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.
