Normal Distribution Video Tutorial for Beginners

Normal distribution is very impotant. So, we should learn its basics. I have made its first video for discussing all about it .

About Normal Distribution
  1. It is distribution of continuous series.
  2. This distribution shows the distribution like 0 to 5, 5-10 and more up to infinite.
  3. This distribution can be shown as normal distribution curve form for calculating the value of its area that will be between + infinite and - infinite
  4. For calculating the area we have to calculate value of z first
  5. Z = X - mean / standard deviation
  6. Now we calculate the area of Z from table and  this will be the probability and its exact value can be calculated by making graph of normal curves.
