A research team wants to examine how daily screen time relates to self-reported happiness levels in a sample of adults without manipulating either variable. Apply the descriptive statistical methods discussed in the text to determine which method is most appropriate for this research goal, and justify your choice.
Question: A research team wants to examine how daily screen time relates to self-reported happiness levels in a sample of adults without manipulating either variable. Apply the descriptive statistical methods discussed in the text to determine which method is most appropriate for this research goal, and justify your choice.
Sample answer: The research team should compute a correlation coefficient. This method is appropriate because their goal is to assess the statistical relationship between two naturally occurring variables (screen time and happiness levels) rather than describing the percentage of people engaging in a single behavior.
Key points:
- Identify the correlation coefficient as the correct method to apply.
- Justify the choice by stating the goal is to assess the statistical relationship between two variables.
- Apply the concept that screen time and happiness are naturally occurring variables in this non-experimental design.
Rubric: The answer should correctly identify the correlation coefficient and justify its application by explaining that the study involves assessing the relationship between two naturally occurring variables.

In non-experimental research, which of the following is commonly computed to assess the statistical relationship between two naturally occurring variables?
A social psychologist is conducting a non-experimental study to determine the strength and direction of the relationship between the number of friends a person has and their self-reported loneliness. To describe the statistical relationship between these two naturally occurring variables, the most appropriate descriptive statistic to compute is a percentage.
A researcher finds that a specific percentage of students report feeling 'stressed' during finals. To move beyond describing this proportion and analyze how 'stress levels' vary in conjunction with 'hours of sleep,' the researcher computes a correlation coefficient. This statistical shift allows the researcher to evaluate the ______ between these two naturally occurring variables.
A researcher is evaluating the best way to describe the data from a non-experimental study on the link between 'daily stress levels' and 'quality of sleep.' Order the following descriptive methods based on how effectively they assess the statistical relationship between these naturally occurring variables, from the least comprehensive to the most common and robust method.
In non-experimental research, simple percentages are commonly used to describe the proportion of individuals in a sample who engage in a specific behavior or hold a particular belief.
While both are used as descriptive statistics in non-experimental research, what is the specific goal of computing a correlation coefficient as opposed to a simple percentage?
In non-experimental psychology research, different descriptive statistics serve different descriptive goals. Match each statistic to the specific task it is designed to perform.
A researcher is designing a non-experimental study. Match each research goal to the descriptive statistic that best addresses it.
A health psychologist surveys 200 adults and first reports that 45% of them sleep fewer than seven hours per night. She then shifts her focus: she wants to analyze whether adults who consume more caffeine per day also tend to sleep fewer hours. Because this second research goal involves examining the direction and strength of a statistical relationship between two naturally occurring variables in a non-experimental design, she should compute a _____.
A research team is evaluating how to select and apply the most appropriate descriptive statistic for a non-experimental study on the link between daily social media use and academic self-efficacy. Order the following decision steps from first to last.
In non-experimental research, descriptive statistics can be used in two primary ways as described in the text. Identify these two ways and recall what each is designed to describe or assess.
Based on the text, explain the conceptual difference between the psychologist computing simple percentages versus computing a correlation coefficient for her study variables. What different insights about her sample will she comprehend from each method?
