Identify the dependent variable in the following study. "Effect of computer Assisted Instruction on the learning of Tamil Grammar of IX standard students of Tamilnadu".
Dependent Variable Identification in Educational Research
In any research study, understanding the different types of variables is crucial. Variables are factors that can change or vary. In experimental research, we often distinguish between the independent variable and the dependent variable.
- Independent Variable (IV): This is the variable that the researcher manipulates or changes. It's the presumed cause or factor being tested.
- Dependent Variable (DV): This is the variable that is measured or observed. It's the outcome or effect that is expected to change in response to the manipulation of the independent variable.
Analyzing the Study Variables
Let's break down the specific study described: "Effect of computer Assisted Instruction on the learning of Tamil Grammar of IX standard students of Tamilnadu".
The study aims to see if one thing (Computer Assisted Instruction) has an impact on another (learning Tamil Grammar). The students involved are specifically "IX standard students of Tamilnadu".
- Independent Variable: The factor being manipulated or introduced is Computer Assisted Instruction. The researchers are likely comparing students who receive CAI to those who don't, or comparing different methods of CAI.
- Dependent Variable: The outcome being measured to see if it changes because of the CAI is the learning of Tamil Grammar. This could be measured through tests, scores, or other assessments of grammar knowledge and skills.
- Population: The study focuses on IX standard students in Tamilnadu.
Therefore, the factor whose change is being measured or observed is the learning of Tamil Grammar, making it the dependent variable.
Important Questions from Variables
Given below are two statements:

Given below are two statements: one is labelled as Assertion A and other is labelled as Reason R
Assertion A: Experimental research allows you to eliminate the influence of many extraneous factors.
Reason R: In experimental research variables are actively manipulated and environment is as controlled as possible
