I can: represent the mean of a set of numbers using cubes/stacks explain the mathematical difference between mean, median, and mode using stacks of cubes or a histogram. predict what will happen to the mean or median when adding data to a data set explain the mathematical difference between mean and median and represent both using a line plot create data sets that have specific characteristics use the graphing calculator to compute mean and median for a data set. Day 1 and 2: Objectives

13
Brad and Tom are comparing their classes' scores on a math test. Both of their classes had mean scores of 80 on the test, but Brad's class had a range of 6 while Tom's class had a range of 30. If the highest possible score was 100, which class had the LOWEST score in it? Which Statement would be true? Brad's class had the lowest score in it. Tom's class had the lowest score in it. The lowest score occurred in both classes. It cannot be determined from the information. How do you know you are right?

14
Median (Q2)- The “middle” of the data Upper Quartile (Q3)- The “middle” of the upper half of the data Lower Quartile (Q1)-The “middle” of the lower half of the data What can you learn from a Box and Whisker Plot? Creating Box and Whisker Plots
