I’m experimenting with data from the Wolfram data repository. I picked US Fatal Injuries 1999-2014 as an example. I looked at the example on the website: https://datarepository.wolframcloud.com/resources/dzviovich%3AUS-Fatal-Injuries-1999-2014

Rather that just imitate it, I wanted to pull some data from it. The data is all in Time Series. I tried to follow the documentation in Mathematica to extract something, anything really, from the time series. I ran the following code:

y = ResourceData["US Fatal Injuries 1999-2014"]; z = y[Select[#Sex == "Male" && #AgeGroup == "< 15" && #Race ==    "All races" && #InjuryMechanism ==    "All Mechanisms" && #InjuryIntent == "Homicide" &], "Deaths"] 

The output was:

The documentation on TimeSeries has the following example.

The average value of the stock over the date range: Mean[ts] 27.9065 

I tried something similar:

Mean[z // Normal]  (I tried with and without Normal) 

The output was the same as the original time series:

I don’t know how to get a list of the dates or values, or to operate on the data.

Can anyone give me a jump start as to how to get into the data that I retrieved from the repository?
