Big five trait scores for 307,313 people from many different countries.

And remember, keeping screeners under 12 questions is the magic number to prevent attrition.

This is SenseMaker in its most simple form, usually structured to have an open (non-hypothesis) question (commonly referred to as a ‘prompting question’) to collect a micro-narrative at the start. This is then followed by a range of triads (triangles), dyads (sliders), stones canvases, free text questions and multiple choice questions. The reason or value for using Sensemaker: Open free text questions are used at the beginning as a way of scanning for diversity of narratives and experiences. This is a way to remain open to ‘unknown unknowns’. The narrative is then followed by signifier questions that allow the respondent to add layers of meaning and codification to the narrative (or experience) in order to allow for mixed methods analysis, to map and explore patterns.

The aim of this study was to establish if distinct segments were evident in a sexual health context drawing from measures sourced from four segmentation bases extending application of segmentation to all recommended bases [46]. This study indicates how researchers can use two-step cluster analysis to identify segments, which are represented by a group of individuals who share similar characteristics that differ from other groups in the larger heterogeneous target audience. Further, this study demonstrates how available information can be used delivering a dashboard to inform program design and planning.

Small, medium or large — what sample size of users fits your study is a composite question. The magic number of 5 users may work magic in some studies while in some it may not. It depends on the constraints put on by project requirements, assumptions about problem discoverability and implications to the design process. Assess these factors to determine the number of users for your study: What’s the nature and scope of research — is it exploratory or validatory? Who and what kind of users are you planning to study? What’s the budget and time to finish the study? Does your research involve presenting statistically significant numbers or inferring behavioural estimates for the problem statement?

SRI offers an interesting model for segmenting your audience based on their attitudes and values.
