Using your G*Power Output “4.3.1 GPower Protocol Output”, answer the following questions related to the power analysis you just ran. Create a MSWord document and call it “4.3.2 Short Answer Questions” and save it as a deliverable for this exercise.

1. What type of statistical test did you just estimate power and sample size for?

The test that I used was “Means difference between two independent means (two groups)”.

2. What does a “medium effect size” mean and is this sufficient or this type of statistical test?

0.5 magnitude of difference between the two tested groups and is noticeable, but not a substantial as a large effect and could be sufficient in a test like this, to determined randomness/variety in the subjects tested.

3. What does a power of 0.8 mean, and is it sufficient for this type of statistical test?

The 0.8 means there is an 80% chance of having a p value of less than 0.5 or 5%. Yes, it is significant, because it shows your results are less to occur by chance, but having a .01 or 1% would be a better error probably for a 1 out of 100 result.

4. What does a “two-tailed test mean?

It’s a test where the critical area of distribution, is two sided and tests whether the sample is greater or lesser than .025 or one half of 5% (2.5% on each side of the graph).

4.3.3: Write Up Your G*Power Results: This is what I need help with.!!!

Write up your results in APA 6 format. Be sure to include the parameters of your test and an explanation of what each parameter means (type of test, statistical test, type of power analysis, tails, effect size, alpha level, power, and your calculated sample size). Write up your results and save your write up as “4.3.3 Results Write Up”.
