I can use views conditional to add a field depending on the content type, but how do I add a style to the entire row of content depending on the content type, for example I want content of type Article to have a class so that I can color it blue, while content of type "statistical data" will be white .

This class fields accepts views tokens (though does not provide the overview of them). So you should add a field for the content type, hide it from display if you please. Discover the token name of this field by checking the rewrite section and finally place this token in the row class field.
In my example I use the value of a php field to add row classes:
