WebFeb 26, 2024 · When you have more than n= 10 pairs, Kendall’s Tau generally follows a normal distribution. You can use the following formula to calculate a z-score for Kendall’s Tau: z = 3τ*√ n(n-1) / √ 2(2n+5) where: τ = value you calculated for Kendall’s Tau. n = number of pairs. Here’s how to calculate z for the previous example: WebAnd x n-2 means the term before that one. Let's try that Rule for the 6th term: x 6 = x 6-1 + x 6-2. x 6 = x 5 + x 4. So term 6 equals term 5 plus term 4. We already know term 5 is 21 and term 4 is 13, so: ... When in doubt choose the simplest rule that makes sense, but also mention that there are other solutions.
