The World Value Survey (WVS)

The World Value Survey (WVS) is a multi-country survey. One question they ask of their respondents is about their subjective happiness: “Taking all things together, would you say you are: 4. Very happy 3. Rather happy 2. Not very happy 1. Not at all happy.” In the most recent survey in Sweden the answers to this question distributed themselves as in Table 2. So, for instance 488 respondents answered that they were very happy. Please calculate the mean, median and mode. Which of these three measures of central tendency do you prefer for this particular variable?
