|
make it difficult to isolate and evaluate the impact of the independant variable.

Detailed explanation-1: -A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
Detailed explanation-2: -Answer and Explanation: The correct answer is c. extraneous. These variables may affect the dependent variables of interest, but they are not the independent variables that the scientist will control or manipulate.
Detailed explanation-3: -The independent variable, also known as the manipulated variable, is the factor manipulated by the researcher, and it produces one or more results, known as dependent variables.
Detailed explanation-4: -The experimental method features the manipulation of an independent variable, the measurement of a dependent variable, and control of extraneous variables.
