What Is A Causality Study?
A causality study is a research method that investigates the relationship between variables to determine if a change in one variable causes a change in another. These studies aim to establish cause-and-effect relationships through controlled experimentation or statistical analysis. The goal is to determine if there is a direct impact between the variables being studied.
What is a relational study?
A relational study is a research method that examines the relationships between two or more variables to determine how they are connected or associated. These studies often involve analyzing data to identify patterns, correlations, or causal relationships between the variables being studied. The goal is to gain insight into how changes in one variable may affect another.
What are two types of mathematical relationships that exist between different variables?
Direct or inverse relationships,that is a problem
Uses bars to show the relationships between variables?
A Bar Graph!
What are interfering variables?
An intervening variable is a hypothetical internal state that is used to explain relationships between observed variables
This is the type of research that describes the strength and direction of relationships between variables?
Correlational
Does Cross-sectional study measure relationships between disease and other variables?
They can do.
What is correlatational study?
A correlational study is a research method that examines relationships between variables without manipulating them. It aims to determine if and to what extent a relationship exists between two or more variables, but it does not establish causation. The strength and direction of the relationship are typically measured using statistical techniques such as correlation coefficients.
How can one effectively interpret a regression table?
To effectively interpret a regression table, focus on the coefficients, standard errors, and significance levels. Coefficients show the relationship between variables, standard errors indicate the precision of the estimates, and significance levels determine if the relationships are statistically significant. Look for patterns, consider the context, and use the information to draw conclusions about the relationships between variables.

Which variable can you control?
You can control independent variables in an experiment. These are factors that you deliberately change in order to observe their effect on dependent variables, which are the outcomes you are measuring. By controlling independent variables, you can help determine cause-and-effect relationships.
