It can be shown using either statistical software or a t -table that the critical value -t0.05,14 is -1.7613. That is, we would reject the null hypothesis H0 : μ = 3 ... halton region demographics
F Test: Simple Definition, Step by Step Examples
WebSelect the appropriate test statistic. The test statistic is the F statistic for ANOVA, F=MSB/MSE. Step 3. Set up decision rule. The appropriate critical value can be found in a table of probabilities for the F distribution(see "Other Resources"). In order to determine the critical value of F we need degrees of freedom, df 1 =k-1 and df 2 =N-k. WebCommon test statistics. One-sample tests are appropriate when a sample is being compared to the population from a hypothesis. The population characteristics are known from theory or are calculated from the population.
