Can be used in demonstration mode for groups of any size. Limited in the lab setting only by the number of computers. Instructor familiar with a computer spreadsheet. A laboratory setting with two students sharing each computer. Sample data from the school or community is very effective.
Students predict population means or proportions, test hypotheses, and examine correlations.
The spreadsheet can be used to compute the mean and standard deviation for a set of sample data. Students use the computer to help make predictions about the population mean and standard deviation, and create confidence intervals. The work with confidence intervals lead to hypothesis testing. The spreadsheet helps students analyze the data for two or more groups, testing for significant differences between means, proportions, and variances. The computer is also used for work with two variable statistics.
