Direction : Carefully read the following information to answer Q.no.1 and Q.no.2
An egg farmer is experimetnting with different feed rations with the aim of increasing his production whilst reducing the cost of the feed per egg produced. The data from two feeding experiments is given below.

What are the independent variable in each of the two experiments?

Options

A. `{:("Experiment 1",,"Experiment 2"),("Maximum daily egg production",,"Maximum daily egg production"):}`
B. `{:("Experiment 1",,"Experiment 2"),("Protein concentration in the feed",,"Total vitamin level in the feed"):}`
C. `{:("Experiment 1",,"Experiment 2"),("Total vitamin level the in the feed",,"Protein concentration in feed"):}`
D. `{:("Experiment 1",,"Experiment 2"),("Cost of feed ration per egg produced",,"Cost of feed ration per egg produced"):}`

Answer

B

Explanation

Variable used to an experiment can be dependent variables or independent variables. The 'dependent variable' represents the output or effect, or is tested to see if it is the effect. The 'independent variable' represents the inputs or causes, or are tested to see if it is the cause. Here, in experiment 1 protein concentration in the feed is independent variable while in experiment 2, total vitamin level in the feed is independent variable.
