Sociologists often study the dominance of one group over another. Suppose in a certain society there are four classes which we will call: abigweel, aweel, upancomer, and pon. Hint: These are pronounced "A big wheel," "A wheel," "Up and comer," and "peon." ? Abigweel dominate aweel, upancomer, and pon. Aweel dominate upancomer and pon. Upancomer dominate pon. ? Matrix [ D ] represent these dominance relationships. We say that an individual has two-stage dominance over another if 1 appears in the matrix [ D ] 2 for those individuals. Write the two-stage dominance matrix. ?
