Null hypothesis

Null hypothesis,

Definition of Null hypothesis:

  1. For example, a gambler may be interested in whether a game of chance is fair. If it is fair, then the expected earnings per play is 0 for both players. If the game is not fair, then the expected earnings is positive for one player and negative for the other. To test whether the game is fair, the gambler collects earnings data from many repetitions of the game, calculates the average earnings from these data, then tests the null hypothesis that the expected earnings is not different from zero.

  2. A proposition that undergoes verification to determine if it should be accepted or rejected in favor of an alternative proposition. Often the null hypothesis is expressed as There is no relationship between two quantities.

    For example, in market research, the null hypothesis would be A ten-percent increase in price will not adversely affect the sale of this product. Based on survey results, this hypothesis will be either accepted as correct or rejected as incorrect.

  3. A null hypothesis is a type of hypothesis used in statistics that proposes that there is no difference between certain characteristics of a population (or data-generating process).
