(f) Government standards call for cars to get 28.5 MPG. Do you think that these are coding errors? (e) Identify any unusual values (outliers). Since the coefficient of variation indicates that the standard deviation is about of the mean, the variation is relatively for this sample. (d) Find the coefficient of variation and briefly interpret its value.Īnswer: The coefficient of variation cv is 0.19. The mean is the balance point of the histogram. Notice that JMP has automatically displayed a modified boxplot of Hwy mileage in each of the preceding Distribution reports and placed it to the. The mean is the balance point of the histogram. Color Black White Red Green Blue Yellow Magenta Cyan Transparency Transparent Semi-Transparent Opaque. How are these related to the histogram, if at all? To create clustered boxplots for two qualitative variables, first create a new qualitative variable consisting of all category combinations (using computer help. Color Black White Red Green Blue Yellow Magenta Cyan Transparency Opaque Semi-Transparent Transparent. (c) Find the mean and standard deviation of the rated mileages. The location of the middle half of the values What does the boxplot tell you that the histogram does not? Select all that apply.Īnswer: A.The presence or absence of any outliersĭ. What does the histogram tell you that the boxplot does not? Select all that apply. What does the histogram tell you that the boxplot does not, and vice versa? Which boxplot below represents the data? (b) Compare the histogram to the boxplot. It appears as default output when you choose the Effect Screening emphasis. In version 13 of JMP this functionality is brought to the foreground. Most models all have about the same MPG with some slightly higher and some slightly lower. Box-Cox transformations have always been a feature that has been tucked away under the red triangle options of Fit Model. Which statement below best interprets the histogram?Īnswer: C. X( :Species ), Means and Std Dev( 1 ), Box Plots( 1 ), Mean Error Bars( 0 ). Which statement below best describes the histogram? 1: Open a data set provided by JMP 2: Create several individual graphs. Since box plots are usually vertical (so values go up-down). Make histogram in JMP and change x-axis scale There is the option to save an analysis as a JMP script.
