Correlations are an improvement over case studies because from correlations we can determine:
-
The reliability of a relationship
-
Cause and effect
-
Whether a third variable is responsible for the relationship
-
The effecdts of a dependent variable
Correct Answer
A. The reliability of a relationshipExplanation
Correlations are an improvement over case studies because they allow us to determine the reliability of a relationship. By analyzing the correlation coefficient, we can assess the strength and direction of the relationship between two variables. A strong correlation indicates a more reliable relationship, while a weak correlation suggests a less reliable relationship. Therefore, correlations provide a quantitative measure of the extent to which two variables are related, offering more robust evidence compared to case studies which often rely on qualitative observations and individual cases.Rate this question:

A correlation coefficient can be used to determine whether:
-
There is a relationship between two variables
-
Changes in one variable cuase changes in another variable
-
One variable confounds another variable
-
The relationship between two variables due to a third variable
Correct Answer
A. The relationship between two variables due to a third variableExplanation
A correlation coefficient measures the strength and direction of the linear relationship between two variables. It indicates how closely the variables are related to each other. In this case, the answer suggests that the correlation coefficient can be used to determine the relationship between two variables, but specifically, when that relationship is influenced or caused by a third variable. It implies that the correlation coefficient can help identify whether the relationship between two variables is direct or if there is another variable playing a role in their association.Rate this question:

Levels and education and income are generally
-
Positively correlated
-
Uncorrelated
-
Negatively correlated
-
Perfectly correlated
Correct Answer
A. Positively correlatedExplanation
The term "positively correlated" indicates a relationship where two variables tend to increase or decrease together. In the context of levels of education and income, a positive correlation suggests that as the level of education increases, the income level also tends to increase. This means that individuals with higher levels of education generally have higher incomes.Rate this question:

Which of the following correlations indicates the weakest relationship between two variables?
-
-.22
-
+.65
-
-.74
-
+.19
Correct Answer
A. -.74Explanation
The correlation coefficient measures the strength and direction of the relationship between two variables. A correlation coefficient of -.74 indicates a strong negative relationship between the variables. As the absolute value of the correlation coefficient increases, the strength of the relationship also increases. Therefore, the correlation coefficient of -.74 indicates the strongest relationship among the given options.Rate this question:

In experiments, participants are randomly assigned to conditions to avid:
-
Placebo effects
-
Differences between the gruops that are due to the independent variable
-
Experimenter expectations
-
Differences between the groups that are not due to the independent variable
Correct Answer
A. Differences between the gruops that are due to the independent variableExplanation
In experiments, random assignment of participants to conditions helps to avoid differences between the groups that are due to the independent variable. By randomly assigning participants, any potential confounding variables or differences between the groups can be minimized. This ensures that any observed differences between the groups can be attributed to the independent variable being studied, rather than any other factors. Random assignment helps to create comparable groups, increasing the internal validity of the experiment.Rate this question:

A good way to study the effects of genetic factors on aggression would be to:
-
Compare the elvels of agression across different biological families
-
Do a longitudinal study in which agression is mesaured over a long period of time
-
Compare the levels of agression in adopted children to the levels of agression in their biological and their non biological parents
-
Study the similarities among adoptees and their biological parents
Correct Answer
A. Compare the levels of agression in adopted children to the levels of agression in their biological and their non biological parentsExplanation
To study the effects of genetic factors on aggression, comparing the levels of aggression in adopted children to both their biological and non-biological parents would be a good approach. This would allow researchers to assess the influence of genetics by comparing the levels of aggression in children with their biological parents who share genetic similarities, as well as their non-biological parents who do not share genetic similarities. By comparing these different groups, researchers can determine the extent to which genetic factors contribute to aggression.Rate this question:

The__________ effect is the result of expectations.
-
Confound
-
Placebo
-
Validity
-
Generalizability
Correct Answer
A. ValidityExplanation
Validity is the extent to which a study accurately measures or predicts what it is intended to measure or predict. In this context, the "expectations" mentioned in the question refer to the validity effect. This effect occurs when participants' expectations or beliefs about a study or treatment influence their responses or outcomes. Therefore, the correct answer is validity.Rate this question:

A distribution has scores of 5, 6, 10, 10, 10, 14, and 40. In this distribution, what two measures of central tendency are the same?
-
Mean and variance
-
Median and mode
-
Median and mean
-
Mean and mode
Correct Answer
A. Median and modeExplanation
In this distribution, the median is 10 because it is the middle value when the scores are arranged in ascending order. The mode is also 10 because it is the most frequently occurring value. Therefore, the measures of central tendency that are the same in this distribution are the median and mode.Rate this question:

Increases in arousal are stimulated by the ______ branch of the nervous system, whereas decreases in arousal are stimulated by the _____ branch of the nervous system.
-
Central, peripheral
-
Sympathetic, parasympathetic
-
Peripheral, central
-
Somatic, autonomic
Correct Answer
A. Sympathetic, parasympatheticExplanation
Increases in arousal are stimulated by the sympathetic branch of the nervous system, whereas decreases in arousal are stimulated by the parasympathetic branch of the nervous system. The sympathetic branch is responsible for the "fight or flight" response, which prepares the body for action and increases arousal. On the other hand, the parasympathetic branch is responsible for the "rest and digest" response, which promotes relaxation and decreases arousal.Rate this question:
