3. You conduct an experiment in which half the people get a special get-out-the-vote message and others do not. Then you follow up after the election with a random sample of 500 people to see if they voted. (a) What will be the standard error of your estimate of effect size? Figure this out making reasonable assumptions about voter turnout and the true effect size. (b) Check how sensitive your standard error calculation is to your assumptions. (c) For a range of plausible effect sizes, consider conclusions from this study, in light of the statistical significance filter. As a researcher, how can you avoid this prob- lem?
