I created a new function called median.…And that function, just like my mean function,…the median function is going to take in…a multidimensional slice.…So, once again, this is all of my records.…And here is one record.…Each record is a slice a fields.…And then it also takes in the index position…of the data I want to access in that slice of fields.…So, the first thing I do is I create a slice of Float64.…
