Detailed explanation-1: -Researchers often include multiple independent variables in their experiments. The most common approach is the factorial design, in which each level of one independent variable is combined with each level of the others to create all possible conditions.
Detailed explanation-2: -To design a controlled experiment, you need: A testable hypothesis. At least one independent variable that can be precisely manipulated. At least one dependent variable that can be precisely measured.
Detailed explanation-3: -In an experiment, the researcher varies (or manipulates) one or more independent variables. An independent variable must have two or more levels (different values). These levels can reflect either quantitative or qualitative differences in the independent variable.
