Be able to fill out a frequency/relative frequency/cumulative relative frequency table Given a set of data, be able to create a box plot, write the min, Q1, Q2 (median), Q3, and max. Be able to calculate the IQR and use it to find outliers. Be able to construct a box plot. Be able to interpret percentiles. Be able to calculate mean, median, mode, sample standard deviation, and variance using your calculator Given a frequency distribution, be able to calculate the mean. Given two scenarios, be able to determine which situation is better using z scores like #22 on worksheet #8. Be able to identify outliers using z scores. This test will be closed book, no notes. You will need a calculator, you won’t be able to use your phone. You need to know what all the various terms in bold mean, but you don't need to memorize definitions.
