I need help with business statistics work using excel and the necessary fucntions. Please guide me as much as possible,

By using this excel data how can I Calculate summary measures (average, median, st. dev., min, max, 25th percentile, 75th percentile, and count) of the variable Percentage Change using Excel. For percentile, I was instructed to use an inclusive function.NOTE this is just an example of data I just need the functions of measures to start.
