# Five Steps in a Hypothesis Test

In all three examples, our aim is to decide between two opposing points of view, Claim 1 and Claim 2. In hypothesis testing, **Claim 1** is called the **null hypothesis** (denoted “**Ho**“), and **Claim 2** plays the role of the **alternative hypothesis** (denoted “**Ha**“). As we saw in the three examples, the null hypothesis suggests nothing special is going on; in other words, there is no change from the status quo, no difference from the traditional state of affairs, no relationship. In contrast, the alternative hypothesis disagrees with this, stating that something is going on, or there is a change from the status quo, or there is a difference from the traditional state of affairs. The alternative hypothesis, Ha, usually represents what we want to check or what we suspect is really going on.

## Hypothesis testing is vital to test patient outcomes.

**What is a hypothesis?**A hypothesis is defined as “a proposition made as a basis for reasoning, without the assumption of its truth, a supposition made as a starting-point for further investigation from known facts”. (The Concise Oxford Dictionary, 1990) **Does your hypothesis have to be true?**You don’t have to be certain that your hypothesis is correct. It is a starting point, a statement that you hope to prove true after more research and investigation. That said, after more research you might find you have to modify your hypothesis. **Why do you need a hypothesis?**A good hypothesis will help you to focus your investigation. It will keep you from “losing the forest for the trees”. As you progress through your investigation you might notice that more and more information comes out. Your hypothesis will ensure that you stay on course in your investigation. **The steps in writing an effective hypothesis**** ****Step One: Preliminary Research**You must review your information so far and decide what information is important and how it will help you develop your hypothesis. **Step Two: Write Your Hypothesis**Your hypothesis is a statement that you intend to prove through your research. It should state your focus. When you have finished with your hypothesis, check it to be sure it has the following criteria: **Transitions in Society, Pg. **

It is a convention that a test using a t-statistic is called a t-test. That is, hypothesis tests using the above would be referred to as "1-sample t test" and "Paired t test" respectively.
