The coefficient of determination of 22.9% indicates that 22.9% of the total variability in the Y-values (the sweetness) can be explained through the predictor variable which is the Pectin Level. The value is not high, so as a predictor of Sweetness, the Pectin Level may not be very good.

Exploring Data on the TI-83
Correlation Coefficient - r . r is the strength of the linear regression. –1 < r < 1. ( is a perfect correlation between x and y. Zero is no linear correlation. The sign refers to ( slope. r2 is the measure of the fraction of total variation in the values of y or how closely the data points are clustered in a small band.
