If water amount also changes while testing the effect of fertiliser on plant growth what will water amount become?यदि पौधे की वृद्धि पर खाद का प्रभाव जांचते समय पानी की मात्रा भी बदल जाए तो पानी की मात्रा क्या बन जाएगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Confounding variableबाधक चर
Changing water amount may also affect growth so it becomes a confounding variable. Change only one main factor at a time.पानी की बदलती मात्रा भी वृद्धि को प्रभावित कर सकती है इसलिए यह बाधक चर बनेगी। एक समय में केवल एक मुख्य कारक बदलें।
