What is the primary difference between an experiment and an observastional study?
The primary difference is that in an experiment, the researcher actively manipulates or controls one or more variables to observe the effect on another variable, while in an observational study, the researcher simply observes and records data without intervening or controlling any variables. Experiments allow for more control over variables and can establish cause-and-effect relationships, while observational studies can only establish correlations.

What is the difference between continuous and discrete system?
The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.
What is significant difference?
A significant difference refers to a statistically meaningful distinction between two or more groups or variables. It implies that the difference observed is unlikely to have occurred by chance and is likely to have practical relevance. Statistical tests are used to determine if a difference is significant.

What is multiple correlation coefficient and partial correlation coefficient?
partial correlation is the relation between two variable after controlling for other variables and multiple correlation is correlation between dependent and group of independent variables.
What is the difference between experimental and ex post facto research?
Ex-post facto research measures the cause and effect relationship without manipulating the independent variable. While the experimental research starts from manipulating and controlling the independent variables and proceeds to observing the effect on the dependent variables.
What is the difference between experimental and ex post facto research design?
Ex-post facto research measures the cause and effect relationship without manipulating the independent variable. While the experimental research starts from manipulating and controlling the independent variables and proceeds to observing the effect on the dependent variables.
What is the difference between variables and rules?

What is the difference between control system and controller?
