Figure 5
On the left, a histogram titled “Dependent Variable: gentop 6 b” displays “Regression Standardized Residual” on the horizontal axis, ranging from negative 3 to 3 in increments of 1. The vertical axis is labeled “Frequency” and ranges from 0 to 40 in increments of 10. Twenty vertical bars are plotted, forming a roughly bell-shaped distribution. A smooth normal curve is overlaid on the bars. The curve peaks at approximately (0, 27). Summary statistics are printed in the upper-right of the histogram panel, including “Mean equals negative 4,39E minus 16”, “Standard Deviation equals 0,998”, and “N equals 269”. On the right, a plot titled “Normal P–P Plot of Regression Standardized Residual; Dependent Variable: gentop 6 b” shows “Observed Cum Prob” on the horizontal axis, ranging from 0,0 to 1,0 in increments of 0,2. The vertical axis is labeled “Expected Cum Prob” and ranges from 0,0 to 1,0, also in increments of 0,2. Small circular overlapping points lie closely along a diagonal reference line extending from the lower-left to the upper-right. Note: All numerical values are approximated.Scatter diagram results of the data used in regression analysis
