Which of the following approach should be used if you can’t fix the variable?

randomize it
non stratify it
generalize it
none of the mentioned

The correct answer is: A. randomize it

If you can’t fix the variable, you should randomize it. This means that you should assign the variable to different values in a random way. This will help to ensure that the results of your study are not biased.

Option B, non stratify it, is incorrect. Stratifying a variable means dividing it into different groups. This is not necessary if you can’t fix the variable.

Option C, generalize it, is incorrect. Generalizing a variable means making it more general. This is not necessary if you can’t fix the variable.

Option D, none of the mentioned, is incorrect. Randomizing the variable is the best way to deal with a variable that you can’t fix.
