course delivery format in a psychological statistics class

Suppose you were going to create your own study to examine what course-delivery format (online, blended, or face-to-face) leads to the best performance in a psychological statistics class. In a paper identify the following for your study:

What is your research question? What is your hypothesis (both null and alternate)? Is this a qualitative or quantitative design (based on type of variable collected) and why? Is this a descriptive, correlational or experimental design and why? What would be an example of a variable for this study that could be measured on a nominal scale? Ordinal scale? Interval scale? Ratio scale? Once you have collected your data, would you use inferential or descriptive statistics and why? Create a sample frequency distribution for one of the variables. Choose either a simple or grouped frequency distribution and explain your choice.
