:''' | :'''Q6:''' First, walk us through the result visualized in Figure 1. Explain and interpret the result for us. Now go back to the blockquote on page 329 and, by referencing the figure, explain why Gelman and Stern think that this is a good example to illustrate their point about the difference between statistically significant versus non-significant. | ||
:''' | :'''Q7:''' Move on to the study about EMF. Walk us through Figure 2. First explain the basic result and then explain why Gelman and Stern thinks that Figure 2b is better than 2a. | ||
:''' | :'''Q8:''' In the paper's abstract Gelman and Stern describe their approach as different from three other problems: that statistical significance, that dichotomization of significant/not-significant encourages dismissing observed differences, and that thresholds are arbitrary. Summarize why these are important issues in your own words (and ideally, with examples) and explain how Gelman's key critique is different. |
