2

What does a correlation quantify?

A correlation quantifies the strength and direction of a relationship between two measures.

3

Why is correlational research similar to naturalistic observation?

It is similar to naturalistic observation because we do not manipulate variables.

4

Why is correlational research different from naturalistic observation?

Correlational research is different from naturalistic observation because we always measure two variables and our plans for measurement are formalised prior to research.

5

Does correlation establish causality?

No

6

What two functions does correlation have?

1. Prediction is possible.
2. It can provide data that can be consistent or inconsistent with scientific theories.

7

What does differental research compare?

Differential research compares two or more groups that differ on pre-existing variables.

8

Does differential research manipulate variables?

No

9

Why is differential research similar to correlational research?

It does not manipulate variables.

10

What does differential and experimental research both utilise?

Groups defined by an independent variable.

11

When are differential methods most often used?

Differential methods are most often used when manipulation of a variable is impractical, impossible or impractible.

12

Whatis the ethical reasoning behind correlational and differential research?

Correlational and differential research can be used to provide useful ethical and practical information to shape action.

13

Can we draw on casual connections from correlational and differential research?

No. Correlational and differential methods are useful when we cannot use experimentation.

14

When are correlational and differential methods useful?

When we cannot use experimentation.

15

What is a particular problem in differential research?

Confounding variables.

16

What kind of psychologists often use differential research designs?

Developmental psychologists

17

When do we need to be weary of cohort effects?

In cross sectional designs.
