In this project, we'll clean and analyze exit surveys from employees of the Department of Education, Training and Employment (DETE)}) and the Technical and Further Education (TAFE) body of the Queensland government in Australia. The TAFE exit survey can be found here and the survey for the DETE can be found here.
We'll pretend our stakeholders want us to combine the results for both surveys to answer the following question:
Are employees who only worked for the institutes for a short period of time resigning due to some kind of dissatisfaction? What about employees who have been there longer?

We can make the following observations based on the work above:
The dete_survey dataframe contains 'Not Stated' values that indicate values are missing, but they aren't represented as NaN. Both the dete_survey and tafe_survey contain many columns that we don't need to complete our analysis. Each dataframe contains many of the same columns, but the column names are different. There are multiple columns/answers that indicate an employee resigned because they were dissatisfied.

There aren't any major issues with the years. The years in each dataframe don't span quite the same number of years. We'll leave it up to your discretion to drop any years you don't think are needed for the analysis.
