Emile Durkheim (1858-1917), a founder of sociology, believed that modernization produced social problems such as suicide. He compiled data from several European countries and published Suicide (1897/1951), a book that helped establish quantification in social science disciplines. The data in this problem were created so that the conclusion you reach will mimic that of Durkheim (and present-day sociologists).
On variables such as electricity consumption, newspaper circulation, and gross national product, 13 countries were classified as to their degree of modernization (low, medium, or high). The numbers in the table are annual suicide rates per 100,000 persons. For the data in the table, name the independent variable, the number of levels it has, and the dependent variable. Compute SStot, SStreat and SSerror.
