While many of these fields mostly utilize the combination of qualitative and quantitative data, history adds another layer of data when it comes to working with historical objects. Often, the condition of historical artifacts counts as data. This may include the condition of the object, the measurements of that object (ex. height, weight, etc.), the texture of an object, or any markings/engravings that may appear. In this way, archives become an important source of data for historians to utilize when searching for questions outside of the contents of the documents or objects they study.
While communications/public relations data can vary depending on the situation, this discipline (alongside history, political science, and sociology) are disciplines that traditionally seek to understand how biases impact everyday life. Data is no different, as how humans collect, analyze and communicate data is often filled with many biases (in other words, data does not speak for itself). Being aware then of those presenting data and considering some of the biases and perspectives that go into the lifecycle of that data are critical skills to become literate in any data field.
