How can I create a data set with several different categories?

"dataset in excel with the age, sex, and educational attainment of 20 people you know. You can make it up if you have to. Age should be in years, sex should be 'Male' or 'Female', and educational attainment (less than high school, high school diploma, some college or vocational school, college or vocational degree, advanced degree). Provide at least 3 ways to visualize the data."
