Question 2
A data analyst who works for you is looking at data from 100 individuals on exposure to a potentially harmful substance and the levels of a blood biomarker measured on each individual. In this case higher levels of the biomarker indicate greater harm from the substance. The analyst shows you the following scatterplot of the individual’s biomarker vs. the dosage of the substance experienced by the individual.
Â
The analyst concludes the the relationship between the dosage received of the substance and the response is likely linear. Similarly, your expectation prior to seeing the data was that the relationship would be linear.
What is a conclusion you could make from this plot?
