Learning statistics doesn’t need to be difficult. This introduction to stats will give you an understanding of how to apply statistical tests to different types of data. You’ll learn about numeric and categorical data and gain an understanding of when to apply a t-test, a chi-square test, ANOVA, and a correlation test. You’ll also learn about hypothesis testing and the p-value. If you’re new to quantitative research or data science, you’ll find this an extremely useful introduction to statistics.

@bangscutter 2 года назад

I think the reason why people find statistics (and math in general) daunting is because usually lecturers and textbooks present the big scary formulas in the first step, and that puts up a mental barrier of understanding with the student. You've explained it very well here without introducing any formulas. Of course, eventually we do need the formulas, but it's far more important to get a grasp of what and why we are doing it first, and then the formulas come in.

@aishwaryar1998 Год назад

Exactly !

@marcoglara2012 Год назад

@@gregmartin Really great breakdown. I have a question. All of these methods test for statistical significance based on a sample or samples selected at random. but I can’t get past the problem here. All sampling is not random. There is always some form of selection bias. Method of data selection, availability of data being sampled, voluntary participation biases, …. These degrade randomness, meaning samples are not selected at random from any population. Wouldn’t that effect the validity of theses significance tests??

No words in this word can describe how much I appreciate the existence of this video. This is among the few of the BEST educational videos I have seen on this platform, or any other platforms....I was taking notes all along, and it serves as an incredibly clear outline for introduction of statistics for someone who has never taken a statistics course but needs it for research. This is the type of video I will 100/100 recommend to others when they need a summery like me. No joke, top 1 on my list, 100% will recommend. I mean, the video itself, the representation, everything is perfect to the point I really, really have no idea how this popped up in my recommendation and only has some nine thousand views!!!! All statistics students, even non statistics student should see this......!! This is the type of content I would wish I can make if I do start making educational videos one day!!! Thank you for being such an inspiration!!!!!!!!

This is (in my opinion) the role model approach to explain a complex problem, simplify it and ultimately understand it.

Thanks much for setting such an elegant example. This is encouraging for myself to pursue and do something similar. Once again thanks for the content, very illustrative.

I'm sure this was an honest mistake due to the wonderful graphical animations this video has. Nevertheless, It is still a very enjoyable, effective video. Thanks Greg!
