The steps below are best practices for making data requests. Data owners are frequently overburdened with daily operations. You can make it as easy as possible for them to fulfill your request by planning carefully and addressing all of the relevant questions up front.
Before you can make an effective data request, you need to know exactly what you are looking for and why. Below are some questions to answer before moving forward.
Knowing what you want before turning to data is a prerequisite to effective data use. For tips on writing goals and objectives that map clearly to specific types of data, see Appendix A: Setting SMART goals.
If you are conducting an experiment, then the data might be response statistics. If you are looking through financial or budgetary data, it might be spending trends, projections, and forecasts. Other situations will call for other kinds of measurements, but thinking about what you expect to find — or even the kind of answer you are looking for — will help you identify the most relevant metrics. Some examples of suitable research questions for your data include:
In the age of “big data” it may be tempting to collect as much information as possible and sort through it later. But this approach is counterproductive. Looking at too many metrics may overwhelm the analysis or distract you with red herrings that don’t actually address your question. And requesting more data than you need from a sister agency would make responding to your request more time consuming. Some suggested methods of reducing the data you have to sift through include:
Solving a series of subproblems is almost always easier than solving a whole problem at once, and data analysis is no different. Can you segment your problem into smaller steps and use different facets of the data to answer sub-questions?
In particular, what’s a good “first step” to tell quickly whether or not you are on the right track? (This is called “failing fast,” which is a good practice to save time and energy by weeding out solutions that won’t be productive.)
Once you’ve identified the data source, reach out for any standardized processes the agency may have for making data requests. Each agency will have their own process.
Data owners are accountable for the proper use and security of their data. In order to evaluate the risks and benefits of sharing data, they will require an explanation of how you plan to protect and use it. The data owner’s agency will have its privacy and security processes, and your practices will need to comply with them. When requesting data, you should be prepared to explain:
An effective data request starts with a clear description of why the requested data is important to both parties’ missions and what you plan to achieve with the data. Understand the data owner’s possible motivation to take on the data sharing project:
To ensure full and sustained participation, each party involved in the data sharing effort should be able to see direct benefits from their involvement.
It may also help to think about how you will respond if your first request is denied. Here are some common reasons data providers deny requests according to the National Neighborhood Indicators Partnership:
The data owner needs to understand exactly how to fulfill the request. Some useful parameters or filters to consider include:
Ensure that the data owner can fulfill the data request in a reasonable timeframe and with their available resources. If a data request is too taxing on the data owner, they may reject the request until the parameters change or the requester offers additional resources. Consider the time required for crafting and signing a data sharing agreement.
