State what kind of distribution is appropriate for the data
Normal t Binomial Geometric
Chi- Square Poisson or other
AND state if you are you comparing
A population to a sample (called a 1 sample _____ distribution)
(fill in blank with the word “normal” or “z” or “binomial” ect)
OR are you comparing two samples to each other (called a 2 sample_____
distribution)
Choose type of test:
1 tailed test (< or >) or a 2 tailed test (not equal)
A sketch is good idea
Use correct format of H0 and Ha
H0 : ____= ____
Ha: _____ >, <, or not equal ____
Or state null and alternative hypothesis using sentences.
In general, use Greek symbols in hypothesis, not regular
alphabetic symbols
****If you are going to set an alpha, do it HERE ****
Correct calculation of standard deviation
This is determined by knowing which distribution you chose.
Correctly calculate test statistic (the z score, or t, or chi--square)
Correct P-value (doubled for two tailed)
Correct decision In general, a small P-value indicates you should reject H0. A large P-value indicates you should fail to reject.
Correct and complete statement of conclusion, restating the question.
Example of a perfect conclusion: “I reject the null hypothesis.
Since the possibility of having a sample mean of 20.1 is so small when
the population mean is 18.2, (P-value of .0002) I conclude that Logan High’s
mean ACT is truly different from the national mean ACT."
OR: "I fail to reject the null hypothesis. There is not
enough evidence to show that the sample mean of 18.1 is different from
the population mean of 18.2. My P-value of .31 indicates I
could have gotten results this close to the population mean in random samples
31% of the time. "
Always use excellent organization, clarity and readability.
