D)-.67. 153)The weakest relationship, as indicted by these correlation coefficients, is: A)+.27. B)-.74. C)-.35. D)+.16. 154)A researcher finds that there is no correlation between the colour of the house you grew up in and your IQ. This relationship, as indicted by these correlation coefficients, is: A)-.35. B)0.0. C)+.27. D)-1.00. 155)A researcher finds that there is no correlation between the colour of the house you grew up in and your IQ. This relationship, as indicted by these correlation coefficients, is: A)+10.00. B)-10.00. C)0.0. D)-1.00. 156)Which of the following statements about correlation is true? A)Positive correlations are meaningful, but negative ones are not. B)A strong correlation is indicative of a causal relationship between variables. C)Correlations close to +1.0 or -1.0 are strong, while correlations close to 0 are weak. D)Negative correlations are weak, but positive ones are strong. 157)The number of storks nesting in some European villages is positively correlated with the number of human births in the villages. This means that: A)when many storks are nesting in the villages, researchers may predict fewer human births. B)the researchers made an error in their calculations since babies don’t attract storks! C)since storks don’t bring babies, one may assume that correlation never represents causation. D)the number of human births may be predicted by knowing the number of stork nestings. 158)The higher a male monkey’s level of the hormone testosterone, the more aggressive he is likely to be. This means that: A)testosterone causes aggression. B)testosterone and aggression are negatively correlated. C)testosterone and aggression are uncorrelated. D)testosterone and aggression are positively correlated. 159)The higher a male monkey’s level of the hormone testosterone, the less docile he is likely to be. This means that: A)testosterone deficiencies cause docility in monkeys. B)testosterone and docility are negatively correlated. C)testosterone and docility are positively correlated. D)testosterone and docility are uncorrelated. 160)The hotter the weather, the more muggings tend to occur. This means that: A)hot weather and crime are uncorrelated. B)heat causes violent behaviours. C)hot weather and crime are positively correlated. D)hot weather and crime are negatively correlated.
