Which of the following is an example of tidy data?

complicated JSON from facebook API
complicated JSON from Twitter API
unformatted excel file
all of the mentioned

The correct answer is: none of the mentioned.

Tidy data is a data format that is easy to work with. It has four key properties:

  • Each variable has its own column.
  • Each observation has its own row.
  • Each value is atomic (i.e., not a list or other complex data structure).
  • Each column has a meaningful name.

Complicated JSON from Facebook API, complicated JSON from Twitter API, and unformatted excel file do not meet all of these properties. Therefore, they are not examples of tidy data.

Here is a more detailed explanation of each option:

  • A. Complicated JSON from Facebook API: JSON is a data format that is often used to transmit data between web applications. It is a text-based format that is easy to read and write. However, JSON can be very complex, and it can be difficult to work with if it is not well-formatted.
  • B. Complicated JSON from Twitter API: Twitter API is a RESTful API that allows developers to access data from Twitter. The API returns data in JSON format. As with any JSON data, it can be difficult to work with if it is not well-formatted.
  • C. Unformatted excel file: Excel is a spreadsheet program that is commonly used to store and analyze data. Excel files can be very complex, and they can be difficult to work with if they are not well-formatted.

In conclusion, none of the mentioned options are examples of tidy data.
