If you were intending to carry out a t-test on your independent sample design, which test might you do instead to compare participants' performance on your two experimental conditions, if the variance is not homogeneous?Question 4Answera.Welch's t-testb.Chi-squarec.Pearson's correlationd.A two-way ANOVA

In a two-sample t-test, there are two approaches: considering the equal variance and considering the unequal variance. What test is used to check if the variance of the two populations is equal or not?a.F testb.t testc.Z testd.Chi-square testClear my choice

We use an ANOVA instead of a t-test to analyse our data, in which circumstance?Question 13Answera.If our data does not meet the requirements of a parametric testb.If we want to test for a significant difference between our experimental conditions and there are more than two conditions to be comparedc.If we want to test for a correlation between the variables in our datasetd.when the independent variable is interval or ratio rather than nominal or ordinal

Which statistical test is commonly used to compare the means of two independent samples?a.t-testb.Analysis of Variance (ANOVA)c.Chi-square testd.Paired t-testClear my choice

At the beginning of the semester, students who registered for a statistics course were randomly assigned to two sections, each taught by a different instructor. At the end of the semester, we would like to test whether there are differences in performance on the final exam between the two sections.Which of the following is the most appropriate statistical test to use to test whether there are differences in performance on the final exam between the two sections? ANOVA Two-sample t-test Matched pairs t-test Inference for regression Chi-squared test for independence
