Day 7 - Secondary Research

Data collected through existing means to help support decisions and define other areas.

What I Learned:

While it seems like a simple, college level concept to "google" or look up existing sources of information, this chapter helped define different types of research for me. I learned that secondary research is referred to as "desk research" while the primary is the "field work" portion. This helped me to know that much of what is done in research is primary. That said, secondary research can be employed to help back-up the primary findings and provide a way to find "...opportunity gaps."


When I've previously designed iPhone interfaces, I've used a template of the iPhone 7 or 8. Why? Because I once learned that while there may be brand new iPhones (iPhone X and 11), the majority of the customer base is using an older model (iPhone 7 or 8). Knowing that I've usually designed towards the majority of users.

In this practice, I wanted to reaffirm the design choice of designing for an iPhone 7/8 interface so I did some secondary research to find sources that can give more insight into this.


This site is trusted by the likes of Google, Adobe and Paypal, so it seemed like a credible source to get information from. They had a published breakdown of iPhone model users for 2019.

Device Atlas

Another seemingly credible source that is used by Adobe, Netflix, Verizon. Device Atlas takes the information a step further in reporting a breakdown of the countries and their statistics of device ownership. This secondary research can help in identifying what interface to use depending on the region you're designing for.

Comparing the data from both of these secondary sources allowed me to confirm the iPhone ownership in 2019. Both sites had sources for their findings and non-conflicting data about ownership.
