There are two data sources/input:

• conjoint_survey_organic.xlsx - Sheet1.csv (source)
• conjoint_survey_ads.csv (source)

The data are generated from this survey. See that survey to find out each question's list of program details.

Need to:

• Filter invalid data: those that answers both "D" ("none of the above") and A-C at the same time.
• Clean and transform data into the following format:

In other words, each question is turned into 3 lines (since there's 3 choice for each line), where the chosen option is set to "1" in column "choice".

Submit here.

The data wrangling is done in clean_data.py in this repo.
