13.3. Studio: Introduction To Data

13.3.1. Getting Started

You will be working in a small group to discuss a potential data analysis project. Your course staff will give each group a scenario which outlines the business issue and what data you have at your disposal. Before you dive in, give everyone in your group time to read through the scenario and discuss it so that everyone is on the same page. Don’t hesitate to ask course staff any questions you may have about your scenario! Use the Exercises as a guide for the discussion and make sure to leave yourselves time to put together a small presentation reviewing your discussion for the class.

In your presentation, make sure to include:

  1. The problem the business owner is trying to solve.

  2. Available data sources? What kind of information do we need?

  3. What would you need/do to prepare the data? Problems with the data?

  4. Talk about exploratory analysis and KPIs.

  5. Discuss what would make your results valid/invalid.

  6. Who are the stakeholders and how would you present your findings?

13.3.2. Scenarios

Cierra is a young woman in her 20s. She has over 250,000 followers on her knitting instagram, @cierraknits. She and her manager want to take a closer look at where she is earning money and how much. They are tasking you with figuring out if Cierra makes more money writing and selling her knitting patterns herself on Ravelry or writing knitting patterns for sponsors, such as Yarniverse, which are offered through their site. Cierra and her manager are also wondering if factors such as time it takes her to finish a project and whether or not a sponsor gifts her the yarn have an impact. At the end of the project, you will be presenting your findings to Cierra and her manager.
