What is a treatment variable in biology?
In this scenario, the variables are the treatments (i.e. the pill or the placebo) and the recovery rates of the patients. The treatment variable is the independent variable whereas the recovery rate variable is the dependent variable. In an experiment, the independent variable is changed.
What is a variable in healthcare?

Is treatment a dependent variable?
Independent Variable (Treatment Variable) Definition and Uses.
How do you identify treatments in an experiment?
Treatments are administered to experimental units by 'level', where level implies amount or magnitude. For example, if the experimental units were given 5mg, 10mg, 15mg of a medication, those amounts would be three levels of the treatment.
What are variables in an experiment?
A variable is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment. Experiments contain different types of variables.
