False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.
Direct Cost are those costs that can be directly assigned to a production process. Indirect cost were those costs that cannot be directly assigned to production process but have to allocate to production. Variable costs are those costs that vary directly with the production level. Only Direct cost could be variable . But not all direct cost are variable. Thus direct cost contains both Variable and Fixed elements while indirect costs contains only fixed element.
T
A variable does and must change, but you can only have one variable, otherwise the experiment becomes biased and unfair

False: they are called exogenous.
false
False. A dependent variable is a factor in an experiment that is being measured or observed and is influenced by the independent variable. It is used to determine the effect of changes made to the independent variable.
False. The factor that may change in response to the manipulated variable is called the "dependent variable," while the manipulated variable is referred to as the "independent variable." The dependent variable is what researchers measure to see the effect of changes made to the independent variable.
