As a data scientist, you will use many different methodologies to analyze the data sets you are working with at Microsoft. Often these methodologies involve several steps, assumptions, or other items. A common practice during an interview is providing the Microsoft interviewer with a list of items in your answer. Organize your answer and make sure that none of the items are repeated in your answer.

"There are several assumptions that I use when performing a linear regression analysis. Some of these include:
oEnsuring that the data I use in the sample is representative of the population
oDetermining if the variance of the residual is the same for any value of X
oConfirming that the relationship between X and the mean of Y is linear
oReviewing the observations to ensure that they are unique and independent of each other"
