Locate a randomized study (on your group's research topic if possible) and examine the results. Find a study that included construction of confidence interval(s) for population parameter(s) of interest and discuss these. Talk about such things as margin of error and the standard error of the estimate. Explain why the researchers felt that predicting this(these) population measure(s) was important. How was construction of this(these) confidence interval(s) important in answering the research question(s) for the researchers? If the confidence interval was for a difference of population parameters, explain why the difference was/was not statistically significant and what this means. Briefly explain the research methods used to obtain the data to construct the confidence interval(s): study type, sample sizes, protocols, etc.
