Note: If more than $13,000 of debt is canceled in one year, the gift giver has to file a gift tax return (although they almost certainly will not owe a tax). That should not affect you as the recipient. Example: Roxy borrowed $6,000 from her dad while she was unemployed. She wrote up a promissory note for the debt.
Control Group and Experimental Group. True experiments must have a control group, which is a group of research participants that resemble the experimental group but do not receive the experimental treatment. The control group provides a reliable baseline data to which you can compare the experimental results.
Generally, one or more variables are manipulated to determine their effect on a dependent variable. The experimental method. is a systematic and scientific approach to research in which the researcher manipulates one or more variables, and controls and measures any change in other variables. Experimental Research is often used where: 1  There is time priority in a causal relationship (cause precedes effect). 2  There is consistency in a causal relationship (a cause will always lead to the same effect). 3  The magnitude of the correlation is great.
