Question

6.3.3 quiz: nonlinear models
by visual inspection, determine the best - fitting regression model for the data
plot below.
a. quadratic
b. no pattern
c. exponential
d. linear

Explanation:

Step1: Analyze the data plot trend

A quadratic model has a parabolic - like shape (either opening up or down). A linear model is a straight - line. An exponential model has a rapid growth or decay. In the given data plot, the points do not form a straight - line (so not linear). There is a pattern (so not "No pattern"). The shape of the data points is not parabolic (so not quadratic). The data points show a rapid growth which is characteristic of an exponential model.

Answer:

C. Exponential
