In your chosen field, identify a qualitative or quantitative variable that you might want to measure and compare between groups (e.g. from another month or quarter, between different groups or divisions, etc.). Determine the following:

1) Describe the situation (what groups will you compare and what observations or measurements will you be taking), including how and why this would be of interest.

2) Will the data you collect be qualitative or quantitative? This can be tricky! Remember that qualitative data is often collected as "yes/no" data (was a shipment on time, did an employee call in sick, is an employee up to date on required training, etc.) and is summarized in percentages (such as 85% of employees completed training). Quantitative data is a numerical measurement (profit, number of shipments, length of a call, etc.) and is summarized by central tendency.

3) State the null hypothesis for your statistical test, both in words and as an equation.
