Unformatted text preview: Continued from Last Lecture How to find the trimmed mean and standard deviation in Minitab Load data into Minitab Suppose C1 store the data sequence with size N=100, we want to find the trimmed mean and Standard deviation with alpha=5%=0.05 Compute n=[N*0.95]-[N*0.05]=95-5=90 MTB>Sort C1 C2 MTB>Copy C2 C3; SUBC>Use 6:95. MTB>Mean C3 MTB>Stdev C3 Chapter 3 Variability in Several Dimensions Section 3.1 Graphical Display and Analysis 1. Scatterplot or Matrix Scatterplot 2. Multiple Boxplots Section 3.1.1 Scatterplots Given N records, each of them contains observed values of K variables, some of these variables might be qualitative(Categorical) and some quantitative. Scatterplots display the values of pairwise quantitative variables in two-dimension plots. Example: PLACE.DAT K=4 in the data set for each record 1 st is categorical, gives the board number The other three are continuous Variable x-dev represents a placement error around the x-axis of the system Variable y-dev represents a placement error around the y-axis of the system Tet-dev is the variable representing an error in orientation Scatterplot of y-dev vs. x-devScatterplot of y-dev vs....
