The shape of a distribution plays a significant role in determining the appropriate measure of center. Here’s a breakdown:
1. **Symmetrical Data**: When a distribution is symmetrical (like a normal distribution), the mean is typically the best measure of center. This is because the mean provides a good representation of the data since values are evenly distributed around the center.
2. **Skewed Data**: When a distribution is skewed (either positively or negatively), the mean can be heavily influenced by extreme values (outliers). In such cases, the median is often a better measure of center because it is not affected by outliers and represents the middle value more accurately.
Given these considerations, the appropriate answer from your options is:
**Symmetrical data means that the mean is the best measure of center.**
This succinctly captures the relationship between the shape of the distribution and the choice of measure of center.
