Transcribed Image Text:The image contains a scatter plot depicting the relationship between the percentage of deep talk and well-being scores (z scores). The x-axis represents the well-being scale with z scores ranging from -2.0 to 1.5. The y-axis indicates the percentage of deep talk, ranging from 0 to 100.
Each blue dot on the plot represents an individual, showing their respective well-being score and percentage of deep talk. A green trend line is fitted through the data points, suggesting a positive correlation between well-being and the percentage of deep talk. This implies that individuals with higher well-being scores tend to have a greater percentage of deep talk.
Highlighted in a callout box, one specific dot indicates a person who scored very high on the well-being scale and had a high percentage of deep talk.
