Which type of distribution indicates that scores are concentrated around two values rather than spreading evenly across a range?

A bimodal distribution is characterized by having two distinct peaks or modes in its frequency distribution, which indicates that data points are concentrated around two different values. This concentration around two values signifies that there may be two underlying processes or groups influencing the data, leading to the observed dual peaks.

In contrast, a skewed distribution has a tail that extends more towards one end rather than having two concentrated peaks. A uniform distribution features scores that are evenly spread across the range, lacking any concentration around specific values. A normal distribution is symmetrical with a single peak representing the mean, indicating a concentration of scores around a single central value rather than two. Thus, the defining feature of a bimodal distribution is its characteristic of having scores concentrated around two specific values, making it the correct choice in this case.
