Then they'll ask you to find the value of a random Y for a given X.
 
If the given X is within the range of the given Xs, it is interpolation. If the given X is outside the given range of Xs it is called extrapolation.
 
There are standard formulae for it. You have to write that down somewhere. For our exam we were given the tables, so we didn't need to even memorise those.
 
Great... Ok..Thats sounds easy... Now I need to see how to find out the Y for that X... when its not linear
I just sat and googled and found out how to solve a least square regression in MS excel... 
Let me see...if there is a short cut for interpolation and extrapolation too in excel LOL
 
More than that ... I need to understand whats univariate and bivariate analysis... I use a software which gives me the output of Univariate,,,, but.. i donno what the output means LOL

Uni variate means that there is only one input...that is X...in multi variate, you'll have an X and a Y and you have to find a Z.

Astonish, domain knowledge is very imp...I was asked to pass the Insurance certification exam which has 4 tough papers and is conducted by LIC, because I was working for a US-based Insurance company. It was added as a must in my appraisal.Stern Smile
 
All the people who were appearing for that exam were senior officers from LIC and New India assurance etc and they were asking me what I was doing there. LOL
 
Then I failed in one paper because I had to go to exam hall straight from office and hadn't got the time to touch the bookPinch I was a laughing stock for several months.
