6 Scope of the study 1. A variation of the definition of the Kendall correlation coefficient is necessary in order to deal with data samples with tied ranks. You assume nothing is going on ( null hypothesis) you take a sample. Formally, the Kendall’ s tau- b is defined as follows.
The more inferences are made, the more likely erroneous inferences are to occur. You’ ll compute the probability of getting your sample ( assuming that the null hypothesis H 0 is true one of two things will happen. Writing null alternative hypothesis.
