Student's t-test

Line breaks: Stu|dent's t-test

Definition of Student's t-test in English:

noun

A test for statistical significance that uses tables of a statistical distribution called Student’s t-distribution, which is that of a fraction (t) whose numerator is drawn from a normal distribution with a mean of zero, and whose denominator is the root mean square of k terms drawn from the same normal distribution (where k is the number of degrees of freedom).
Example sentences
  • Using an unpaired Student's t-test, statistical significance was assigned to comparisons with P values 0.05.
  • Because we do not know that the values have normal distribution, the Wilcoxon test is preferred over the Student's t-test.
  • Statistical significance for data was determined using the Student's t-test, with p = 0.05 denoting significance.

Origin
