2024: Week 16 - Budget vs Actuals

Challenge by: Michał Mioduchowski

We're continuing with DS43's challenges so over to Michał to explain the next challenge. 

_____________________________________

For this week, Superbytes has requested us to look at their budget sheet for 2022. The company believes that their rough budget estimates were very close to the final budget allocations for that year. Examining historical budget data allows the company to identify trends in spending patterns over time. This can provide valuable insights into how expenses have evolved and help predict future expenditure trends. CEO Phil Down would like us to find the exact areas of mismatch between predicted and actual spending.

Inputs

There are 2 inputs for this challenge:
  • Forecasted Spending
 
  • Actual Spending

Requirements

  • Input the Excel file
  • Match Sheet 1 and Sheet 2 in formatting. Both should include:
    • Category field [String]
    • Budget/Actual field [Number (Decimal)]
  • Join both sheets based on Category field to create a single table with 3 columns:
    • Category [String]
    • Budget [Number]
    • Actual [Number]
  • Rename the fields to:
    • Category
    • Forecasted Spending
    • Actual Spending
  • Create a new calculated column with the differences between forecasted and actual values.
    • Values in the new column should be rounded to whole numbers [ROUND(...)]
  • Output the data

Output


  • 4 fields
    • Category
    • Forecasted Spending 
    • Actual Spending
    • Difference
  • 9 rows
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

 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.

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
