four-variable experimenthalf-normal plotstandard deviationFactorial experiments are efficient in obtaining accurate estimates of an effect. This chapter looks at both a 23 and 24 experiment that demonstrates the
In an experiment, the variable being controlled is called theindependent variable. It is attributed as the cause of change, which an experimenter can manipulate. In an experiment about a fertilizer's effect on plant growth, the independent variable is the fertilizer because it is manipulated. Anot...

What is the control in an experiment? A control in a science experiment is a sample that is not affected by changes occurring from the independent variable. It is meant to establish the validity of the experiment. How do you find the control in an experiment? You find the control in an ...
The meaning of INDEPENDENT VARIABLE is a mathematical variable that is independent of the other variables in an expression or function and whose value determines one or more of the values of the other variables.
If an experiment were comparing five types of diets, then the independent variable (type of diet) would have 5 levels. In general, the number of levels of an independent variable is the number of experimental conditions. Qualitative and Quantitative Variables...
