I am taking mathematical statistics course in this semester. We learned many things such as covariance , kurtosis , skewness ,p-value,variance,standard deviation etc. We learned how to calculate them , we solved many questions .However , we did not enough pause on the meaning of them. For example, i know how to calculate correlation , but i do not know what correlation gives me , to be more specific , i do not how to interpret the value of correlation and why we need correlation. I think this is very stupid situation but it is not my fault. My professors just give the formulas not meanings.
Because of this reason , i wanted to learn them own myself. I saw that there are some videos about them on youtube , but i am a book person. So , i want you to recommend me some statistics books that gives the definitions detaily, and teach how to interpret the results . As i said , i am like a calculator that calculates the numbers but is not aware of why it is calculated.
