Correlation

Grade 9s measured the televisions in their homes last night. We compiled the data today to see if TVs length and width are related.

We looked at lines of best fit for linear graphs, and curves of best fit for non linear graphs. We talked about direct and partial, negative and positive, and strong and weak correlation.

We looked also at what interpolation and extrapolation are, and how to use the line of best fit to estimate values.
