Count rows within a column

[Anonymous]

Hi, 

How do I create a measurement that calculates the amount of rows within a column, but ignores if the same name is repeated.

For example:

In the following column, there is 13 names, but only 4 that is different. Currently when this is calculated the calculation says 13, but how do I do if I want to ignore repeated words?

Regards,

Albin
