I The measurements are given at: http://www.stat.psu.edu/ mga/401/labs/07.s/lab4/ MPA.data.txt I Enter the data in C1 and do a stem-and-leaf display as follows: Graph > Stem and leaf > Select C1, OK Michael Akritas Lecture 22-Lab Chapter 6: Empirical Statistics: Data Graphics Outline Statistical Graphics Estimators Probability Plots Stem-and-Leaf Diagrams Histograms Pie Charts Scatter Plot and 3D Scatter Plot Histograms as Estimators of the PDF I Graph > Histogram > Select Simple > Select C1, OK I Minitab chooses the groups (bins) automatically. For different bins, double-click on the x-axis, choose Binning in the dialogue box that opens, and input the mid-points of the bins, or enter only the desired number of bins. I Histograms as estimators of the PDF: Generate random data from the Gamma(2,1) distribution and see how the resulting histogram approximates the Gamma(2,1) PDF: Calc > Random Data > Gamma > Generate 50 rows of data, Store in column(s)C2, Shape parameter 2, Scale Parameter 1, OK Graph > Histogram, With Fit, OK > Graph variables: C2 , OK Michael Akritas Lecture 22-Lab Chapter 6: Empirical Statistics: Data Graphics Outline Statistical Graphics Estimators Probability Plots Stem-and-Leaf Diagrams Histograms Pie Charts...
