1. Suppose you are interested in the use of technology in the classroom. We do an experiment in which we teach each of three sections of a Psychological Statistics class in a different way. One section of six students receives the standard lecture format (blackboard & discussion), a second section of six students receives the same lectures but presented with Microsoft Powerpoint, and for the third section, the lectures are available on the web. The dependent variable is performance on a standardized (final) exam. The data for the three groups follow. Help me to perform an analysis by hand (including a graph of the means) as well as using Excel. If the omnibus F is significant, can you show me how to do that?
