What are the three essential characteristics of experimentation?

The three essential characteristics of experimentation are manipulation, control, and randomization. Manipulation involves deliberately changing one or more variables to observe the effect on a dependent variable. Control refers to the ability to eliminate or account for extraneous factors that could influence the results, ensuring that the observed effects are due to the manipulated variables. Randomization helps to ensure that participants are assigned to different conditions in a way that minimizes bias, enhancing the reliability and generalizability of the findings.
