Question

For an F-value to be significant, it must A. positive B. equal 1.0 C. exceed the tabled value D. be less than the tabled value When we say that a correlation coefficient is statiscally significant, we mean that A. we have reason to believe it reflects an important relationship between variables B. we have reason to believe that the relationship is positive C. We have reason to believe that the true correlation in the population is not 0.0 D. we have strong support for a causal statement about the relationship The most common level of a when running a chi-square goodness-of-fit test is A. .05 B. .01 C. .05/E D. .95 When looking at multiple comparisons, more tests that you run, the more likely that you will the commit a _____. A. Type I error B. Type II error C. mean squared error D. random error A typical null hypothesis with a goodness-of-fit test as presented in the text might be A. the hypothesis that the means increase evenly across categories B. the hypothesis that the representation in each category is equal C. the hypothesis that subjects are normally distributed D. the hypothesis that the expected values are uniformly large To look at an interaction effect we must A. consider one variable at a time B. plot the means from each level of one independent variable C. plot the data in such a way that we see how each independent variable changes at each level of the other independent variable D. calculate the row means In the analysis of variance we will assume that A. the populations are normally distributed B. the populations follow a rectangular distribution C. the populations all have completely different shapes D. there is no assumption about the shape of the population

Explanation / Answer

8. The F critical value is what is referred to as the F statistic. In general, if your calculated F statistic in a test is larger than your table F value, you can reject the null hypothesis. However, the statistic is only one measure of significance in an F Test.

i.e. If F value < F table value it is significant

So answer is D.
