# Core Designer Certificate

Solved!
Level 2
###### Core Designer Certificate

Hi Experts,

I am new in DataIku, just passed 101, 102, 103 learning passes, and am already fascinated by unlimited capabilities, which the platform gives to non-coding analysts. It`s gorgeous!

Now I am passing Core Designer Certificate exercise and stuck on Hands-On instructions step 5 :

"Some columns ( Oil production (Etemad & Luciana) (terawatt-hours), meat_prod_tonnes, and Food Balance Sheets: Eggs - Production (FAO (2017)) (tonnes) ) report country total data. Transform these three columns into per-capita data."

I applied  formula: "numval("Oil production (Etemad & Luciana) (terawatt-hours)") / numval("Population), but it`s not correct.

I tried to find correct formula to apply for this task, checked the materials, provided on the "Formula page" reference, but cannot work out right formula.

Many thanks.

Respectfully,

Vyacheslav

when you say your formula is not correct.  What do you mean

- the formula is producing a error message.  If so what is the error message.
- or are the numeric results incorrect.

In the example above I notice an extra quote mark “ before the formula.  I also note you are missing a quote mark “ after population and before the closing parenthesis ).

Regarding univariate analysis, I’m not clear exactly what type of data you are working with or which type(s) of univariate analysis you are trying to do.

That being said there are a bunch of tools built into Dataiku for exploratory data analysis that might be useful to you. As a starting point you might find the statistical worksheets to be useful. Here is a knowledge base article on the use.

Here is a link to the documentation.

You can do all sorts of other types of analysis with Dataiku and then even more type using R Jupiter notebooks and Python.

Have fun with your data.

Good day, Tom,

Thanks a lot for your feedback and suggestions.

I adjusted the formula syntax details as was recommended and it worked out well.

Your help is highly appreciated.

Now could you please advise where I can find explicit instructions how to create an univariate analysis?
