What is a null or alternative hypothesis


Discussion:

Choosing a research question in psychological statistics

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

Questions:

Question.1 What is a null or alternative hypothesis?

Question. 2 Should I choose a qualitative or quantitive design? Why would I choose one of the other?

Question.3 What is the difference between descriptive, correlational or experimental designs? Why?

Question.4 What would be an example of a varible for this study that could be measured on a nominal scale, ordinal scale, or ratio scale?

Question.5 Once I've collected all the data would I use inferential or descriptive statistics and why? I need to create a sample frequencydistribution for one the variables.
