2020: Week 37

Challenge by: Jenny Martin

This week we're tackling some questions commonly asked by clients:

How do I calculate working days in Tableau Prep?

or

Is there a networkdays function in Tableau Prep?

Commonly, clients are looking to calculate the number of working days between the open and closing date of support tickets, to see if they're complying with their SLAs. 

However, I thought we'd choose something a bit more fun for the challenge this week! Instead, let's work out how many days you've worked in a specific time period. This could be since you got your first "proper" job, since you started working for your current employer, days you've worked this year - anything you like!

Inputs

The inputs will need to be a little bespoke for this challenge. You will need:

Requirements

  • Input the data
  • Create a row for every date between your start date and today's date
  • Filter out the weekends
  • Perform any necessary cleaning on the bank holiday dataset
  • Exclude bank holidays 
  • Count how many rows you have (being sure to exclude the start date)
  • Remove any holiday days
  • Output the data

Output

I decided to look into the number of days I've worked for The Information Lab! My start date was 1st April 2019, I've taken 26 days holiday in that time and I'm based in the UK. So this is my output, but I'm sure yours will look different.

  • 3 fields
    • Start Date
    • Today
    • Working Days
  • 1 row (2 including headers)
There's no output file to compare against this week, as everyone will have something different!

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

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

How to...Handle Free Text

Image
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
