Thank you for your video. I'm doing an online MIT course, and it totally mis-judges the learner's stat's knowledge. Your videos are a live saver :)

Hello, thank you very much for your videos! I am a bit lost as I am doing my thesis and I am really struggling to understand what type of data analysis I need to use. My research is about the public's motivations to attend mega-events (Likert scale questionnaire), I am not comparing anything, just looking at what kinds of aspects ( for example spacious seating) events should have to attract the people. I did the descriptive analysis at first, but it would only show the preferences of my sample. While I would like my gathered information to be used for organising future events. Could you please help me out? Thank you

Sorry Paula, I don't have enough information to be able to answer this. I suggest you ask your supervisor for help.

If data consist of 900 rows i want to apply multiple regression do I have to take sample only ? Can I apply on it all? Is valid?

900 rows is great. Is the data a sample of something else or the total population? If it is the total population you don't need to do inference. Can you tell me what it's about? How many variables?
