Can you have three dependent variables?
Researchers in psychology often include multiple dependent variables in their studies. The primary reason is that this easily allows them to answer more research questions with minimal additional effort.
Can a research have 3 variables?
Just as it is common for studies in psychology to include multiple dependent variables, it is also common for them to include multiple independent variables.
Is it OK to have multiple dependent variables?
It is called dependent because it “depends” on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable. It is possible to have experiments in which you have multiple variables. There may be more than one dependent variable and/or independent variable.
How many dependent variables are there in research?
A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.
How many levels can a dependent variable have?
A dependent variable can definitely be categorical and have multiple levels. These levels may be ordinal or not (briefly, it is ordinal if the levels have a definite order – e.g. none, some, a lot). If the dependent variable is ordinal, one choice is ordinal logistic regression.
How many dependent variables can you have?
What are the three levels of independent variables?
You can think of a “level” as a sub type of the IV. For example, you might be studying weight loss for three different diets: Atkins, Paleo, and Vegan. The three diets are the three levels of Independent Variable. Or, you could have an experiment where you are comparing two treatments: placebo and experimental.
How are independent and dependent variables used in research?
Techniques include associations, sampling, random selection, and blind selection. Designation of the dependent and independent variable involves unpacking the research problem in a way that identifies a general cause and effect and classifying these variables as either independent or dependent. The variables should be outlined in
When to use student’s ttest, analysis of variance, and ANCOVA?
Student’s ttest (ttest), analysis of variance (ANOVA), and analysis of covariance (ANCOVA) are statistical methods used in the testing of hypothesis for comparison of means between the groups. For these methods, testing variable (dependent variable) should be in continuous scale and approximate normally distributed.
Which is a technique for classifying a dependent variable?
Techniques include associations, sampling, random selection, and blind selection. Designation of the dependent and independent variable involves unpacking the research problem in a way that identifies a general cause and effect and classifying these variables as either independent or dependent.
How many causal paths does an independent variable have?
Your independent variable would have three directed (causal) paths to each of the 3 dependent variables. The residuals of the dependent variables would have covariance paths among them defined to account for correlations.
