2021: Week 41 - Southend Stats

Challenge by: Jenny Martin

I was talking to a friend the other day who is a big football fan, but unfortunately their team hasn't been doing too well in recent years. They support a local team called Southend United and my ears pricked up when he claimed they've only won 18 games in the last 108 that they've played. My initial intention with this challenge was to investigate this claim, but instead I stumbled upon historical data which I though might help him to feel a little better and remember the good times.

Input

We're using the Football Club History Database for our data this week:

Requirements

  • Input the data
  • Rename the penultimate column from P 1 (as it appears in Prep) to Pts
  • Exclude null rows
  • Create a Special Circumstances field with the following categories
    • Incomplete (for the most recent season)
    • Abandoned due to WW2 (for the 1939 season)
    • N/A for full seasons
  • Ensure the POS field only has values for full seasons
  • Extract the numeric values from the leagues
    • FL-CH should be assigned a value of 0 
    • NAT-P should be assigned a value of 5
  • Create an Outcome field with 3 potential values. (Note: this should apply to all seasons in the data order regardless of any gaps. The current season will have a null value)
    • Promoted, where they are in a league higher than their current league in the following season
    • Relegated, where they are in a league lower than their current league in the following season
    • Same League, where they do not change leagues between seasons
  • Create new rows for seasons that were missed due to WW1 and WW2
  • Update the fields with relevant values for these new rows
    • e.g. change their Special Circumstances value to WW1/WW2
  • Output the data

Output

  • 12 fields
    • Season
    • Outcome
    • Special Circumstances
    • League
    • P
    • W
    • D
    • L
    • F
    • A
    • Pts
    • POS
  • 116 rows (117 including headers)

 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 love seeing people learn new tools so feel free to use whatever tools you want to complete the challenges.  A New Year means we start afresh so January's challenges will be focused on beginners. We will use dif

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
