How many variables may be tested legitimately in any one experiment?
I think it's very difficult to answer this question simply. Depending on the sophistication of your research model and the amount of data and the accuracy with which the research is carried out, you can test several variables simultaneously. This can be done 'legitimately', and sometimes it is too costly to run research projects that test one or two variables at a time. Some of these complex and sophisticated statistical models are used very infrequently, but it can be done.
In a properly designed experiment how many mainpulated responding and controlled variables should you have why?
In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
What is ex-post-facto design?
Ex Post Facto (also called Causal Comparative Research) is useful whenever: • We have two groups which differ on an independent variable and we want to test hypotheses about differences on one or more dependent variables OR • We have two groups which already differ on a dependent variable and we want to test hypotheses about differences on one or more independent variables
How many dependent variables should you have?
The number of dependent variables you should have depends on the research question and the complexity of the study. In general, it's advisable to focus on one or two primary dependent variables to maintain clarity and coherence in your analysis. Having too many dependent variables can complicate interpretation and may lead to issues with statistical power. However, if your study is designed to explore multiple outcomes, ensure that each variable is theoretically justified and relevant to your hypothesis.
What are the two variables that are important in momentum?
The two important variables in momentum are the mass of the object and its velocity. Momentum is calculated by multiplying an object's mass by its velocity.
How to conduct a 2x2 analysis in research methodology?
To conduct a 2x2 analysis in research methodology, you need to categorize your data into two groups each with two variables. Then, you compare the groups to see if there are any significant differences or relationships between the variables. This type of analysis is commonly used in experimental research to examine the effects of two independent variables on a dependent variable.

What is cor-relational research?
Correlation Research Method, a statistical measure of a relationship between two or more variables, gives an indication of how one variable may predict another.
What is co relational research?
Correlational research is a type of non-experimental research design that examines the relationship between two or more variables without manipulating them. It seeks to determine if there is a statistical relationship between the variables, but does not imply causation. Correlational studies provide information about how variables are related and can help generate hypotheses for further research.
What are two research methods widely used by psychologists?
Two widely used research methods in psychology are experiments, which involve manipulating variables to observe their effects on behavior, and surveys, which involve collecting self-reported data from participants to analyze relationships between variables.
What is correlational research method?
Correlational research method is a type of study that looks at the relationship between two or more variables in order to determine if and how they are related. It involves measuring the variables as they naturally occur without manipulating them. Correlational studies can provide valuable insights into potential relationships between variables but cannot establish causation.
How can descriptive and comparative methods explain research collections?
descriptive-comparative methods of research is a way where we can normally predict the significance and difference of the two variables.
When is a correlation research method used?
A correlation research method is used to examine the relationship between two variables to see if they are related and how they may change together. It helps to determine if there is a pattern or connection between the variables, but it does not imply causation.
What is research methodology?
this method provides an explanation about the extent of relationship between two or more variables. it examines the relationships including similarities or differences among several variables.
How does experimental research differ importantly from correlational research methods?
how does experimental research differ importantly from correlational research methods Correlational Research are predictions and are mostly based on statistics. Whereas Experimental Research is based on experiment and explaination.
What does an experiment show when it show that two variables are closely related?
When an experiment shows that two variables are closely related, it suggests that changes in one variable are associated with predictable changes in the other variable. This can indicate a causal relationship between the variables, where one variable directly influences the other. However, it is important to consider other factors and conduct further research to establish a robust understanding of the relationship.
