"WebSort the values in the variable from least to greatest. Take the least 50/10 = 5 50 / 10 = 5 sorted values. The greatest value in this batch is the 10% percentile, because 10% of the values in the distribution are less than it. Repeat Step 2 for the next 5 sorted values to compute the 20% percentile, etc. Stop when we’ve computed all 9 deciles. " - Ordered values theoretical quantiles

Webordered values of a variable with quantiles of a speciﬁed theoretical distribution such as the normal. If the data distribution matches the theoretical distribution, the points on the plot form a linear pattern. Thus, you can use a Q-Q plot to determine how well a theoretical distribution models a set of measurements. WebTo construct the Q-Q plots in Google Sheets, use the same methods as explained above to obtain the values to be used to construct the plot. Next, highlight the Normal Theoretical Quantiles and the Sample Data Quantiles columns and click Insert > Chart. On the Chart Editor, in the Setup tab, set the Chart type to Scatter chart.
