Normality graph
WebA normal probability plot of the residuals is a scatter plot with the theoretical percentiles of the normal distribution on the x-axis and the sample percentiles of the residuals on the y-axis, for example: The diagonal line (which passes through the lower and upper quartiles of the theoretical distribution) provides a visual aid to help assess ... WebNow, drag the formula to cell B7. In cell B2, we have the normal distribution for the chosen data. To make a normal distribution graph, go to the “Insert” tab, and in “Charts,” select a “Scatter” chart with smoothed lines and markers. When we insert the chart, we see that our bell curve or normal distribution graph is created.
