Experimental Research Methods

The most used method for gathering subjects into equivalent groups in experimental research is randomization, which ensures that the groups are similar in all aspects except for the independent variable.

Importance of Two Groups

The need for two groups, an experimental group and a control group, is important in experimental research because it allows researchers to compare the effects of the independent variable on the dependent variable.

Independent Variable Manipulation

The manipulation of independent variables involves intentionally changing the independent variable to observe its effect on the dependent variable, while controlling for other variables.

Inferential Statistics

Inferential statistics allow researchers to make inferences about the population based on the sample data, and to determine whether the results are due to chance or the effect of the independent variable.

Purpose of Equivalent Groups

The purpose of gathering subjects into equivalent groups is to control for extraneous variables and to ensure that the groups are similar in all aspects except for the independent variable.

Role of Independent Variable

The independent variable is manipulated by the researcher to observe its effect on the dependent variable.

Purpose of Random Allocation

The purpose of random allocation of subjects is to minimize bias and ensure that the groups are equivalent.

Comparing Conditions

Experimental research involves comparing the conditions of the experimental and control groups to determine the effect of the independent variable.

Role of Inferential Statistics

The role of inferential statistics is to analyze the data and determine the significance of the results.
