Hello everyone,
I have a data set of OECD. I would like to analyse the relation between this two indicators: the relation between unemployment rate and public expenditure on active labour market policies. I have the percentage of unemployment rate and the percentage of GDP dedicate to active labour market policies.

Unfortunately I am not familiar with statistic, but i have to try anyway to give some solutions.
What kind of strategy would you use? For instance, distribution? Regression?

I am using this website to make the calculation http://www.wessa.net/
May you recommend others?
Thank you for your time.
