Okay We will now look into the inferential statistics and regression analysis these are statistics we will be using our programming language. So, inferential statistics and these are as I say, regression analysis or linear regression analysis will be in this data understanding stage. So, let's say to find a correlation correlation is a Statistical Association to find how close to variable is and the raw data linear relationships between them. So, we can generate the data. So, let's say I can generate a data something IDs So, I can generate a data key So I need to remove all those Okay, we can generate the data Okay, so I have a data set here okay the data to be changed really Okay, so variable one variable two the number three okay. So this is one way to generate data so Han Omar says a random number ization function and there are 100 rows and then meanies to a standard deviation is one okay so we we can find correlation using these correlation functions.

So co one, variable one variable two co our data variable one data. Okay. C oA data variable one, data variable two. Okay so I don't get a correlation here. So is minus 0.04953215 so this is how we can get correlation
