Transforming to Achieve Linearity — Unit test

Question 6 • DRHS GA-Statistical Reasoning

Bacteria growth was measured over a one-month period. Scatterplot A displays the number of cells measured over the recorded number of days. Two transformations of the data are shown in the next two graphs. Scatterplot B displays the relationship between the number of days and the natural log of the number of cells of bacteria. Scatterplot C displays the relationship between the natural log of the number of days and the natural log of the number of cells of bacteria. Which model best represents the relationship between the number of days and the number of cells of bacteria?

Question illustration
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 B is fairly linear.
D
A power model would best represent the relationship because scatterplot C is fairly linear.
