 How would you show a correlation between two types of data?3 Answers***Probably asked based on my prior research experience*** I kinda fudged this one. I said that I'd compute the covariance of the two datasets. My interviewer took the answer but didn't show whether or not he liked that answer.Covariance and correlation coefficient are based on Gaussian assumption, Spearman's rank correlation maybe a better choice if they are totally different types of data. A scatterplot before calculating these statistics is recommended.if two are both quantitative variables, use correlation. if both are categorical, use two way table. if one is quantitative and the other is categorical, then convert the quantitative one to a categorical one then make a two way table.

 What is a normal distribution? What would you think if your data didn't fit one?2 Answers***Probably asked based on my prior research experience*** I was a bit weak on the definition but I had the general idea. A normal distribution is a type of distribution where all the data is centered symmetrically around the mean datapoint, and most other data fit within standard deviations, etc. If my data doesn't fit, either 1) My methods of measuring/processing data are wrong 2) My hypothesis about the nature of my data is wrong.Normal distribution is such that the mean, median, and mode are all equal. If data weren't normal, we may or may not worry that our data is representative of the population. Some things are naturally skewed (e.g. income data). But if, for example, we had height data that was skewed, we might worry.

 What would you rather prefer? SQL or PHP?4 Answershttp://goldmansachs-is-fraud.blogspot.com/It depends on what you're doing with it. SQL is a database and PHP is a programming language. Is this a trick question?Summer intern with no techincal experience the question was just trying to feel what he would be more interested in (PHP- Developer) (SQL - DBA)Show More ResponsesThis question doesn't even make any sense. They should be used in conjunction with each other, not as alternatives to each other. This is a clear test to see if you even have the slightest idea of what you are talking about. If you cannot point out this simple false dichotomy and answer how these are used with each other, then you've clearly never been exposed to the concept of the LAMP stack and probably don't know much about web development.
