AP PSYCHOLOGY

Detailed explanation-1: -Correlational research involves measuring two variables and assessing the relationship between them, with no manipulation of an independent variable.

Detailed explanation-2: -Correlation Coefficient: A statistical measure of the extent to which two factors vary together, and thus how well either factor predicts the other.

Detailed explanation-3: -A correlational research design investigates relationships between variables without the researcher controlling or manipulating any of them. A correlation reflects the strength and/or direction of the relationship between two (or more) variables.

Detailed explanation-4: -Researchers use it to measure and spot historical patterns between two variables. A correlational study may show a positive relationship between two variables, but this can change in the future. Dynamic: The patterns between two variables from correlational research are never constant and are always changing.

Detailed explanation-5: -As we saw earlier in the book, an experiment is a type of study designed specifically to answer the question of whether there is a causal relationship between two variables. In other words, whether changes in an independent variable cause changes in a dependent variable.
