What is the independent variable of the statement above?
A
Height of grass
B
Amount of nitrogen
C
Essential nutrient
D
Amount of growth
Explanation: 

Detailed explanation-1: -Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.

Detailed explanation-2: -The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words “IF” and “THEN.” For example, “If I do not study, then I will fail the test.” The “if’ and “then” statements reflect your independent and dependent variables.

Detailed explanation-3: -Analyze Your Data and Draw a Conclusion Once your experiment is complete, you collect your measurements and analyze them to see if they support your hypothesis or not.
