AP PSYCHOLOGY

Detailed explanation-1: -An independent measures design is a research method in which multiple experimental groups are used and participants are only in one group. Each participant is only in one condition of the independent variable during the experiment. An example would be a drug trial for a new pharmaceutical.

Detailed explanation-2: -Independent measures design, also known as between-groups, is an experimental design where different participants are used in each condition of the independent variable. This means that each condition of the experiment includes a different group of participants.

Detailed explanation-3: -Independent groups are more common in hypothesis testing. For example, the following experiments use independent samples: A medication trial has a control group and a treatment group that contain different subjects. A study assesses the strength of a part made from different alloys.

Detailed explanation-4: -An independent-measures study uses a separate group of participants to represent each of the populations or treatment conditions being compared.

Detailed explanation-5: -There are three different types of independent groups designs: – random groups designs, – matched groups designs, and – natural groups designs. Individuals are randomly assigned to the different conditions of the independent variable.
