Today I was thinking we would come in, talk about the test we took Tuesday, and leave. Instead we went over correlations and scatterplots and the different ways variables can be related. It was fun to have open discussion about some different relationships we see in life. One that particularly stood out to me was as the number of tests in a day increases, the grades on those tests decreases and the stress level increases. Oh, so true. We also talked about being careful when making assumptions about data that appear to be related. Just because a relationship appears to exist does not mean that it actually does. We said that the actual cause of the relationship may be another factor entirely. This was probably what happened in the case of the larger-foot children having larger vocabularies. Age might have actually been the factor in this.
