Wihtin groups, differences in intelligence are highly correlated with _______. Between groups, differences are highly correlated with __________. a. heritability; environment b. environment; genes c. heritability; random error in measurmemt d. genes; the heritability estimate I'm stuck between C and D.. What's the correct answer?
C is wrong i think D
D was wrong on my test.
To determine the correct answer, we need to understand the concepts mentioned in the question: heritability, environment, and genes.
Heritability is a statistical measure that estimates the proportion of variation in a trait or characteristic within a group that is due to genetic factors. It reflects the extent to which differences in a characteristic among individuals within a group can be attributed to genetic variations.
Environment refers to external factors, such as upbringing, education, and social and cultural influences, that can also contribute to individual differences.
Genes, on the other hand, are the units of heredity that are passed down from parents to offspring and determine many traits and characteristics.
Now let's analyze the options given:
a. heritability; environment - This option suggests that within groups, differences in intelligence are highly correlated with heritability (genetic factors) while between groups, differences are highly correlated with the environment. This seems incorrect because heritability refers to genetic factors within a group, not between groups.
b. environment; genes - This option suggests that within groups, differences in intelligence are highly correlated with the environment, while between groups, differences are highly correlated with genes. This is the correct answer because it aligns with the understanding that individual variations within a group are primarily influenced by the environment, while differences between groups are more attributable to genetic factors.
c. heritability; random error in measurement - This option is incorrect because random error in measurement is not related to differences in intelligence within or between groups.
d. genes; the heritability estimate - This option correctly associates genes with differences between groups but incorrectly mentions the heritability estimate, which is a measure used to understand the degree of genetic influence.
Therefore, the correct answer is b. environment; genes. Individual differences within groups are highly correlated with the environment, while differences between groups are highly correlated with genes.
