2023: Week 43 - Best Attendance Awards

 Challenge by: Trea McElhone

This challenge is part of the ongoing series related to “Prep” School provided by DS38.

The Prep School is facing an epidemic - too many students are being taken out of class for term time holidays! Thus the staff have come up with their best idea to discourage swapping out Maths class for a ski holiday to Val Thorens, awards for good attendance, because there is no better way to incentivise children than with a laminated sheet of paper and a gold star. These awards will be presented at the end of the school year in the annual Prize Giving Ceremony. As such, the Prep School needs to figure out which pupils are eligible for these awards. First, they want to give year group level awards, with the top 5% of students in each year group receiving this ‘Great Attendance!’ award. Secondly, they want to give a ‘Super Star Attendance’ award to the pupil(s) with the best attendance out of the entire school.

Input

 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.

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 ...
