WEEK 2 (16 -19 SEPTEMBER 2013) Unit 1 Data and Technology

 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

Entry Task: 9/16/2013 What is the mean of the set? How did you find it?

Cube stacking Homework questions…

Worksheet: Mean and median on the number line  Mean and Median on the Number Line student worksheet.docx Mean and Median on the Number Line student worksheet.docx  Home work: Worksheet: Modeling Data 8.1 Topic: Measures of Central Tendency

 Weighted Averages  Test Scores

 I can:  create a box and whiskers plot given a data set  answer questions about a situation using a box and whiskers plot  compare box and whiskers plots and draw statistical conclusions  use the graphing calculator to make a box and whiskers plot Day 3 and 4: Objectives

Questions homework: Measures of Central Tendency….

 Upper Quartile (Q3)  Lower Quartile (Q1)  Median (Q2)  What can you learn from a Box and Whisker Plot? Creating Box and Whisker Plots

 I can:  create a box and whiskers plot given a data set  answer questions about a situation using a box and whiskers plot  compare box and whiskers plots and draw statistical conclusions  use the graphing calculator to make a box and whiskers plot Day 4: Objectives

 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?

 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

:: Comparing graphs of data (worksheet)
