Regression Line of "Apparent Jelly Strength" of Agar Gel on Agar Cncentration (1)

Abstract

The linear relationshi pbetween "apparent jelly strength" (y) of agar gel and agar concentration (x) was investigated for 26 kinds of agar of the various sources. The regression line of y on x was expressed by the followingformula:
y=ax+b
The significances of the coefficient a, the constant b, -b/a, and the estimated error by the regression line were discussed. A practical formula, where the constant b was -50, was also developed for the various possible applications.
