2024: Week 49 - Jersey Number Analytics

Created by: Carl Allchin

When watching basketball this weekend, I suddenly started to wonder what is the lowest number that isn't found on any NBA players jersey? Well there's only one way to work that out… data!

But there are other questions that started flowing too:

  • What's the average salary per 10 centimetres grown? (how much should my parents incentivised me to eat more broccoli?)
  • What's the tallest team in the NBA? And who's the shortest team? 
  • Do taller players wear larger numbers?
Just like Week 4 2019 challenge, data preparation tools can often allow us to get to the answers we need. Can you find the answers too?

Input

There's one Excel workbook with 30 individual worksheets:

Requirements 

  • Input the data
  • Combine all 30 worksheets together
  • Answer the following questions through creating separate flows:
    • What's the lowest number not used on a jersey in the NBA?
    • What's the average salary per 10cm of height? 
    • What's the shortest average height team in the NBA? What's the tallest team?
    • Do taller players choose larger jersey numbers?
  • Share your answers with us (and your flow of how you formed them)

Output

This week there are no outputs apart from answers:

1. What's the lowest number not used on a jersey in the NBA?
    38
2. What's the average salary per 10cm of height? 
    1.7m = null
    1.8m = $10.1m
    1.9m = $13.1m
    2.0m = $10.4m
    2.1m = $12.5m
    2.2m = $13.0m
3. What's the shortest average height team in the NBA? What's the tallest team?
    Shortest = Golden State Warriors
    Tallest = Denver Nuggets
4. Do taller players choose larger jersey numbers?
    1.7m = 17
    1.8m = 12.6
    1.9m = 12.7
    2.0m = 17.6
    2.1m = 20.5
    2.2m = 15.3

Here's my flow for reference (without too many clues)

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 & @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!

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 ...
