I’m not an expert, so use this as a last resort. I’m thinking d. A is to broad, B is just wrong, and C Canada has mostly provinces, not territories so that would be to limiting. The provinces don’t conduct their national affairs directly. Good luck, and hope that makes sense
Answer:
There are three main types of variables in a scientific experiment: independent variables, which can be controlled or manipulated; dependent variables, which (we hope) are affected by our changes to the independent variables; and control variables, which must be held constant to ensure that we know that,A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.There are six common variable types:
DEPENDENT VARIABLES.
INDEPENDENT VARIABLES.
INTERVENING VARIABLES.
MODERATOR VARIABLES.
CONTROL VARIABLES.
EXTRANEOUS VARIABLES.
Variable of interest, in an experimental study, a changing quantity that is measured. One or more of these variables, referred to as the factors of the study, are controlled so that data may be obtained about how the factors influence another variable referred to as the response variable, or simply the response.
