Interactions:
a. |
occur when the effect of one factor on the dependent variable is independent of the level of other factors |
|
b. |
occur only in one-way ANOVA tests |
|
c. |
indicate the effect of one factor on the dependent variable is the same regardless of the level of the other factors |
|
d. |
indicate patterns of differences in means that could not be guessed from the main effects alone |
option D is correct
indicate patterns of differences in means that could not be guessed from the main effects alone
(or if effect of one factor on the dependent variable is dependent on the level of other factors)
Interactions: a. occur when the effect of one factor on the dependent variable is independent of...
Lesson: -Factorial designs have more than one independent variable or factors. -A two way factorial design has two independent variables, a three-way factorial design has three independent variables and so forth. -A 2x2 design has two factors and two levels of each. -A 2x3 design also has two factors but one has two levels and one has three. -A 3x3 design has two factors and each factor has 3 levels. Each example has 2 independent variables or factors. Comparison of...
Aa Aa 11. Two-factor ANOVA Emphasis on calculations W.Thomas Boyce, a professor and pediatrician at the University of British Columbia, Vancouver, has studied interactions between individual differences in physiology and differences in experience in determining health and well-being. Dr. Boyce found that some children are more sensitive to their environments. They do exceptionally wel when the environment is suppo「tive but are much more likely to have mental and physical health problems when the environment has challenges. You decide to do...
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?
1. An analysis of variance with one dependent and one independent variable is referred to as: A) one-way ANOVA B) two-way ANOVA C) many-way ANOVA D) correlation 3. What is the null hypothesis when using ANOVA? A) B) C) D) 4. What is the research hypothesis when using ANOVA procedures? A) all of the group means are equal B) all of the group means are significantly different from all other group means C) at least one of the group means is significantly different from...
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...
