2022: Week 20 - TC22 Session Attendance

 Challenge by: Jenny Martin

It's time for TC22 and in celebration of the hybrid virtual and in person conference this year we're bringing you a TC themed challenge! We want to compile a list of those who were unable to attend the sessions they registered for. 

If you're new to the Preppin' Data challenges then welcome! We've included some extra hints for this challenge to help you get started, and would recommend going back to the beginning of the year for some more information about what Preppin' Data is all about.

Inputs

We have 4 input datasets for this challenge:
  1. Registrations 

  2. Sessions Lookup Table 

  3. Online Attendees 

  4. In Person Attendees

  • Input the data
  • In the Registrations Input, tidy up the Online/In Person field (hint)
  • From the Email field, extract the company name (hint)
    • We define the company name as being the text following the @ symbol, up to the .
  • Count the number of sessions each registered person is planning to attend (hint)
  • Join on the Session Lookup table to replace the Session ID with the Session name (hint)
  • Join the In Person Attendees dataset to the cleaned Registrations
    • You will need multiple join clauses
    • Think about the Join Type, we only want to return the names of those that did not attend the sessions they registered for
  • Filter to only include those who registered to be In Person (hint)
  • Join the Online Attendees dataset to the cleaned Registrations
    • You will need multiple join clauses
    • Think about the Join Type, we only want to return the names of those that did not attend the sessions they registered for
  • Filter to only include those who registered to be Online
  • Union together these separate streams to get a complete list of those who were unable to attend the sessions they registered for (hint)
  • Count the number of sessions each person was unable to attend (hint)
  • Calculate the % of sessions each person was unable to attend (hint)
    • Round this to 2 decimal places
  • Remove unnecessary fields 
  • Output the data

How to...Handle Free Text

Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell.
