The building structure in this case is represented by three variables namely Structure = 0; Structure = 1; and Structure = 2.
Pain intensity was evaluated by applying two variables, namely a 0 100 visual analogue scale (VAS) to assess the intensity of pain (0 = no pain, 100 = extreme pain) and a rating item from the SF-36 (pain in last week, six response categories).
In the reduced model, the T-cell population system is represented by just two variables, namely E and R, representing the size of activated T cell populations and the stochastic effects were eliminated substituting R E, R R respectively by their expected values Λ E, Λ R (see eq. 5-6 in methods).
The tests were carried out on solutions of cheese sweet whey powder by a factorial experiment design of two variables, namely treatment temperature and time, at three levels, 75, 80 and 85 °C, and 300, 750 and 1200 s, respectively, with three central points.
The best model to predict 24-h urinary creatinine excretion consisted of only two variables, namely body cell mass determined by BIA and gender.
Two variables namely feed rate and knife speeds were studied.
It is using quantitative research i.e. correlational analysis between two variables namely appreciation of historical building and visitor behaviour.
For the optimisation of these two variables, namely the suspending agent's content, a Doehlert design was applied.
For quantification, we scored for two variables, namely intensity of staining and number of positive cells.
