Patent Licensing Form

I created these forms for Ohio State University's patent licensing office when government regulatory changes required a shift in reporting procedures. The form allowed the compliance officers to efficiently obtain the required details from the licensing officers, then use the generated data to complete their reports in a timely manner.Tools: Microsoft Forms


Top 20 Video Games

My husband wanted to make a compilation video of our friends' most beloved video games of all time. He invited everyone to send in their top 20 lists.I took charge of collecting and organizing the data. I used Excel to answer some questions I was curious about:
- Which games were the most popular?
- How popular were the games chosen by each person?
- How many games were exclusive to each person?
- What was the correlation like between different people?
- Which games did [person 1] and [person 2] have in common?
