In one version (as an example) the Index is measured using a battery of parameters like Housing, Income, Work, Community, Social Engagement, Education, Environment, Health, Life Satisfaction, Safety and Work-life balance. These can all be quantified via self-reported values on a Likert-like scale. These kinds of scales are commonly seen, e.g.
My income meets my needs. (choose one of the following)
1. Strongly disagree
2. disagree
3. neither agree nor disagree
4. agree
5. strongly agree
With skilful wording and an appropriate selection of parameters it is possible to get a pretty accurate idea of happiness levels.
Can we agree that self reporting is subjective, not an objective measurement?
One can measure the temperature, or speed of an object. Define "strongly" as used in your post. At which point does disagreement turns into strong disagreement?
First of all, the question is inherently subjective. And by subjective, I mean that the answer will be based on personal knowledge and experience which will be different from person to person.
Secondly, we are not doing numerical measurement, such as temperature, speed, etc. Rather, we are gathering what statisticians call "Categorical Data" which the end goal is typically the percentage or ratio taken from a particular sampling of answers.
So the adjective "strong" helps the study to categorize the sample of answers in more granularity (this may help the research, sometimes it doesn't, depends on the end goal of the research).
And here's how to interpret "strong" in this particular case:
"Strongly agree" could mean that my income is greater than my needs by a large margin. Interestingly, this doesn't tell us whether the income is truly large or the need is truly small.
"Agree" could mean that I don't foresee having difficulty to meet my needs using my income. But if something catastrophic happens, that may change.
"Neither agree nor disagree" means that my situation makes my income sometimes can meet my needs, but sometimes it doesn't.
(Derive the meaning of the other two options based on the above, just in the opposite direction).
But, what if the next person interpret the word "strong" differently?
That could be part of the study to see (for example) whether there is any correlation between the type of interpretations and in what area do the people live, or age group, or many other different factors.
Ain't statistics fun?
