PSYEIIS I Amanda [.Egun,Ph.D. I Marian University Indianapolis PSYZOS: CH. 2 WORKSHEET Creating, Graphing, 8L Interpreting Frequencv Distributions Show your work for full credit. 1. If you were graphing total acres of farmland in each of the states in the United States Midwest, which of the following graphs would be most appropriate? a. Histogram b. Line Graph c. Frequency Polygon d. Bar Graph 2. You may have heard or read that the normal body temperature {oral} for humans is 98.6F. The numbers below are temperature readings from healthy adults, aged 18 to 40. Arrange the data into a grouped frequency distribution, using 99.3 99.5 as the highest class interval and 96.3 965 as the lowest. {Data is based on lVackowiak, Wasserman, 84 Levine, 1992]. 98.1 97.5 97.8 96.4 96.9 98.9 99.5 98.6 98.2 98.3 97.9 98.0 97.2 99.1 98.4 98.5 97.4 98.0 97.9 98.3 98.8 99.5 98.7 97.9 97.7 99.2 98.0 98.2 98.3 97.0 99.4 98.9 97.9 97.4 97.8 98.6 98.7 97.9 98.4 98.8 PSYEIJS I Amanda [.Egun,Ph.D. I Mnriun Universirylndiunupolis 3. Describe how a line graph is different from a frequency polygon. 4. Many variables {e.g.. height of fully grown adults] tend to be normally distributed, but many other variables are skewed. Describe a variable that you think is likely skewed, either positively or negatively. Provide a brief rationale for why you suspect that distribution is likely skewed and in which direction. Sketch what you think the distribution may look like
