Question

Debate the following statement: "Correlation means Causation." Determine whether this statement is true or false, and provide reasoning for your determination, using the Possible Relationships Between Variables table from your textbook. Biddle and Hamermesh (1990) built a multiple regression model to study the tradeoff between time spent in sleeping and working and to look at other factors affecting sleep: Sleep = 0 + 1 totwrk + 2 educ + 3 age + where sleep and totwrk (total work) are measured in minutes per week and educ and age are measured in years. Suppose the following equation is estimated: Sleep = 3500 – 0.15 totwrk – 11.20 educ + 2.29 age + Discuss what would happen to someone’s sleep if they choose to work more. Analyze whether the factors of totwrk, educ, and age are enough factors to explain the variation in sleep. Explain which additional factors should be explored in order to explain the variation in sleep. Provide your reasoning.

Explanation / Answer

An increase in education by one year is predicted to reduce sleep by 11.13 minutes per week The statement, Correlation means Causation is FALSE. Correlation means that that the relation is symmetrical, while in case of causation it is asymmetrical. For example, if x is positively correlated with y, then y is also positively correlated with y. But if x causes y, then it is not necessarily true that y will also cause x. In this case work is negatively related to sleep thus a person who has chosen to work more will have little minutes to sleep per week. Holding other factors constant, an increase to work by one minute will reduce sleep 0.15 minutes per week...
