Inferential statistics 推論統計/Alternate Hypothesis
- Hypothesis
- means a working statement
- things that are expected to be true — some kind of historical or existing expected value.
- means a working statement
- The null hypothesis
- The word “null” can be thought of as “no change”.
- With the null hypothesis, you get what you expect, from a historical point of view.
- The word “null” can be thought of as “no change”.
- The alternate hypothesis
- an alternative to the null.
- For example, if your null is “I’m going to win up to $1000” then your alternate is “I’m going to win more than $1000.”
- an alternative to the null.
Basically, you’re looking at whether there’s enough change (with the alternate hypothesis) to be able to reject the null hypothesis.
The alternate hypothesis is usually what you will be testing in hypothesis testing.
- It’s s statement that you or another researcher thinks is true and one that can ultimately lead you to reject the null hypothesis and replace it with the alternate hypothesis.
