# Independent Sample t test

I am having a hard time understanding how to perform t-tests in nonnumerical data.

A. Perform two t - tests to determine if there is a difference in your spending category based on Card Type or Reward Type.

Do people who get World Points spend more than those who get Gas Rebates on your Spend type?
Do people with Master Cards spend more than those with Visa Cards on your Spend type?
