Define if there is a difference among the income of the adults using One-way ANOVA.
The subsequent study was developed by Economist Simon Fass. Fass plotted a sample population of low-income households in St. Martin. The variables analysed were monthly income per adult as well as choice of rental contract for housing.
All families in St. Martin had to opt for one of 3 available time packages. They could pay in advance for a week a month or six months and the shorter the time package the higher the unit price. Payment by the week cost 10 to 20 percent additional in monthly rent per square meter than payment by the month as well as payment by the month cost twice as much as for 6 months. However offsetting the higher unit cost was the advantage of lower cash outlays. To attain a week of housing required an average prepayment of $1.55. A month cost $5.30 and 6 months $18.90 (Fass 1987)
You necessity determine if there is a difference among the income of the adults in respect to the housing contract they choose. Might the data of income be drawn from the same population or are we possibly looking at two or maybe three different sample population.
