Transforming to Achieve Linearity
Question 2 • DRHS GA-Statistical Reasoning
The lengths and weights for 15 different-sized bluegill fish were measured and recorded. Scatterplot A displays the relationship between the length, in inches, and the weight, in ounces, for each fish. Two transformations of the data are shown in the scatterplots B and C. Scatterplot B displays the relationship between the length and the natural log of the weight. Scatterplot C displays the relationship between the natural log of the length and the natural log of the weight.Which model best represents the relationship between the bluegills’ lengths and weights?
Answer
A
A linear model would best represent the relationship because scatterplot A is fairly linear.B
An exponential model would best represent the relationship because scatterplot B is fairly linear.C
A linear model would best represent the relationship because scatterplot C is fairly linear.D
A power model would best represent the relationship because scatterplot C is fairly linear.
