2. Very briefly, explain if the value in the denominator of the one-sample and independent sample t-test is different? If so, what is the difference and why do we use it? 4. How many error scores are in the independent t-test? a. 0 b. 1 c. 2 d. 3 6. Are the 4 steps of hypothesis testing for the independent t-test different from the other statistical tests? 8. What are we hoping that happens to the data of the experimental group? a. the curve takes on a new shape b. the data shifts over on the curve c. the data becomes elevated on the y-axis d. no change to any parameter 14. True or False: You can have a negative number for the Cohen's d or for the percentage of variance explained value? 16.
