Derived Attribute of 2 Attributes

• Deriving an attribute with 2 attributes allows us to get a derived value in relation to a certain attribute.

• For instance, the average weight for each hair color can be found. It is also important that you place these attributes side by side, such as weight on top and hair color on bottom and have both these selected.

• This shows that people with a higher income tend to spend more.

INFOZOOM

Sorting Two Attributes(Hierarchical Sorting)

• By sorting attributes we can see two attributes in relation to each other.

• This one shows “Gender” per “Income” and done by selecting Income first then Gender.

• From this we can see that the steeper slope in “Income” under “Male” indicates males having a generally higher income.
