2023: Week 19 - TC Special

Challenge By: Carl Allchin

Welcome to the Tableau Conference Special for Preppin' Data. If it's your first time here then a very walk welcome to you! This week we have something pretty special planned for you with a 3 part challenge. The output for each part will flow through to the next part, allowing you to build to answer the ultimate question: Who is the person your boss has tasked you with finding and where are they?!

The only information your boss has given you is that they're presenting about data deduplication on the 2nd floor. The rest is up to you!

Beginner Level

Input

The input for this challenge contains all the information about sessions. The presenter name, the subject and a detailed description are all squeezed into one field that we'll need to parse out.

Requirements

Hint: String functions will be super useful for this challenge, learn more about them here
  • Input the data
  • Split out the Description field into Speaker Name and Presentation Description
  • Create the initials for each speaker
    • e.g.  Jenny Martin becomes JM
  • Categorize the Presentations into the following Subject areas:
    • Prep
    • Server
    • Community
    • Desktop
  • Create a Boolean (True/False) field for identifying talks that mention deduplication 
  • Filter to on talks that mention deduplication
  • Remove unnecessary fields
  • Output the data

Output 1


  • 4 fields
    • Subject
    • Speaker
    • Session Number
    • Deduplication Flag
  • 3 rows


Intermediate Level

Input

This next input will join onto Output 1. It may need some reshaping first though to help us work out which 2nd floor sessions are about deduplication.

Requirements

  • Input the data
  • Pivot the data so the Room and Floor number are on the same row
    • Filter out any unnecessary rows
    • Rename fields
  • Create a room number that also gives detail of the floor number
    • e.g. Room 2 on Floor 1 will be Room 102
  • Split out the Session Detail field into Session Name, Speaker and Subject
  • Join with Output 1
  • Filter to the session on the 2nd floor
  • Remove unnecessary fields
  • Output the data

Output 2


  • 4 fields
    • Speaker
    • Subject
    • Session Number
    • Room
  • 1 row


Advanced Level

Input

The final input will join onto Output 2. It contains a distance matrix (in meters!) between rooms. Use this to work out how long it will take you to reach the person you need to talk to.

Requirements

  • Input the data
  • Reshape the data so we have a column for Room A, a column for Room B and a column for the distance between them (in meters)
  • Exclude null rows
  • Exclude values between the same room
  • Assume you have a walking speed of 1.2 m/s. How many minutes will it take you to travel between rooms?
    • Round up to the nearest whole minute to account for busy conference corridors
  • Join to Output 2
  • You're currently in Room 302, how long will it take you to reach them?
  • Remove unnecessary fields
  • Output the data

Output 3


  • 6 fields
    • Room A
    • Room B
    • Minutes to the next room
    • Metres
    • Speaker
    • Subject
  • 1 row
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!

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 u...

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 ...
