Answer #1

Correlation is used to find the linear relationship between two numerically expressed variables.

Eg----------------

,No of policyholders and the event of happening of a claim.,As the number of policyholders increase,the chances of concerned event occurring also increases. This is used by insurance companies.....

Description--

Whenwe look at scatterplot, we should be able to describe the association we see between the variables.

A quick description of the association in a scatterplot should always include a description of the form direction ,strength of the association, along with the presence of any outliers.......

Note-if there is any understanding problem regarding this please feel free to ask via comment box..thank you

You see scatter plots of three pairs: Y versus X1, Y versus X2, and Y versus X3. If each of the first two scatters is fairly close to a straight line, but the third is more a shapeless swarm of points, which of the following can you conclude? a. It is possible that a regression with all three X's could have an appreciably higher R-square value than a regression with only X1 and X2, due to the correlation structure among...
