2024: Week 34 - The Prep School Birthday Cakes part 3

Challenge by: Jenny Martin

What's this? Our first 3 part challenge! Whilst the Prep School were thrilled with the revised Birthday Cake workflow we produced, they realised there had been an error in missing out one of the Bank Holidays that occur during term time. 

This holiday is the Early May Bank Holiday, taking place on 05/05/2025. This occurs during the Summer, term 5. From last week's solution, anyone who has a birthday on the 5th May is scheduled to have a cake on a public holiday, so we must adapt our workflow to fix this!

Inputs

You can adjust your workflow from last week to meet this new requirement, or download our solution from last week and adapt that. 

The original dataset of student's dates of birth remains unchanged:


The dataset detailing terms and holiday dates, updated to include the 5th May bank holiday. 

2024 Week 34 Input


Requirements

  • Update the input to use the 2024 Week 34 input
  • Ensure that any birthdays on 5th May are rolled back to Friday 2nd May
    • Watch out for duplicate rows!
  • Output the data

Output


3 fields:
  • Cake Needed On Date
  • Cake Weekday
  • Count of Cakes
185 rows (186 rows incl. header)
  • 2nd May should have 16 cakes
  • 23rd May should have 18 cakes

You can view the output here.

After you finish the challenge make sure to fill in the participation tracker, then share your solution on Twitter or LinkedIn using #PreppinData and tagging @Datajedininja, @JennyMartinDS14 & @TomProwse1

You can also post your solution on the Tableau Forum where we have a Preppin' Data community page. Post your solutions and ask questions if you need any help!

For anyone new to the challenges then let us give you an overview how the weekly challenge works.  Each Wednesday the Preppin' crew (Jenny, myself or a guest contributor) drop a data set(s) that requires some reshaping and/or cleaning to get it ready for analysis.  You can use any tool or language you want to do the reshaping (we build the challenges in Tableau Prep but love seeing different tools being learnt / tried).

 Created by: Carl Allchin Welcome to a New Year of Preppin' Data. These are weekly exercises to help you learn and develop data preparation skills. We publish the challenges on a Wednesday and share a solution the following Tuesday. You can take the challenges whenever you want and we love to see your solutions. With data preparation, there is never just one way to complete the tasks so sharing your solutions will help others learn too. Share on Twitter, LinkedIn, the Tableau Forums or wherever you want to too. Tag Jenny Martin, Tom Prowse or myself or just use the #PreppinData to share your solutions.  The challenges are designed for learning Tableau Prep but we have a broad community who complete the challenges in R, Python, SQL, DBT, EasyMorph and many other tools.

We will use dif

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. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in
