Question

The contour plot is __________

(a) 1-D

(b) 2-D

(c) 3-D

(d) Any dimension

I got this question during an interview for a job.

This question is from Medium Optimization in chapter Introduction to Fermentation Processes & Media for Industrial Fermentation of Bioprocess Engineering

Answer 1

Right choice is (b) 2-D

The explanation: The axes of the contour plot are the experimental variables and the area within the axes is termed the response surface. To construct a contour plot, the results of a series of experiments employing different combinations of variables are inserted on the surface of the plot at the points delineated by the experimental conditions. Points giving the same results are then joined together to make a contour line. In its simplest form two variables are examined and the plot is two dimensional.
