Open excel file > minimize > open phstat (extra features) > enable macros > add-ins. For contingency table: add-ins > phstat > descriptive statistics > two-way tables and charts > side by side (if you need one) All values divided by the total number of items being added up: formula for population mean n i x i . = x with the bar over it means average of sample. U = (cid:894)greek letter (cid:862)(cid:373)u(cid:863)(cid:895) a(cid:448)erage of populatio(cid:374) N = observation of population: weighted mean. Quiz 1 18/20 worth 5%: so you would times 18 by 0. 05. Multiply each x value with the assigned weight > add them up > then divide them by total of the weights (same as before: median. Arrange from the lowest to the highest. The median is not sensitive to outliers (unlike the mean and mode)
