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

Today’s Agenda

1) Bell Ringer/HW 2) Presidential Elections 3) Analyzing Stem & Leaf Plots and

Box & Whisker Plots 4) Team Huddle 5) Homework

Essential Question:How do you construct and analyze

a box-and-whisker plot?

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

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?
