2.2 Graphical Methods for Describing Quantitative Data 1. Consider the stem-and-leaf display below, leaf unit 0.1. Stem Leaf 0 012 2 3 00036 2248 2 1134599 4 457 5 13 How many observations in the data set? How do you decide? a) b) Re-create all numbers, order them in descending order. c) Construct a dot plot.
Use the relative frequency table shown to the right to calculate the number of the 600 measurements falling into each of the measurement classes. Then graph a frequency histogram for these data. Measurement Class Relative Frequency 0.5-2.50 0.15 2.5-4.50 0.15 4.5-6.50 0.10 6.5-8.50 0.05 8.5-10.0 0.20 10.5-12.5 0.10 12.5-14.5 0.10 14.5-16.5 0.15 Graph Calculate the number of measurements that fall into each class. 0.5-2.50 0.15 2.5-4.50 0.15 4.5-6.50 0.10 6.5-8.50 0.05 8.5-10.0 0.20 10.5-12.5 0.10 12.5-14.5 0.10 14.5-16.5 0.15 Graph

Consider the following stem and leaf display for a decimal data set: Stem Leaf 4,5,7 0,0,0,3,6 1,1,3,4,5,9,9 2,2,4,8 0,1,2 4 e) 0 How many observations were in the original data se? Re-create all the numbers a. b.
Consider the stem-and-leaf display to the right. a. How many observations were in the original data set? b. In the bottom row of the stem-and-leaf display, identify the stem, the leaves, and the numbers in the original data set represented by this stem and its leaves. c. Re-create all the numbers in the data set and construct a dot plot. Stem / Leaf 3 / 118 2 / 5777 1 / 3445 0 / 078
