2020: Week 5

Rank in Tableau Prep still isn't as easy as it could be. The Prep Development team have been hard at work and will come up with a solution soon so it's the final chance to try to solve how to do a Standard Competition rank in Prep.

What is Standard Competition ranking? 

This form of Rank is actually the default rank within Tableau Desktop so to be able to mimic it is important. Jonathan showed you how to complete the Modified Competition rank in the Solution post to week 3. Let's look at the differences where the values are 10, 9, 9, 8. 

Standard Competition: 1, 2, 2, 4
Modified Competition: 1, 3, 3, 4

For me, Standard Competition makes a lot more sense as the user (maybe I've been using Tableau for too long) so I really wanted to achieve this in Prep.

The challenge

This week's challenge leads up to one of my favourite sporting tournaments of the year - the Six Nations. For those who don't know, this tournament is where England, France, Wales, Scotland, Ireland and Italy play each other at Rugby. As Preppin' has a global audience, firstly let's handle what is rugby. Well for most of you, I fear the only time you have been exposed to Rugby is in Friends where Ross tries to impress his English girlfriend Emily - it doesn't go well:

To help you all get a bit more perspective on Rugby and the fantastic tournament that is The Six Nations, let's dive into the match results against France - the first fixture for England. You'll need no Rugby knowledge for this challenge. Just know the winner of the game is the team that scores more points (For) than the opposition (Aga - short for against). 

At which venues are England the most dominant team? Let's find their best victory (rank based on largest margin), their worst result and average rank based on the margin of victory / defeat. 

Requirements

  • Input the data
  • Remove the games that have null scores at halftime
  • Determine the Standard Competition rank based on Diff (ie margin of victory - the larger the better)
  • Using that rank give three statistics per rank:
    • Best game Rank per Venue
    • Worst game Rank per Venue
    • Average Rank per Venue
    • Number of Games played at that venue
  • Output the data

Output

  • 5 Columns:
    • Venue
    • Number of Games
    • Best Rank (Standard Competition)
    • Worst Rank (Standard Competition)
    • Avg Rank (Standard Competition)
  • 10 Rows (11 including header)
The outputs can be found here for comparison. Don’t forget to fill the participation tracker and share your solutions using #PreppinData on Twitter.

Created by: Carl Allchin Welcome to a New Year of Preppin' Data challenges. 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). Share your solution on LinkedIn, Twitter/X, GitHub or the Tableau Forums Fill out our tracker so you can monitor your progress and involvement The following Tuesday we will post a written solution in Tableau Prep (thanks Tom) and a video walkthrough too (thanks Jenny) As with each January for the last few years, we'll set a number of challenges aimed at beginners. This is a great way to learn a number of fundamental data preparation skills or a chance to learn a new tool — New Year&

 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
