Null Hypothesis

April 1st Fact-of-the-Day

In hypothesis testing, a null hypothesis is the hypothesis that is being tested. For example, if you wanted to test whether rotation of your 20-meter beam changes the radiation pattern of your 10-meter J-Pole, you would want to test the null hypothesis 'Rotation of my 20-meter beam has no effect on the radiation pattern of my 10-meter J-Pole.' If you then measured the radiation pattern of your 10-meter J-Pole while rotating your 20-meter beam into various positions and found that your 10-meter J-Pole radiation pattern changed, you would reject your null hypothesis. ©2005 Martek International All rights reserved.
