How Are Moments Used in Statistics?

In this video I explain how moments are used in statistics in order to describe the characteristics of a distribution. The first four moments help to tell us about the mean, variance, skew, and kurtosis of a distribution and allow us to make comparison between distributions. I define raw or crude moments and how changing reference points can provide centralized and standardized moments to describe the shape of a distribution.

I want to study psychology but I don't know how to start I don't know anything about psychology

I'd recommend starting with a general overview so you can become aware of the different areas of psychology and some of the general principles for thinking about psychological topics. It's important to have a sense of the main approaches (biological, behavioral, cognitive, sociocultural) before choosing a specific area so that you know how different perspectives would approach it; what types of questions each would consider and how these might fit together. I have a playlist of all of my intro psych videos in order on my channel, or you could choose from the playlists by unit. These are also organized as a free open course here: psychexamreview.com/open-course/ Hope this helps, feel free to ask in the comments if you have specific questions on any videos!

@@PsychExamReview thank you very much I will go to the playlist
I don't know what I should study first but I think I love to know how people think and how can I control my mind and why people do some things they don't like it and where our ideas came from and How can I manipulate people? Not to do bad things to people just to have knowledge

Why we think ? I think that question is nothing

@@AHMEDTANJAWI-ms5qv What you'll discover is that this is actually an infinitely complex question (though that shouldn't be discouraging!).
Trying to fully understand why someone has a particular thought or engages in a certain behavior means that we would need to consider their biology (genes, hormones, neurotransmitters, brain function) both at that moment and potentially extending over millions of years of the evolutionary past, their previous experience with the world (rewards, punishments, & other environmental factors, which also influence gene expression) leading up to that moment, their patterns of thinking, language use, and stored knowledge and perceptions of the world (called schema) as well as potential distortions & biases that may influence which of these they are drawing from, as well as their culture, past social experiences and relationships, and their unique interpretation of this particular social interaction.
Identifying a definitive answer that incorporates all of these is essentially impossible, but that doesn't mean that we can't draw any conclusions or consider the most important factors for some types of thoughts or behaviors.
So psychologists using different approaches may focus on the importance of different aspects for certain situations, but this doesn't mean that one explanation will always be correct or will be the "best" explanation for other thoughts or behaviors or for other individuals (though some psychologists occasionally seem to forget to keep this in mind).
Hopefully this glimpse of the complexity of human thought and behavior inspires you to want to learn more; don't accept simple answers and remember there are almost always more possibilities to consider.
