1. Bell Ringer 1) In class we are going to explore 7 different data displays. How many ways can we learn all 7? 2) List all 7 displays you think we will discuss: Stem-and-Leaf Plot, Box-and-Whisker Plot, Scatter Plot, Line Graph, Circle Graph, Bar Graph, Histogram Permutation: 7! =5,040 ways

2. Today’s Agenda 1) Bell Ringer/HW 2) Presidential Elections 3) Analyzing Stem & Leaf Plots and Box & Whisker Plots 4) Team Huddle 5) Homework

8. Collecting Data Essential Question: How do you construct and analyze a box-and-whisker plot?

9. Box-and-Whisker Plots Shows how data are distributed by using a five-number summary: 1. minimum value 2. lower quartile (Q1) 3. median (Q2) 4. upper quartile (Q3) 5. maximum value

11. Think About It George Washington was 57 when he was elected into office. Abraham Lincoln was 51. If these two ages were added to the data, what things would change? What things would not change?
