In ANCOVA there should be one covariate fewer than the number of independent variables. True False
Homework Answers
Answer:-
- A covariate can be an independent variable.
- Actually adding a covariate to a model will definitely increase the results with high accuracy.
- In ANCOVA , the number of covariates should be minimum is a good idea.
- No,In ANCOVA there should be one covariate fewer than the number of independent variables.
- So the answer is FALSE.

The primary factor that determines the statistical test students should use is the number of independent and dependent variables. True or False When investigating the relationship between two or more quantitative variables, chi-square is the appropriate test.True or False The Pearson correlation coefficient measures the association between two quantitative variables, distinguishing between the independent and dependent variables.True or False Multiple regression is used when there are several dependent variables and one independent quantitative variable.True or False When testing for the...

What makes ANCOVA different from ANOVA? a. ANCOVA can include dummy variables. b. ANCOVA can include one or more continuous variables that predict the outcome. c. ANCOVA can include continuous variables that are not part of the main experimental manipulation but influence the dependent variable. d. ANCOVA can include continuous variables that are not part of the main experimental manipulation but influence the independent variable.

Wesley has generated an ANCOVA. In his model, there is one independent variable which has 3 categories (type of phone: Blackberry, iPhone, and Droid) and one covariate (amount of time spent on desktop or laptop computer). In testing the assumptions, he reviews a one-way ANOVA, the dependent variable being amount of time spent on desktop or laptop computer and the independent variable being type of phone. For which assumption is Wesley likely reviewing evidence? A. Homogeneity of regression slopes B....

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...

TRUE OR FALSE: We cannot avoid multicollinearity in a multiple regression as the independent variables are always correlated with each other to some extent? Perfect multicollinearity means independent variables are - perfectly correlated - positively correlated - highly correlated - not correlated Near multicollinearity means independent variables are - perfectly correlated - positively correlated - highly correlated - not correlated
