Correlational Research Evaluate the necessary estimates
Assume you have access to 20 adopted children, all females, and you give each a shyness test.
The test yields scores from 0-20 and the higher the score, the greater the degree of shyness.
You also test the biological mothers and the adoptive mothers. Justify the values of the correlation coefficients that you might expect to see if:
(a) shyness is at least partially inherited (i.e., if shyness is inherited, (1) What would you expect the correlation to be between children and biological mothers on the test?
(2) What would you expect the correlation to be between children and adoptive mothers on the test) and if;
(b) shyness seems to be primarily a function of the environment (i.e., if shyness is due to the environment,
(1) What would you expect the correlation to be between children and biological mothers on the test?
(2) What would you expect the correlation to be between children and adoptive mothers on the test).
You should be presenting two values in your response to Part A and two for Part B (4 correlations in total).
EXAMPLE: If shyness has a biological link, we might expect the correction between the children and their biological mothers to be +0.8, a high correlation, but not a perfect +1:00 correlation (Goodwin & Goodwin, 2017). For the correlation between the adoptive mothers and the children I might expect the correlation to be +0.2.
