Sample Size Matters – iOS Behavior Tracking

Sample Size Matters – iOS Behavior Tracking

Share these actual insights

When researching user behavior, one key ingredient to keep in mind is that sample size matters. If researchers want to validate their findings a lot of weight is given to sample size because it is intrinsically connected to statistical significance. In short, statistical significance tells you what the probability is, in percentages, of performing the research again and getting the exact same results as your initial research.

Track Your Happiness

Large online research projects are not new. Three years ago I participated in a research project about happiness. The project, TrackYourHappiness, set out to use modern technologies to collect masses amount of data from random panel members from around the world. On their website we read:

Track Your is a new scientific research project that aims to use modern technology to help answer this age-old question. Using this site in conjunction with your iPhone, you can systematically track your happiness and find out what factors – for you personally – are associated with greater happiness. Your responses, along with those from other users of, will also help us learn more about the causes and correlates of happiness.

The research is still open and you can sign up today.

Here are some results from my latest participation in the project.

Sample Size Matters

Sample Size Matters iconWith Dan Ariely’s latest project, Sample Size Matters, Dan is looking out to the masses of the planet to help him collect behavioral data through the use of iOS apps. On his blog, Dan explains:

By collecting a heaping amount of data (and increasing the size of our samples), we hope to unravel nuances in behavioral variations; we hope to detect the impact of minor differences that simply wouldn’t appear in smaller samples. The pursuit of this app is to collect an abundance of data from an abundance of locations all over the world, shining light on behavioral similarities and differences, from Antarctica to Zimbabwe.

Through this form of crowdsourcing is reaching out to anyone who is willing to help him discover actual behavioral insights.
