Which of the following situations would be an example of correlation not always meaning causation? A. A teacher has three classes that are taught on the same day, in the same building. One classroom has red walls, one has blue walls, and one has yellow walls. She teaches the classes exactly the same. At the end of the semester, the class in the blue room had significantly higher test grades. The color of the room helped the students' grades. B. Over the past 3 years, there has been a increase in lemons imported from Mexico. In the same time frame, car fatalities have decreased. Lemons must be causing the decrease in fatalities. C. An experiment with two groups of plants using different soil. At the end of the study, the plants with soil A were much taller than the plants in soil B. The soil caused the growth.

What real-life situations might show correlation between two things? Is that correlation positive or negative? How might we infer that one event "causes" the other? Is this assumption of causation reasonable? Is there any other explanation? Post at least 1-2 paragraphs that include the following: Describe a correlation in your daily life. Explain how you determined whether one variable caused the other using scientific and statistical methods (including a scatter plot and correlation coefficient). What factors need to be considered to establish a causal relationship? Decide whether your scenario is a positive or negative correlation. Make sure to explain.

In each situation, tell whether a correlation is likely. If it is, tell whether the correlation reflects a causal relationship. Explain your reasoning. the price of hamburger at a grocery store and the amount of hamburger sold
