[Commercialization and Food Security Outcomes: chi-square test]

Economic history provides evidence on commercialization of agriculture and its beneficial macro-micro consequences like growth in income, food and nutrition security. This would lead us to the hypothesis that households growing cash crops would be more food secure than the rest. One could explore the association in terms of measures of food insecurity and indicators of commercialization (e.g. cash crop grown). Alternative specifications of food security could be in terms of (i) dependency ratio and number of meals, (ii) average calorie intake per family member or (iii) anthropometric indicator of child nutritional status. Verification of profile essentially involves statistical testing for independence, which can be carried out in terms of chi-square. This topic introduces statistical concepts of independence and homogeneity, and illustrates their applications to food policy analysis. The discussion draws on Chapter 3 of Babu and Sanyal (eds.) (2009).
