Effect size. Significance tests inform us about the likelihood of a meaningful difference between groups, but they don't always tell us the magnitude of that difference. Because any difference will become "significant" with an arbitrarily large sample, it's important to quantify the effect size that you observe.
STATISTICS: Hypothesis Testing
Objectives 1) Able to formulate statistical hypothesis 2) Discuss the two types of errors in hypothesis testing 3) Establish a decision rule for accepting or rejecting a statistical hypothesis at a specified level of significance 4) Distinguish between the one-sample case and two-sample case tests of hypothesis concerning means 5) Choose the ...
PDF Lecture 7: Hypothesis Testing and ANOVA
The intent of hypothesis testing is formally examine two opposing conjectures (hypotheses), H0 and HA. These two hypotheses are mutually exclusive and exhaustive so that one is true to the exclusion of the other. We accumulate evidence - collect and analyze sample information - for the purpose of determining which of the two hypotheses is true ...

23.1 How Hypothesis Tests Are Reported in the News 1. Determine the null hypothesis and the alternative hypothesis. 2. Collect and summarize the data into a test statistic. 3. Use the test statistic to determine the p-value. 4. The result is statistically significant if the p-value is less than or equal to the level of significance.

The alternative hypothesis (denoted H1 or Ha) is a statement that the value of a population parameter somehow differs from the null hypothesis. The symbolic form must be a >, < or ≠ statement. We will be testing the null hypothesis directly (by assuming it's true) to reach a conclusion to either reject H0 or fail to reject H0.

It's Two One-Sided Tests. When reporting tests of significance, researchers might claim to have conducted a twosided test when in fact they have conducted two one-sided tests. Mark Rubin explains the confusion and how to avoid it. 8-1 We must deal with uncertainty in our decisions because we rarely know the values for population characteristics.

8. Rules for testing hypotheses 1. Your expected conclusion, or what you hope to conclude as a result of the experiment should be placed in the alternative hypothesis. 2. The null hypothesis should contain an expression of equality, either =, or . 3. The null hypothesis is the hypothesis that will be tested. 8. 9.
