Question

What is a lurking​ variable?

Answer 1

Answer:

Option D

Step-by-step explanation:

When we study about relationship between two or more variables we sometimes ignore factors which affect the relationship other than these two variables. These are also called extraneous variables or lurking variables.  These affect the relationship very much.

Thus we find that out of 4 options given, Option I is incorrect because lurking variables need not be equal to almost 0.

Option B is incorrect because these need not have an infinite possible values.

Option C is a lurking variable need not be a response variable alone normally this would be an explanatory variable

Option D is right

A lurking variable is an explanatory variable that was not considered in a​ study, but that affects the value of the response variable in the study. In​ addition, lurking variables are typically related to explanatory variables in the study.
