Height vs. Shoe Size and Hair Lenth Scatter Plots - Due Fri. Oct. 3rd

Blog Post Assignment #2 - Reading Scatter Plots and Understanding Correlations.

On your own academic blog please respond to the questions below each of the following graphs. You don't need to copy the questions, but you should write in complete sentences so your reader knows what you are talking about. In your post you should either copy the graph images from my blog or link to them in your post using the link button (it looks like a little chain link just to the right of the Text color button at the top of your "new post" window.) Be sure to e-mail me to let me know your blog post is up. Put your full name and "AP Psych" in the subject line and in the body of your e-mail.

Above is the data we collected about our shoe sizes vs our heights. Can you see a relationship? Is there a correlation? If so, is it positive or negative? Does shoe size cause height to change? Does height cause shoe size to change? Does correlation imply causality?

What can we see from this scatter plot of hair length vs. height? Is there a correlation? If so, is it positive or negative; strong or weak? What information about the students in our class does this graph give you?

Do we have to answer the questions below each graph?

Hello Saul,

I know you love math, so I bet you can't wait to answer. I was planning to give the assignment on Monday after we work with the data a bit in class, but if you want to get a head start, please go ahead. The assignment will be to answer the questions on your AP psych blog. and then e-mail me to let me know you've updated it.
