Control and randomization techniques are super important for making psychological research repeatable. Here are the main points:
Keeping Things the Same: By keeping certain elements constant, researchers can focus on the effects of one specific factor. This helps keep the results more steady and clear.
Random Assignment: By placing participants into groups randomly, researchers can avoid bias. For example, in a study with 100 people, random assignment can create two equal groups (50 in each) that are similar.
Stronger Results: Good control methods make it easier to find real effects in research. Usually, a study needs at least 30 participants in each group to have a good chance (80%) of finding these effects.
Using these techniques can really help with the reproducibility crisis in psychology. This is when it’s hard to repeat studies and get the same results.
