RESEARCH METHODOLOGY

Detailed explanation-1: -In a nomothetic causal relationship, the independent variable causes changes in a dependent variable. Hypotheses are statements, drawn from theory, which describe a researcher’s expectation about a relationship between two or more variables.

Detailed explanation-2: -Answer and Explanation: A causal relationship exists between variables when a change in one variable results in the occurrence of a change in the other variable. The former is known as the cause, and the latter is the effect.

Detailed explanation-3: -What is causal research? Causal research is also known as explanatory research. It’s a type of research that examines if there’s a cause-and-effect relationship between two separate events. This would occur when there is a change in one of the independent variables, which is causing changes in the dependent variable.

Detailed explanation-4: -In causal-comparative research, the researcher investigates the effect of an independent variable on a dependent variable by comparing two or more groups of individuals. For example, an educational researcher may want to determine whether a computer-based ACT program has a positive effect on ACT test scores.
