relevant variables
Researchers organize variables into a variety of categories, the most common of which include:
-

Quantifying solutions:
-
Concentration is a measure of how much solute is dissolved in the solvent (concentration = solute/solution
-
-
-
(increasing solute means more concentrated, increasing more solvent means more dilute)
Environmental Stress:
Environmental stress is anything that may alter the reaction rate between particles on one side of the reaction.

If the [ C2H6] is increased, the concentration of [C2H6] will decrease and the concentration [C2H4][H2] will increase as the equilibrium shifts to the right in order to balance the reactants and products.
-
If C2H6 is removed from the system, the concentration of [C2H6] will increase and the concentration [C2H4][H2] will decrease as the equilibrium shifts to the left in order to balance the reactants and products.

Quantitative data is data expressing a certain quantity, amount or range. Usually, there are measurement units associated with the data, e.g. metres, in the case of the height of a person. It makes sense to set boundary limits to such data, and it is also meaningful to apply arithmetic operations to the data.
