Let’s say we measured two quantitative variables, income per year and the level of happiness.
Income (k) | Happiness
20 | 7
40 | 4
15 | 6
50 | 9
80 | 5
90 | 7
20 | 2
1. Develop a cross-tabulation for the data above. (For income, use 0 as lower limit, 90 as upper limit, and 30 as width. For happiness level, use 1 as lower limit, 9 as upper limit, and 3 as the width)
2. What is your finding about the relationship between income/year and happiness?
