Final answer:
The statement that members of the same cultural group may be more different from each other than from members of other cultural groups is true about variability among cultural groups, reflecting significant within-group variability.
Step-by-step explanation:
Which of the following is true about variability among cultural groups? A common misconception is that individuals within a cultural group are very similar to each other and that there is more variability between different groups. However, reality shows that there is often more variability within cultural groups than between them. This concept is supported by evidence suggesting that differences within cultures can be profound, as each culture has internal variations and is not a monolithic entity. Factors such as social class, geographical location, language, and personal experiences contribute to this within-group variability. In fact, members of the same cultural group can sometimes be more different from each other than from members of other cultural groups. This concept aligns with the understanding that while there are distinct cultural traditions and practices, individual variations within any given culture are significant. Therefore, the statement D. 'Members of the same cultural group may be more different from each other than from members of other cultural groups' is true about variability among cultural groups.
