Exercise 5.1 Correlation Analysis Figure 6 shows measurements from a process together with a mathematical approxima- tion of the process. a) Determine the coordinates of all data points in figure 6 and list them in a table. b) Calculate the correlation coefficient for all data points of figure 6. c) Now calculate two correlation coefficients for figure 6. For the first one use all data points, where the x values are smaller or equal to zero. For the second one use all data points, where the r values are bigger or equal to zero. 1 y 0.5 -1 -0.5 0 0.5 1 Figure 6: Measured data points from a process.
