convert numeric values in colomn into names

Hi experts,

Here's the situation (probably very easy to solve but could only sort it out for month's, date's etc);

Colomn name: Gender

Values: 0 (=female), 1 (=male)

I want to convert these 0 and 1 into a new colomn with the genders in names instead of numbers so i can make a proper merge in Word.
