 Qualitative/nominal 

Gender is expressed as qualitative and nominal. Qualitative because it doesn't have a number, so it's not quantitative. It also nominal because gender is considered as having the same level. Another example of nominal is blood group or religion.
If it has an order of level(example: severity mild to severe), it will be ordinal.
