  1. Stem and Leaf Plots By Mr. Chancellor

  2. Stem and Leaf Plots • Stem and Leaf Plots show visually the distribution of data, while also showing the value of numbers

  3. What is a Stem and Leaf Plot? • 4 1 2 3 5 • 5 2 4 6 • 6 1 2 4 • 7 3 4 8

  4. Making a Stem and Leaf Plot Make the list into a Stem and Leaf Plot. 8,6,16,14,12,17,6,6,9,11,11,12,16,7,17,10 (This is the same list from my baseball pitcher!) 0 6 6 6 7 8 9 1 0 1 1 2 2 4 6 6 7 7

  5. Finding the Range using Stem and Leaf Plots 06 6 6 7 8 9 1 0 1 1 2 2 4 6 6 7 7 10 – 6 = 4, therefore the range is 4 Range is the difference between the maximum value and minimum value. (Max value – Min. value)

  6. Box and Whisker PlotsDividing data into Quartiles Quartiles is another way of saying dividing the data into quarters of fourths. • First, find the median (the middle number) • Next, find the middle of the lower number, (not including the median), this is the first quartile Q1 • Lastly, find the middle of the greater value, (not including the median), this is the third quartile Q3

  7. Find Q1 and Q3 for Box and Whisker Plot 6 6 7 8 9 10 11 11 12 12 14 16 16 17 17 66 6 7 8 9 10 11 11 12 12 14 16 16 17 17 Least Q1 Q2 Q3 Greatest First find the median (the middle number) = 11 (which is the Q2)
