| Symbol | Explanation |
| DM | DIFFERENCE of MEANS Type: descriptive statistic only. Measurement level: Correlate: dichotomous, Happiness: metric Range: depending on the happiness rating scale of the author; range symmetric about zero. Meaning: the difference of the mean happiness, as measured on the author's rating scale, between the two correlate levels. |
| OR | OR: Odds ratio in binary logistic regression. Happiness is a binary or dichotomous variable with Happy =1 and Unhappy=0. OR < 1 indicates that the odds of being happy-to-being unhappy decreases by a factor OR when 1) the corresponding metric correlate increases by one unit 2) the corresponding category of a categorical correlate is compared to the reference category. OR > 1 indicates an increase by a factor OR for both the above cases. |
