2019: Week 15

Hi all, after last week's marathon challenge that challenged the creators to find the 'right' answer as much it challenge our "Preppers", I decided to go for a slightly more straight forward challenge this week [insert side-eyes emoji] - it's only easy when you can work it out!

This week, we are putting ourselves in the shoes of a family firm of stock-brokers. The firm has a number of branches across the country, but thankfully they have learned from previous challenges of Preppin' Data, how to put together their lists of their clients purchases. The regulators want to know whether there are any 'weird' behaviour from their clients. Because their client base is quite small, they have agreed to send a file to the regular where the same share has been purchased by multiple customers of the firm. To give the regulator more evidence, they will share what percentage that sale makes up of the whole client portfolio of the firm and within the region.

Requirements


  • Input data
  • Pull a list of clients purchases together across all their regions
  • Determine the % of total sales each transaction makes up:
    • In Region
    • Across the whole firm
  • The final file should only contain sales that are not the only purchase of that share. 

Outputs

  • 11 Columns
  • 1012 Rows (1013 including Headers)
  • No Nulls
For comparison, here's our output files. Don't to forget to fill in our participation tracker!

 Note: Data formed in https://mockaroo.com/ which is brilliant for creating mocked up data to your particular scenario

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
