Based on the provided example of the Rosenberg Self-Esteem Scale administered on two occasions a week apart, recall what a positive relationship is and how it is visually represented on a scatterplot.
Question: Based on the provided example of the Rosenberg Self-Esteem Scale administered on two occasions a week apart, recall what a positive relationship is and how it is visually represented on a scatterplot.
Sample answer: A positive relationship is one where the variables change in the same direction, meaning higher scores on the first administration are associated with higher scores on the second administration. On a scatterplot, this relationship is visually represented by data points that progress from the lower left to the upper right.
Key points:
- A positive relationship means variables change in the same direction.
- Higher scores on the first occasion are associated with higher scores on the second.
- Data points on a scatterplot progress from the lower left to the upper right.
Rubric: To receive full credit, the answer must recall that a positive relationship involves variables changing in the same direction, note the specific association of higher scores on the first test with higher scores on the second test, and describe the scatterplot's visual representation as progressing from the lower left to the upper right.

When students' scores on a self-esteem measure are plotted on a scatterplot for two administrations one week apart, a positive relationship is indicated by data points that progress from the lower left to the upper right of the graph.
A researcher is analyzing Rosenberg Self-Esteem Scale scores collected from the same students on two different occasions. If the data demonstrate a positive relationship, which of the following best describes the expected pattern of the results?
A researcher is evaluating the test-retest reliability of the Rosenberg Self-Esteem Scale and observes a strong positive relationship between scores across two weeks. Match each participant's Week 1 score with the Week 2 score that most likely illustrates this positive correlation.
A researcher is examining scores from the Rosenberg Self-Esteem Scale collected from students on two occasions, one week apart. Arrange the following steps in the logical order required to analyze whether the variables change in the same direction, creating a specific pattern on a scatterplot.
Based on the example of students taking the Rosenberg Self-Esteem Scale on two occasions, which of the following associations indicates a positive relationship between the scores?
A researcher is plotting scores from two administrations of the Rosenberg Self-Esteem Scale taken one week apart. Match each feature of the resulting positive relationship with its corresponding graphical or conceptual description.
A researcher is evaluating the stability of scores on the Rosenberg Self-Esteem Scale across two testing sessions. After appraising a scatterplot where the data points move from the lower left to the upper right, the researcher concludes that high scores on the first test are paired with high scores on the second. This evaluative determination that the variables move in the same direction classifies the association as a(n) _____ relationship.
A researcher administers the Rosenberg Self-Esteem Scale to 30 college students at the start of a semester and again eight days later. When the scores are plotted on a scatterplot, the data points run from the upper left to the lower right of the graph. Applying the principle illustrated by the Rosenberg Self-Esteem Scale example, the researcher is correct to conclude that this pattern demonstrates a positive relationship between the two sets of scores.
In the Rosenberg Self-Esteem Scale example, a researcher breaks down why the scatterplot pattern qualifies as a positive relationship. The key analytical insight is that the two variables change in the _____ direction: students who scored higher on the first administration also tended to score higher on the second administration.
A researcher has collected Rosenberg Self-Esteem Scale scores from students on two occasions one week apart and wants to evaluate whether a positive relationship exists and what it means for the scale's usefulness. Arrange the following steps in the most logical evaluative order.
Based on the provided example of the Rosenberg Self-Esteem Scale administered on two occasions a week apart, recall what a positive relationship is and how it is visually represented on a scatterplot.
Diagnose the type of relationship demonstrated by these scores and explain the visual pattern this relationship will produce on a scatterplot. Justify how this pattern demonstrates the direction of variable change.
Suppose you are plotting data from a study where students took the Rosenberg Self-Esteem Scale twice, a week apart. If the results show a positive correlation, apply this concept to predict the specific layout pattern of the data points on your scatterplot and describe the direction of change in the variables.
