B. Measures of Central Tendency and Dispersion (variability) by one category. Analyses Using a pivot table, create a table that summarizes the means (averages) for salbeg and salnow by gender. Create a simple bar chart representing these analyses. Using a pivot table, create a table that summarizes the means (averages) for salbeg and salnow by employment category (jobcat). Create a simple bar chart representing these analyses. Calculate the population standard deviation for salbeg and salnow for each gender. Questions 5. What conclusions can you draw from the table of salbeg and salnow means by gender? Specifically, describe the two variables, salbeg and salnow in terms of central tendency and variability. 6. What conclusions can you draw from the table of salbeg and salnow means by jobcat? Specifically, describe the data in terms of central tendency and variability.
