 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.

 Find all duplicate strings in a list of strings and return a list without duplicates Which is more efficient to find a character in a list of 1000 characters, using a LinkedList or Array?2 AnswersUsing a hashset (to remove duplicates)Convert the original list to a set implemented by hashing (This should be given as the HashSet class in Java, or the set structure in Python) Convert this hashset back to a list. (should contain all of the elements minus the duplicates) Find the symmetric difference between the original list and the new list (should contain the duplicates) I do believe it is more efficient to find a character in an Array than in a linked list because an array is a contiguous portion of memory that the computer can easily perform pointer arithmetic on and iterate through. The same guarantee of contiguous memory does not exist for LinkedList because nodes are linked by memory references to each other. The necessity of node references, which themselves rely on a Node or some other data structure, does guarantee that a LinkedList will also consume much more memory than an array due to overhead.
