Exam 4: Classifying Research

A study of juvenile delinquency reveals a strong correlation between illegal drug use and delinquent acts. The researcher concludes that illegal drug use is the cause of delinquent acts. Looking at the same data, another researcher comes to the conclusion that delinquent acts lead to illegal drug use. Which causal rule are both researchers forgetting here?

If 'A' happens before 'B' and there is a predictable correlation between these two variables, is that enough to conclude that 'A' is a cause of 'B'?

A teacher who observes a small group of minority students talking loud in the hallway and concludes that young minorities are taught to talk loudly is making what type of logical error?

A recent analysis of vehicular burglaries in a northern city reveals that, on average, there are 25 vehicular burglaries throughout the city each month. About as many occur during the winter months as do during the summer months. In this case, we would say which of the following about the correlation between temperature and vehicular burglaries?

A teacher who reads a research report finding that minority students tend to speak loudly and concludes that each minority student in her classroom must be told to speak softly in the classroom is making what type of logical error?

The causal rule that the cause must precede (happen before) the effect is referred to as:

After observing their behavior for several months, a researcher theorized that correctional officers become personally detached from inmates as a means of reducing the stress associated with their professional responsibilities. What method of reasoning is this researcher using?

If body weight decreases after sustained physical exercise, then the correlation between body weight and calorie intake is:

A recent analysis of aggravated assaults in a northern city reveals that aggravated assaults tend to increase during the warmest months of the year and decrease during the coldest months of the year. In this case, we would say which of the following about the correlation between temperature and aggravated assaults?

A researcher conducts a secondary analysis of census data to understand how different counties in one state compare with respect to rates of poverty. What is the researcher's unit of analysis?

You have completed a study on the alleged causal relationship between the moon phase and street crime. You determined that there is no correlation between the phase of the moon and the rate of reported street crimes, despite the fact that many of your colleagues in the police department strongly believe there is. Your research reveals that the relationship between the moon phase and street crime is:

A researcher finds a strong and positive relationship between drug use and criminal behavior. With this information alone can the researcher conclude that drug use is the cause of criminal behavior?

Because the research suggests that police officers are more likely as a group to experience alcoholism, the chief of police concluded that Officer Smith's recent illness was likely caused by his excessive drinking. Which type of logical error did the chief of police commit?
