Intro to Mathematical Economics
A one-tailed test is a type of statistical hypothesis test that evaluates whether a parameter is greater than or less than a certain value, focusing on one direction of the tail in the distribution. This test is particularly useful when the research hypothesis predicts a specific direction of the effect, such as an increase or decrease. It contrasts with a two-tailed test, which considers both directions, and is commonly applied in various fields to make inferences based on sample data.
