A)The two variables will be positively correlated. B)The first variable causes the second variable. C)The two variables will be negatively correlated. D)The two variables will be uncorrelated. 132)Two sets of observations, assessing annual income and dental health, are compared. Which of the following is the most likely outcome? A)The two variables will be positively correlated. B)The two variables will be uncorrelated. C)The two variables will be negatively correlated. D)The first variable causes the second variable. 133)Two sets of observations, assessing hours spent watching television and grade-point averages, are compared. Which of the following is the most likely outcome? A)The two variables will be negatively correlated. B)The first variable causes the second variable. C)The two variables will be uncorrelated. D)The two variables will be positively correlated. 134)Two sets of observations, assessing age and the number of hairs on a man’s head, are compared. Which of the following is the most likely outcome? A)The first variable causes the second variable. B)The two variables will be positively correlated. C)The two variables will be uncorrelated. D)The two variables will be negatively correlated. 135)Two sets of observations, assessing shoe size and IQ, are compared. Which of the following is the most likely outcome? A)The two variables will be uncorrelated. B)The two variables will be negatively correlated. C)The first variable causes the second variable. D)The two variables will be positively correlated. 136)A researcher is interested in whether there is a relationship between musical ability and mathematical ability. The type of design best suited to this task would be a/an: A)case study. B)correlational study. C)survey. D)naturalistic observation. 137)It is quite likely that the more classes students miss, the lower their test grades tend to be. This relationship illustrates a/an: A)coefficient of correlation. B)positive correlation C)zero correlation. D)negative correlation 138)Professor Holden gives a psychology exam on the origins of intelligence. She gives a short answer question based on the IQ scores of a parent–child pair. In order to answer the question correctly, her students need to remember that: A)given these variables, the correlation will be positive. B)to say that a relationship exists, you need more than one pair of values to compare. C)given these variables, the correlation will be uncorrelated. D)given these variables, the correlation will be negative. 139)Dr. Myers found that students in her class who scored 80% or better on the mid-term exam were likely to score 70% or better on the final exam. Students who scored below 60% on the midterm, however, were likely to end up failing the final exam. These test results suggest: A)there is a strong negative correlation between the midterm and final exam scores. B)students who do poorly on the midterm exam give up and fail to study adequately for the final exam. C)the midterm and final exam scores are not correlated. D)there is a strong positive correlation between the midterm and final exam scores. 140)Imagine that the personality traits of conservatism and aggression have a strong negative correlation. If Sue has a score on aggression that is very low: A)it is impossible to predict her score on the conservatism scale without more information. B)she will likely have an average conservatism score. C)she will likely have a high score on conservatism. D)she will likely have a low score on conservatism.
