1. Warm Up 1.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 2.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. Class LimitsTallyFrequency

3. Examples Class LimitsTallyFrequency 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

9. Histogram Shape There are five main shape distinctions: 1.Symmetric 2.Skewed left 3.Skewed right 4.Uniform 5.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
