2024: Week 13 - Easter Sales

Challenge by: Jenny Martin

Chin & Beard Suds Co release Easter themed products each year, 12 weeks before Easter Sunday. Since the date of Easter Sunday changes each year, they have trouble comparing sales to previous years, as the weeks don't line up. They're looking to create the following dashboard to get some insight into their sales in this final week leading up to Easter Sunday. 

Inputs

We have an Excel extract that contains a sheet for each year that C&BS Co have sold Easter themed products.

Requirements

  • Input the data
  • Bring all the years together in a single table
  • Work out the Easter Week Number, as per the first line chart, so the years can be compared
    • Ensure that the weeks begin on a Monday
  • Make sure there is a field for which day of the week each Sales Date is in order to create the 2nd chart
    • Abbreviate these weekday names as above i.e.
      • Monday = M
      • Tuesday = Tu 
      • etc.
  • Add in a field for the Weekday Order so the visualisation can be sorted Monday-Sunday
    • i.e. Monday = 1, Tuesday = 2 etc
  • Calculate the Sales per Product per Sales Date
  • Output the data

Output

  • 9 fields
    • Year
    • Sales Date
    • Easter Week Number
    • Weekday
    • Weekday Order
    • Product
    • Price
    • Quantity Sold
    • Sales
  • 1,752 rows (1,753 including headers)

You can download the output from here. If you want to check your results.

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 ...
