Your response variable is binary, activity or no activity. You set up and experiment with three different plants and three different kinds of UV lights, no UV, moderate UV, and high UV. A researcher measures the value of the response variable without attempting to influence the value of either the response or explanatory variables. The changes in an experiment are made to the independent variable (also called the manipulated variable); the responses that happen as a result of those deliberate changes are the responding variables. An explanatory variable is one that explains changes in that variable. The variable you change would be the amount of light. A response variable is classified as a dependent variable. Define treatment.

The interquartile range is the difference between 1st and 3rd quartiles. Variables can be classified as categorical or quantitative.Categorical variables are those that provide groupings that may have no logical order, or a logical order with inconsistent differences between groups (e.g., the difference between 1st place and 2 second place in a race is not equivalent to the difference between 3rd place and 4th place). The proxy variable can be a characteristic that is not of any great importance itself, but has a good correlation with the confounding variable. Thus a response variable corresponds to a dependent variable while an explanatory variable corresponds to an independent variable.
