLeft-tail critical value: 1 – (0.05 / 2) = 0.975. In the chi-square table below, I highlight these two results. The chi-square table shows that our lower critical value is 0.831 and the upper critical value is 12.833. Consequently, our results are statistically significant if the χ 2 test statistic when ≤ 0.831 or ≥ 12.833. WebMay 19, 2024 · If the F statistic is greater than the F critical value, then the results of the test are statistically significant. The F critical value can be found by using an F distribution table or by using statistical software. To find the F critical value, you need: A significance level (common choices are 0.01, 0.05, and 0.10) Numerator degrees of freedom

WebApr 7, 2024 · So the P-value is 0.4643. The P-value is defined as a the probability of getting a result that is 'as or more extreme' than the observed F-ratio.

WebTwo-tailed test: Look for α / 2 in the negative z-table. Suppose we need to find the critical values that correspond to the significance level of 0.05. We’ll find the critical values for both a one- and two-tailed z-test. Learn more about significance levels, test statistics, critical values, and one- vs. two-tailed hypothesis tests. WebTherefore, alpha is 0.04. Right tail alpha is 0.04/2=0.02 and left tail alpha is 1-0.02= 0.98. So the two F's that I end up working with are .98 and .02. My F table does not have the values. … WebTo decide if a one-tailed test can be used, one has to have some extra information about the experiment to know the direction from the mean (H1: drug lowers the response time). If the direction of the effect is unknown, a two tailed test has to be used, and the H1 must be stated in a way where the direction of the effect is left uncertain (H1 ... paratracheal space
