Subject: Need to user univariate summary stats




I'm currently using query 


sqlContext.sql("SELECT MAX(variablesArray) FROM " + tableName)


to extract mean max min.

is there any better  optimized way ?


In the example i saw df.groupBy("key").agg(skewness("a"), kurtosis("a"))


But i don't have key anywhere in the data.


How to extract the univariate summary stats from df. please help



Thanks and Regards
