Simple Happiness index (SHI) of a country is computed on the basis of three parameters : social support (S), freedom to life choices (F) and corruption perception (C). Each of these three parameters is measured on a scale of 0 to 8 (integers only). A country is then categorized based on the total score obtained by summing the scores of all the three parameters, as shown in the following table : [Table] Total score 0-4: Very Unhappy; 5-8: Unhappy; 9-13: Neutral; 14-19: Happy; 20-24: Very Happy. Following diagram depicts the frequency distribution of the scores in S, F and C of 10 countries – Amda, Benga, Calla, Delma, Eppa, Varsa, Wanna, Xanda, Yanga and Zooma : [Bar chart transcribed: number of countries (frequency) with each score] Score | S | F | C; 1 | 0 | 2 | 1; 2 | 0 | 1 | 3; 3 | 3 | 2 | 4; 4 | 3 | 1 | 1; 5 | 2 | 3 | 0; 6 | 1 | 0 | 1; 7 | 1 | 1 | 0. Further, the following are known : 1. Amda and Calla jointly have the lowest total score, 7, with identical scores in all the three parameters. 2. Zooma has a total score of 17. 3. All the 3 countries, which are categorized as happy, have the highest score in exactly one parameter.
