Why it is said all statistics are data but all data are not statistics?
All statistics are data because all statistics are formed of numbers and numbers are a type of data (numrical). But not all data is statistics because not all data is numbers, it can also be words, pictures etc. It's like saying all apples are fruit but all fruit are not apples.
If you missed 4 on a test with 26 questions what is your finnal grade?
That depends on your teacher's or schools practice. If they "grade on a curve" then all the tests taken will be distributed on a Gaussian bell probability curve. So if you are the only one who missed 4 questions and everybody else missed more you will get the highest grade; but of you are the only one who missed 4 questions and everybody else mised fewer, then you will get the lowest grade. In my school only a few teachers graded on a curve; most would have given a B for missing 4 out of 26 equally important questions. UH UH!If you missed 4 out of 26, you would still get a A-.I aked my teacher and she said yes.

Why do you have statistics?
Notice that the word statistics is closely related to the word state. Some statistical methods were initially developed by governments as ways of gaining greater control over their populations although it must be said that at the same general time in history individuals such as Florence Nightingale were using statistical methods to try to influence governments to take better care of their citizens.Nowadays we use statistics whenever we can reasonably assume that random phenomena are at play that we need to take in to account.
