Final Answer:
In the study, lower economic class participants demonstrated significantly higher generosity with their points compared to their upper-class counterparts. The results indicated that the n = 12 lower-class participants shared an average of M = 5.2 points with a variance reflected by SS = 11.91, whereas the n = 12 upper-class participants exhibited a comparatively lower average of M = 4.3 points with a variance represented by SS = 9.21.
Step-by-step explanation:
Significantly Higher Generosity in Lower Economic Class:
The central finding of the study highlights a substantial difference in the generosity levels between lower and upper economic class participants. The lower economic class individuals, as evidenced by their higher average points shared, displayed a greater inclination toward generosity in the experimental context.
Lower-Class Participants' Average and Variance:
The specific data for the lower economic class participants indicates that, on average, they shared M = 5.2 points, providing insight into the typical generosity level within this group. The variance, represented by SS = 11.91, signifies the spread or dispersion of individual data points around the mean.
Upper-Class Participants' Average and Variance:
In contrast, upper-class participants exhibited a lower average of M = 4.3 points, suggesting a reduced propensity for generosity compared to their lower-class counterparts. The variance of SS = 9.21 for this group indicates a slightly lower spread of data points around the mean compared to the lower economic class.
Explanation for Each Part:
Significantly Higher Generosity in Lower Economic Class:
The core observation is the noteworthy contrast in generosity levels, indicating that economic class has a discernible impact on individuals' willingness to share points in the study.
Lower-Class Participants' Average and Variance:
The provided averages (M = 5.2) and variance (SS = 11.91) for the lower-class participants serve as quantitative representations of their generosity. The higher average suggests a tendency for increased sharing, while the variance provides information about the spread or variability in their responses.
Upper-Class Participants' Average and Variance:
The lower average (M = 4.3) and variance (SS = 9.21) for the upper-class participants underscore a relatively lower level of generosity. The variance, though slightly less than the lower class, still indicates variability in their responses.
