In a research analysis the variable whose variation is being studied is the
Dependent variable
Because in research analysis we study the variation of dependent variable by the relation with independent variable.
Add Answer to:

An independent variable is a. how accurately a measure yields information about the true or real variable being studied b. determined by other variables in the study ; also known as the outcome variable c. used to explain or predict the outcome of interest ; also known as the predictor variable d. a process of data collection and analysis ; reflects the overall quality of the research process
Which of the following is a true statement? Regression analysis and ANOVA are similar tools because they both determine if an independent variable has an effect on a quantitative dependent variable
Which of the following is a true statement? Regression analysis and ANOVA are similar tools because they both determine if an independent variable has an effect on a quantitative dependent variable, but in ANOVA the independent variable is qualitative and in Regression analysis the independent variable in quantitative. Regression analysis and ANOVA are similar tools because they both determine if a qualitative independent variable has an effect on a quantitative dependent variable. Regression analysis and ANOVA are similar tools because...

Question 2 1 pts The goal of regression is to see O if the independent variable(s) can explain the variation in the control variable(s). if the dependent variable(s) can explain the variation in the control variable(s). O if the independent variable(s) can explain the variation in the dependent variable(s). O if the dependent variable(s) can explain the variation in the independent variable(s).
In controlled comparison research, the observed relationship between an independent variable (X) and a dependent variable...
In controlled comparison research, the observed relationship between an independent variable (X) and a dependent variable (Y) may be caused by some other, uncontrolled compositional difference (Z). So, we always ask, “How else, besides the independent variable, are the groups I am comparing not the same?” For the hypothesis below, do the following: (i) Think up a plausible alternative causal variable. (ii) Describe how this variable might affect the relationship between the independent variable and the dependent variable. In a...
