Connect to the "World Cup Results" and use tables WorldCupMatches, WorldCups. Which of the following year had the highest percentage of Away goals? Consider only those years when the host country did not win the world cup.
In WorldCupMatches table, we have the information of Away goals, and in the WorldCups
table, we have the information of the Winner team and goal scored.
In WorldCups, there is only row for each year. But in WorldCupMatches, there is a separate
row for each match. This is the perfect example to use blend as here we need to first
aggregate the data from WorldCupMatches table.
Let's establish the blend relationship between these two data sources, on the basis of Country
and Year.
Let's use WorldCups as the primary data source, so add the field from this data source to the
view. Drop Year to Rows and change it discrete. Drop Country and Winner field as well to the
rows.
In WorldCupMatches data source, create a calculated field :
Drop this field to the Text, and format it so that it will be shown in percentage.
Out of the given options, only in 1934 host country won the world cup
2010 is the correct answer.
