Expert Solution

One-Way ANOVA: An ANOVA hypothesis tests the difference in population means based on one characteristic or factor. a----->b "An example of when a one-way ANOVA could be used is if you want to determine if there is a difference in the mean height of stalks of three different types of seeds. Since there is more than one mean, you can use a one-way ANOVA since there is only one factor that could be making the heights different. "

Two-Way ANOVA: An ANOVA hypothesis tests comparisons between populations based on multiple characteristics. a---->c<----b "Suppose that there are three different types of seeds, and the possibility that four different types of fertilizer is used, then you would want to use a two-way ANOVA. The mean height of the stalks could be different for a combination of several reasons" Multivariate analysis of variance (MANOVA): it is simply an ANOVA with several dependent variables. That is to say, ANOVA tests for the difference in means between two or more groups, while MANOVA tests for the difference in two or more vectors of means. a----->c, b------>d, a----->d, b----->c

Why is ANOVA more appropriate than multiple t-tests when comparing more than two groups?

Traditional ANOVA is usually used when our categorical predictor variable has more than two categories. It works for two categories, it's just that there is a simpler technique for that -- two-sample t. To show ANOVA works for two categories, see if pulse rate before depends on Sex.

A t ratio compares two means and the ANOVA compares more than two means. Why is ANOVA used rather than a series of t tests? It holds type I error at a constant level It increases Type I error It is too much work to do a series of t tests Both methods provide the same information

Explain (in no more than two paragraphs for each) which of the following statements are true or false. A. The traditional liquidity premium theory states that long-term interest rates are greater than the average of current and expected future short-term interest rates .B. According to the market segmentation theory, short-term investors will not normally switch to intermediate- or long-term investments. C. According to the liquidity premium theory, investors preferring long-term bonds over short-term bonds would require lower liquidity premium.

4) Explain (in no more than two paragraphs for each) which of the following statements are true or false. A. Suppose two bonds of equivalent risk and maturity have different prices such that one is a premium bond and one is a discount bond. The premium bond must have a greater expected return than the discount bond. B. All else equal, the holder of a fairly priced premium bond must expect a capital loss over the holding period. C. The...

A repeated measures ANOVA is statistically more powerful than a randomized ANOVA. One reason is that the same subjects are used (like a paired t test). Why else? The within source of variance in a randomized ANOVA becomes ___subject______ and __error________in a repeated measures ANOVA. Only the __error_____ is used to calculate the F ratio. Because the denominator is smaller, the F ratio will be ___?____ and more likely to ______?_________ . Hints: error, fail to reject the null hypothesis,...

When an independent variable has more than three levels, why should you conduct an ANOVA and post-hoc testing instead of just multiple t-tests?

Explain ANOVA (Analysis of Variance). How is F test for differences among more than two means used in this case to test a hypothesis? Give an example.

a. When is a two-way, within-subjects ANOVA performed? b. When is a two-way, mixed-design ANOVA performed?

When the relationship between two or more independent variables needs to be tested, a common tool...

When the relationship between two or more independent variables needs to be tested, a common tool to use is a regression analysis. Take, for example, a study that shows the relationship between gaming and teen violence or a study that shows a correlation between fast-food eating habits and obesity. Complete the following for this assignment Describe 2–3 combinations of independent and dependent variables that you could test using a regression analysis. What types of results could the regression analysis yield?...
