Presentation Transcript

  1. Warm Up The data below show the average daily high temperature for Chicago, Illinois, for twelve recent spring and summer months. Construct a stem plot for the data: 64, 61, 57, 68, 78, 75, 50, 83, 71, 58, 62, 80 Display the same data in a grouped frequency distribution table. Use 4 classes. State the minimum, maximum, and class width.

  2. Lesson 6: Histograms We know how to organize the data into different types of frequency distributions. The next step is to take that info and create a histogram with it.

  3. Examples Get out your Worksheet 1.4 #1.

  4. Constructing a Histogram Step 1: Draw and label the x- and y-axes. Step 2: Represent the frequencies on the y-axis Represent the class limits on the x-axis Step 3: Draw vertical bars using the frequencies as the heights

  5. Example #2

  6. Example #3

  7. Example #4

  8. Example #5

  9. Histogram Shape There are five main shape distinctions: Symmetric Skewed left Skewed right Uniform Bimodal

  10. Histogram Shape Go back to Worksheet 1.4 Determine which shape distinction each of the previous work problems. #1 #2 #3 #4 #5

  11. Figure 2.10-pg.54 The distribution of number of engineering doctorates earned by minority students at 115 universities over a 5-year period.
