Experimental Research

Introduction

This video will explain the concept of experimental research.
The study of experimental research will focus on its causes and characteristics.

There are two types of variables in experimental research:
- Independent Variables: There can be one or more.
- Dependent Variables: There can also be one or more.
In this, the researcher manipulates the independent variables and observes the effect of this manipulation on the dependent variables.

Sugar Intake and Weight:
- If sugar intake is high, does weight increase?
- If sugar intake is decreased, does weight decrease?
- Here, sugar intake is the independent variable (cause) and weight is the dependent variable (effect).

Experimental research studies the relationship between cause and effect.
The independent variable is the cause, and the dependent variable is the effect.

It is commonly used in education, psychology, social sciences, and physical sciences.
Experimental research is based on observation, calculation, comparison, and logic.

The focus of experimental research is to determine what effect occurs on a dependent variable if the independent variable is changed.

Advertisement and Sales:
- If a company advertises its product, do sales increase?
- How much change occurs in sales?

Manipulation:
- The researcher manipulates the independent variable.
- Without manipulation, it would not be called experimental research.
Full Control on Experiments:
- The researcher has full control over the experiments.
- The effects of extraneous variables are controlled or eliminated.
- Extraneous variables are those that are not part of the research.
Effect Calculation:
- The effect of the independent variable on the dependent variable is calculated.
- It is observed what effect occurs on the dependent variable due to manipulation.

There are three main characteristics of experimental research: manipulation, full control, and effect calculation.
