1. Describe a study where a one-way ANOVA would be appropriate (hint: how many independent variables are there in a one-way ANOVA?). Make sure to tell us your independent and dependent variables.
2. What would you hypothesize in terms of the effect of your IV on your DV on why?

1. Provide an example where a two-way ANOVA would be appropriate. Then, describe the hypothesized interaction effect (how does the effect of IV #1 depend on the effect of IV #2?).
Provide an example where a two-way ANOVA would be appropriate. Then, describe the hypothesized interaction effect (how does the effect of IV #1 depend on the effect of IV #2?).
Both the χ2 and the 1-way ANOVA allow one to study the effects of more than 2 levels of an independent variable on a dependent variable. Explain why we need the χ2 when we already have the ANOVA to handle more than one level of the independent variable. What does the χ2 allow us to do that the ANOVA does not?
QUESTION 44 In a two way ANOVA, how many effects (main effects and interaction) are tested? a. 4 b. 1 c. 3 d. 2 2 points QUESTION 45 Main effects are defined as the effect of ______. a. one independent variable on the dependent variable that changes at the different levels of another independent variable b. the dependent variable on the independent variable within a factorial research design c. an independent variable on the dependent variable within a factorial...
What would the levels of the independent variables be for a two-way ANOVA investigating the effect of four different treatments for depression and gender? Question 12 options: a) 4 and 1 b) 2 c) 4 and 2 d) 6
One-way analysis of covariance (ANCOVA) is similar to ANOVA but additionally controls for a variable that may influence the DV. T F Factorial analysis of variance (factorial ANOVA) extends ANOVA to research scenarios with two or more IVs that are categorical. T F Factorial analysis of variance (factorial ANCOVA) examines group differences in a single quantitative dependent variable based upon two or more categorical independent variables, while controlling for a covariate that may influence the DV. T F One-way multivariate...
We make many decisions throughout our day based on probability. What is an example of something from your daily life that you choose based on how likely it will happen? How would the probability need to change for you to make a different decision? 1. Hypothesis testing is based on the idea that if there is enough of a difference between your experimental sample and the comparison distribution, you can see the research supports your hypothesis. Describe an experiment in...
You have been hired as a consultant for technology company. Create a study which would look into ways that would increase productivity for this company using a one-way ANOVA. What is your IV? What is your DV? How many levels of your IV are there and what are they?
a.What is a One-Way ANOVA? b. What is the dependent variable? c. What are the factor variables? d. Design levels________ levels Store size ___________levels e. To find out the differences in design, what tool would you use within SPSS? f. When is Tukey appropriate to use? g. What is used for a small number of comparisons? h. What does the ANOVA table exhibit? i. What are linear trends? j. Overall, why is ANOVA needed?
Problem Set 1: Two-way ANOVA (8 pts) Research Scenario An Industrial/Organizational psychologist conducted a study examining differences in sex (women and men) and preferred method (face or email) on likelihood of negotiating a raise in the next 6 months. Likelihood was measured using percent probability (where 0 indicates absolutely not planning to negotiate a salary and 100 indicates definitely planning to negotiate a salary in the next 6 months). Twenty-seven participants completed the study. Their results are in the table...
