Detailed explanation-1: -Correlation is a statistical tool that shows the association between two variables.
Detailed explanation-2: -Comparative research questions aim to discover the differences between two or more groups for an outcome variable. These questions can be causal, as well. For instance, the researcher may compare a group where a certain variable is involved and another group where that variable is not present.
Detailed explanation-3: -c) The statement “The correlation indicates the strength and the direction of the linear relationship between two variables” is correct as it is the basic definition of it.
Detailed explanation-4: -The experimental method features the manipulation of an independent variable, the measurement of a dependent variable, and control of extraneous variables. The manipulation of ‘independent variable’ and control of ‘extraneous variables’ is quite impossible in the Ex post facto method.
