Alternate Hypothesis

Alternate Hypothesis

It suggests that the observations are caused by a specific factor, serving as an alternative to the Null Hypothesis.

Example:

For assessing a student, we would take:

• “The student is worse than average” as the null hypothesis, and
• “The student is better than average” as the alternative hypothesis.

One tailed test

When our hypothesis tests for only one side of the value, it is called a “one-tailed test.”

For example:

For the null hypothesis “the mean is equal to k,” the alternative hypothesis can be:

“The mean is less than k,” or

“The mean is greater than k.”
