In your discussion this week, you'll dive into the concept of correlation, causation, and lurking variables. To

demonstrate this, I performed this fascinating study over the summer where I learned that taller people are better

at math than short people. I know you may not believe me, but it's true. Let me prove it to you.

By the end of this video, I will have you convinced that our results are accurate. What are the various aspects of

math that people need to understand? For an example, counting, addition, subtraction, fractions, decimals, and

finally, geometry and algebra. We can all agree that this is the progression of mathematical ability for the average

student.

On our y-axis, we'll plot heights. How much mathematical ability does a person have when they are 1 foot tall?

None, they're a baby. When a person's 2 feet tall, they can probably count to 10. A person who's 3 feet tall should

be able to add and subtract. At 4 feet tall, they should be able to perform fractions and decimals. At 5 feet tall,

they should be able to complete algebra and geometry problems.

Looking at our chart, the data clearly shows that people who are taller are better at math. But what's the problem

with my study? Age. Age was never mentioned in my study. By leaving out age, I'm leaving out a confounding or

lurking variable.

While this is a simple example, this happens often in real life studies. This is why we need to check the reliability of

our studies and consider any lurking variables that may not have been considered when conducting the study.

In this week's discussion, you will design a similar study that has a false correlation caused by other variables.

Your classmates will need to try to correctly identify the lurking variable in your study.

Prior to beginning work on this discussion forum, read Chapters 3 and 4 of your textbook.

Design a study that has a false correlation caused by lurking variable. Watch this week's video for an example study, and to learn more information about this concept.

Guided Response:Your initial response should be a minimum of 300 words in length. Respond to at least two of your classmates by commenting on their posts. In your response, identify the lurking variable in your classmate's study, and explain how the lurking variable may cause a false correlation.
