Question 1/3 Medium Science Exploration: Entering the World of Secondary Science Variables in an experiment Class 9 Level 10

स्वतंत्र आश्रित और नियंत्रित चरों के संबंध का सबसे सही वर्णन कौन सा है?

Which statement best describes the relationship among independent dependent and controlled variables?

Explanation opens after your attempt
Correct Answer

B. स्वतंत्र चर बदला जाता है आश्रित चर मापा जाता है और नियंत्रित चर समान रखे जाते हैंThe independent variable is changed the dependent variable is measured and controlled variables are kept constant

Step 1

Concept

The independent variable is the possible cause and the dependent variable is the outcome. Controlled variables ensure a fair comparison.

Step 2

Why this answer is correct

The correct answer is B. स्वतंत्र चर बदला जाता है आश्रित चर मापा जाता है और नियंत्रित चर समान रखे जाते हैं / The independent variable is changed the dependent variable is measured and controlled variables are kept constant. The independent variable is the possible cause and the dependent variable is the outcome. Controlled variables ensure a fair comparison.

Step 3

Exam Tip

स्वतंत्र चर संभावित कारण और आश्रित चर परिणाम होता है। नियंत्रित चर निष्पक्ष तुलना सुनिश्चित करते हैं।

Question 3/3 Easy Science Exploration: Entering the World of Secondary Science Variables in an experiment Class 9 Level 11

स्वतंत्र आश्रित और नियंत्रित चर का सही संबंध क्या है?

What is the correct relationship among independent dependent and controlled variables?

Explanation opens after your attempt
Correct Answer

A. स्वतंत्र चर बदला जाता है आश्रित चर मापा जाता है और नियंत्रित चर समान रखे जाते हैंThe independent variable is changed the dependent variable is measured and controlled variables are kept the same

Step 1

Concept

The independent variable is changed as the cause and the dependent variable is measured as the outcome. Controlled variables maintain fairness.

Step 2

Why this answer is correct

The correct answer is A. स्वतंत्र चर बदला जाता है आश्रित चर मापा जाता है और नियंत्रित चर समान रखे जाते हैं / The independent variable is changed the dependent variable is measured and controlled variables are kept the same. The independent variable is changed as the cause and the dependent variable is measured as the outcome. Controlled variables maintain fairness.

Step 3

Exam Tip

स्वतंत्र चर कारण के रूप में बदला जाता है और आश्रित चर परिणाम के रूप में मापा जाता है। नियंत्रित चर निष्पक्षता बनाए रखते हैं।
