Activities
- Identify the correlation that would be expected for each of the following data sets as positive, negative, or no correlation:
- The size of the bag of popcorn and the price of the popcorn.
- The increase in temperature and the number of boots sold.
- A person’s shoe size and the number of pets they have.
- Hours spent watching TV and test grades.
- Define positive correlation in regards to scatterplots and give a real life example.
- Sophia and some of her friends rode their motorcycles all day on Saturday. She made a graph that showed the number of gallons of gas remaining at the end of each hour. Describe the correlation.
- Interpret the scatter plot of the data for the amount of memory in a cell phone and the cost.
- Construct a scatterplot for the following fruits and vegetables and describe any patterns you may see: things such as clustering, outliers, correlation and/or linear vs. nonlinear association.
Answer Key/Rubric
- Answers as follows:
