The research that links graph interpretation with statistical reasoning, in particular, summary measures, appears to be based primarily on K-12 students, though misconceptions or superficial understanding of measures of center have been cited at all levels of education. Today you’ll learn how to create impressive scatter plots with R and the ggplot2 package. How to Identify Common Probability Misconceptions. While working with third-graders at Hellgate Elementary, I was faced with one such mathematical misconception. It’s a tough place to be. The biggest issue I have seen is mixing up no solution and a solution of zero. Figure 4.1 An example of a line graph 0 10 20 30 40 50 60 70 80 0 102030405060 Temperature (°C) Time (min) Beaker (100cm3) containing hot water (50cm3) left to cool The following is a summary of the points that need to be considered during the construction of a line graph. The content being taught was graphing ordered pairs on a coordinate plane. 2 ‘Graph-as-picture’ misconceptions in young students. The graph, if it is fit for use, will provide information suitable to its intended audience and purpose. Yes, it might be biased, but decisions are always constructed, so they are always biased by their builders and their designers. Luckily, R makes it easy to produce great-looking visuals.
