Explain what it means for two variables to have a negative correlation, using the relationship between stress levels and immune system functioning as a clear example. Describe how changes in one variable correspond to changes in the other in this relationship.
Question: Explain what it means for two variables to have a negative correlation, using the relationship between stress levels and immune system functioning as a clear example. Describe how changes in one variable correspond to changes in the other in this relationship.
Sample answer: A negative correlation means that there is an inverse relationship between two variables, where higher scores on one variable are associated with lower scores on the other. In the context of stress and immune system functioning, this means that as a person's level of stress increases, their immune system functioning tends to decrease. Conversely, as stress levels decrease, immune system functioning tends to increase.
Key points:
- Define a negative correlation as an inverse relationship where higher scores on one variable relate to lower scores on another.
- Identify stress level and immune system functioning as the two variables in the example.
- Explain that as stress levels increase, immune system functioning tends to decrease.
Rubric: To earn full credit, the answer must define a negative correlation as an inverse relationship where one variable increases while the other decreases, identify stress and immune functioning as the two variables, and clearly explain how their values move in opposite directions.

Which of the following best describes the negative correlation between individuals' stress levels and their immune system functioning?
Based on the negative correlation between stress and the immune system, match each variable state or relationship term with its corresponding description or outcome.
Research in health psychology has established a negative correlation between psychological stress and immune system functioning. Based on this relationship, arrange the following participants in order from the person predicted to have the strongest immune system functioning to the person predicted to have the weakest immune system functioning.
If a researcher's analysis of a sample reveals that participants with the lowest recorded levels of psychological stress also consistently exhibit the lowest scores on a measure of immune system functioning, this data pattern would be correctly categorized as a negative correlation.
A student reviewing a health psychology study evaluates the finding that 'lower levels of psychological stress are associated with higher levels of immune system activity' as a positive correlation because both variables are moving toward 'healthier' outcomes. To correctly evaluate the statistical relationship based on the direction of variable movement, the student must identify this as a ________ correlation.
Imagine you are a researcher tasked with creating a simplified dataset to illustrate the negative correlation between psychological stress and the immune system. Which of the following sets of hypothetical participant profiles correctly constructs this inverse relationship?
A researcher conducts a study and finds that as participants' self-reported stress levels increase, their scores on a measure of immune system functioning (such as antibody production) tend to decrease. Which of the following best explains why this relationship is classified as a negative correlation?
A researcher discovers that as individuals' stress levels increase, their immune system functioning scores consistently decrease. If the researcher concludes that this negative correlation provides sufficient evidence to evaluate stress as the direct cause of the decline in immune health, their reasoning is scientifically sound.
A health psychology researcher is studying the negative correlation between stress and immune system functioning. Based on this relationship, rank the following study participants from the one expected to have the HIGHEST immune system functioning (1) to the one expected to have the LOWEST (3).
Analyze the relationship between stress and the immune system by matching each description of the data with the specific concept it illustrates within their negative correlation.
The relationship between stress levels and immune system functioning is an example of a _____ correlation, because as stress increases, immune functioning tends to decrease.
Explain what it means for two variables to have a negative correlation, using the relationship between stress levels and immune system functioning as a clear example. Describe how changes in one variable correspond to changes in the other in this relationship.
Based on Dr. Aris's research design, if her hypothesis is supported, what specific pattern of results should she observe when comparing a student with high stress levels to a student with low stress levels? State what type of correlation this represents and justify your answer using the variables measured.
A researcher reports that in their study, participants who reported the highest levels of stress also exhibited the lowest scores on a measure of immune system functioning, while those with the lowest stress levels exhibited the highest immune functioning. Analyze this finding: does this pattern represent a positive or a negative correlation, and why?
