Treatment: In an experiment, the manner in which
researchers handle subjects is called a treatment. Researchers are
specifically interested in how different treatments might yield
differing results.


Observational Study: An observational study is when an experimenter watches a group of subjects and does not introduce a treatment.


Example: A Survey or collection of data.


Independent Variable: The independent variable of a
study is the variable that experimenters choose to manipulate; it is
usually plotted along the x-axis of a graph.
