Normal probability plot of data
WebIn a normal quantile plot, the data points are plotted against the expected values of a normal distribution. If the data points fall along a straight line, it suggests that the data is normally distributed. In this case, the normal quantile plot shows a straight line that rises from left to right, passing through (150, -1.3) and (250, 1.5 ... WebStep 2: Visualize the fit of the normal distribution. To visualize the fit of the normal distribution, examine the probability plot and assess how closely the data points follow …
