478: There is strong interaction between two variables. This means that:
A. An interaction occurs when the effect of one input factor on the output depends upon the level of another input factor
B. An interaction occurs when there is a strong correlation between two factors
C. An interaction occurs when the effect of one input factor on the output depends upon the level of the same input factor
D. An interaction occurs when two or more factors are confounded with each other
Correct option:
A. An interaction occurs when the effect of one input factor on the output depends upon the level of another input factor
Explanation:
An interaction occurs whenever the effects of one input factor on the output are not consistent for all levels of another input factor.

If there is an interaction between the independent variables textbook and time of day, this means that the textbook has the same effect at different times of the day. True or false?
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...
. An interaction can be best characterized as: a) When two IVs affect one another b) When the effect of an IV on a DV is conditional upon the level of another IV c) When the effect of an IV on a DV is unconditional upon the level of another IV d) The average effect of an IV on the DV, ignoring the other IV e) When the DV behaves differently for different IVs 4. The SSinteraction can be found...
If one gets a very small p value for a correlation between two variables, does it indicate a strong relationship between the two variables?
There is a(n) _______ between two factors if the effect of one of the factors changes for different categories of the other factor. - Variation. - Transformation. - Interaction. - Category Effect.
An interaction effect means that the combination of factors creates a different result. True False "A researcher conducts an experiment comparing four treatment conditions with n=12 scores in each condition. If the researcher uses a repeated-measures design, how many individuals are needed for the study?" a 12 b 24 c 36 d 48 "You have to find the F-critical for each effect when running a two-factor, independent measures, ANOVA. " True False "After you remove the individual differences in a...
1. Given three factors A, B, C the highest order interaction would be ABC. (a) True; (b) False. 2. What tools can be used to determine if factors have interaction? (a) Balanced ANOVA; (b) Standardized effects; (e) Interaction Plots; (d) Fractional factorial fits; (e) All of the above. 3. What does orthogonal mean? (a) One or more effects that cannot unambiguously be at- tributed to a single factor or factor interaction; (b) Involves running the experimental runs in random order;...
The covariance of two variables is: a) how they deviate from their means together b) how they deviate from their standard deviations together c) the total variance of both variables d) the percent of variance in one variable explained by another e) the squared differences from time 1 to time 2 If a researcher concludes that “decreases in self-esteem are strongly associated with decreases in social interaction” then what correlation coefficient describes her findings? a) .08 b) .87 c) -.87...
Is there GxE (gene-by-environment interaction) for the effects of sex in humans? Recall that GxE occurs where the effect of a given environmental change depends on an individual's genotype (for example, where a "better" environment is not equally better for all genotypes), or where the effect of a given genetic change depends on an individual's environment (for example, where a "taller" genotype adds a quantitatively different increment to the individual's expected height, depending on its environmental circumstances). In fact, these...
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
