A variable does and must change, but you can only have one variable, otherwise the experiment becomes biased and unfair
True. An independent variable is the factor that is intentionally manipulated or changed by the researcher in an experiment to observe its effect on a dependent variable. This distinction allows for the investigation of causal relationships between variables.
True. In a scientific experiment, the manipulated variable, also known as the independent variable, is the one that is intentionally changed or controlled by the researcher to test its effect on the dependent variable. This allows scientists to observe how changes in the manipulated variable influence the outcome of the experiment.
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.
False- The hypothesis is your prediction of what you expect to happen. If the data does not agree with your hypothesis you simply explain why your hypothesis did not come true and possibly investigate variable which would allow your hypothesis to come true.
False.
true or false : in order to get the best results from an experiment, change as many variables as possible within the experiment?
false
True.
False. In an experiment, a constant refers to a factor that does not change, while the variable being measured is typically called the dependent variable. The constant helps ensure that the experiment tests the effect of the independent variable on the dependent variable without interference from other factors.
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.

In a statistics experiment, the dependent variable is the event studied and expected to change whenever the independent variable is altered.So, yes, the IV can change when required.
The claim that the fleas in a jar experiment is true is false.
