How Survey Insights Are Calculated

Wellio Insights reports give schools a data-driven approach to improving student wellbeing over time. Understanding how these results are calculated helps schools make informed decisions about what to do next.

Glossary of Key Terms

Baseline Survey: A comprehensive survey conducted once or twice a year.
Trend Survey: A shorter follow-up survey analysing specific targeted factors.
Wellbeing Factor: A specific category or theme that serves as a key driver of wellbeing.
Favourability Percentage: The percentage of students that responded favourably to a question (answering either “Agree” or “Strongly Agree”).
Index Score: A single percentage summarising overall results across all respondents.
Factor Score: The average favourability percentage for all questions linked to the factor.

1. How Individual Student Responses Become Scores

Wellio surveys primarily use a five-point Likert scale:

Strongly Agree
Agree
Neutral
Disagree
Strongly Disagree

Individual student responses are grouped into categories and rolled up to create meaningful measures of student wellbeing on an individual-, cohort- and school-wide level.

How we group student responses to individual questions.

The number of “Favourable” responses (“Agree” or “Strongly Agree”) are divided by all responses to create a Favourability Percentage for each question.

2. Survey Structure - What are Factors?

Each survey is structured around factors. Each factor is associated with multiple related questions.

Two types of factors are used in Wellio surveys:

Outcome Factor: This is the first factor measured for each survey, and is rolled up across cohorts to calculate the overall Index Score. The Outcome Factor’s questions are designed to measure overall outcomes at a high level.

Driver Factor: All other factors included in the survey. These drivers provide guidance into specific areas of focus that support improving the overall Index Score.

3. Index Score Calculation

Sample Index Score from the Wellbeing Skills Index Survey

The Index Score is a single percentage value (out of 100%) that summarises the Outcome Factor scores across all respondents from each cohort.

Sample outcome questions from the Wellbeing Skills Index Survey

A greater proportion of favourable responses to Outcome Factor questions leads to a higher overall Index Score.

4. Factor Score Calculation

Each Factor Score is a single percentage (out of 100%) that averages the favourability percentage across each of that factor’s specific questions, for each cohort.

Within your survey report, the Heatmap tab displays Factor Scores, as well as the favourability percentage for each question.
