Question

What are the dixon q test r22 values for n samples between 100-106?

Answer 1

Dixon's Q test r22 values is given by the following formulas:

Consider the sample: x1 < x2 < x3 < x4 < x5 ... x_n-2 < x_n-1 < x_n

-> Suppose x1 is outlier so r22 value is given as:

r22 = (x3 - x1) / x_n-2- x1

-> Suppose x_n is outlier than r22 value is given as:

r22 = (x_n - x_n-2) / x_n- x₃

For n samples between 100 and 106

we get x1 = 100 and xn = 106

r22 = (x3 - 100) / x_n-2- 100 ----------> If x1 is an outlier

r22 = (106- x_n-2) / 106- x₃ ----------> If x_n is an outlier

----------> If x1 is an outlier
