STAT 2126 EL12 2023 W Assignment 2 and Z Scores Variability Task 1: Ordinal Measures of Variability The Five Number Summary includes ordinal measures of central tendency and variability. You already know the values for minimum, median, and maximum. Now use the Quick Quartiles method to estimate Q1 and Q3. It's the same principle as cutting something in quarters by cutting it in half, then cutting the halves in half. Just divide the ordered scores in two halves (5 values in each half). The middle value of the lower half is Q1, and the middle value of the upper half is Q3. Quick Quartiles method can be found in the notes. Use that method only.
