Question

20. It appears that there is a significant relationship between cognitive ability and social status, at least for birds. Boogert, Reader, and Laland (2006) measured social status and individual learning ability for a group of starlings. The following data represent results similar to those obtained in the study. Because social status is an ordinal variable consisting of five ordered categories, the Spearman correlation is appropriate for these data. Convert the social status categories and the learning scores to ranks, and compute the Spearman correlation. Subject Social Learning Status Score 10 19 17 17 12

Explanation / Answer

Correlation: Social status, Learning Score

Pearson correlation of Social status and Learning Score = 0.952

Spearman Rho: Social status, Learning Score

Spearman rho for Social status and Learning Score = 0.960

So,there is a almost linear positive correlation between social status and Learning Score.
