MSIT 3000 Test 1 Topics for Review Identify the “Who” of a data set (the cases that are put into the rows of a data table). Distinguish between categorical and quantitative variables. Decide which graphs are appropriate for these types of variables, and be able to interpret the graphs. Calculate proportions from a two-way table, and identify if the variables are independent. Calculate mean, median, Q1, Q3, IQR. Identify skewness, and know whether the mean, median, standard deviation and IQR are appropriate for skewed or symmetric data. Detect outliers using the 1.5IQR Rule. Be able to explain which statistics are appropriate to describe center and spread for both types of variables. Interpret the five-number summary. Interpret boxplots. Use side-by-side boxplots to compare the distributions of one variable divided into two or more groups. Use the 68-95-99.7 Rule to determine values or percentages.
