2020: Week 41

Challenge by: Carl Allchin

Welcome to Tableau Conference-ish! Every year we like to create a special conference focused challenge. This year is no different. We can't meet in person this year so instead we've arranged to capture the zoom logs of comments from the prep focused session at the Conference. 

We want to understand who attended and how many questions and answers were delivered through this format. Can you help us understand that? The names are either fictions or some of our regular Preppers who we really wanted to hang out with at the conference so if you see your name - we miss you! (or couldn't think of anyone else from that location). 

Inputs

One file but a few sheets:

Individual session logs that look like:

There are three sessions: one for APAC, one for EMEA and one for AM (the Americas).

Requirements

  • Input sheets
  • Make a date time field to represent local time (it will be useful later). The session was on 7th October 2020 at 2pm for everyone.
  • Make sure you know which comment came from which session
  • Split the comments into two:
    • Everyone's first comment (except Carl Allchin's) is saying where they are from and whether it's their first session
    • Every subsequent comment is either a question or answer
  • Work out where people are from for cities and countries. 
    • Clean up any rogue values
    • EMEA and APAC list their city and country
    • Folks from AM list their city and country unless they are from the US where they list their city and state. Feel free to add in the country as the United States rather than the State.
    • Apply a data role of city and country and ONLY return VALID results (sorry Rosario, Jenny and others!)
  • Count the number of questions and answers at each session excluding everyone's first comment
  • Work out the times to make them all equal Greenwich Mean Time (GMT)
    • APAC is 11 hours before GMT
    • EMEA is 1 hour before GMT
    • AM is 5 hours after GMT
  • Output two data sets

Output

Two files:
1. Who attended?



6 Data Fields:
  • Date in GMT
  • Location
  • City
  • Country
  • Attendee's First Time?
  • Who?
33 Rows (34 including Headers)

2. How many Questions and Answers?
3 Data Fields:
  • Instances
  • Question or Answer
  • Location
6 Rows (7 including Headers)

Here is the Output files to let you check your structure.

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, @JonathanAllenby & @TomProwse1

You can also post your solution on the brand new 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 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
