Correlational or experimental designs

Reference no: EM1356147

I have been asked to come up with a research question in psychological statistics.

Can you help me get started by clarifying some of the expectations of the paper.

What is a null or alternative hypothesis?

Should I choose a qualitative or quantitive design? Why would I choose one of the other?

What is the difference between descriptive, correlational or experimental designs? Why?

What would be an example of a varible for this study that could be measured on a nominal scale, ordinal scale, or ratio scale?

Once I've collected all the data would I use inferential or descriptive statistics and why? I need to create a sample frequency distribution for one the variables.
