    "How normal distribution is used in data analysis?" - All I needed was this answer. N it took me 1.5 months to get a proper answer. I got bombarded everywhere with theories no one explained how to use it.. Thanks man. I loved your teaching style. This is the problem, we r using this to solve this problem. Now let's talk about what this is.. this should be the way to teach.
