Difference between one tailed and two tailed hypothesis |
|
Answer» Step-by-step explanation: Our null HYPOTHESIS is that the mean is equal to X. A one-tailed TEST will test either if the mean is significantly greater than x or if the mean is significantly less than x, but not both. ... The one-tailed test PROVIDES more power to detect an effect in one direction by not testing the effect in the other direction. |
