Two-Tailed Test

Two-Tailed: A Two-Tailed Test is a statistical test used in A/B testing where a hypothesis is made about a parameter such as the mean. It tests for the possibility of the relationship in both directions, whether the test statistic is either more extreme than or less than a certain value, but not both. This means it considers the possibility of deviations in two directions, hence, the term 'two-tailed'.
