Question

which of the following probability distribution types has a mean, median, and mode that are all equal? constant symmetric positively skewed negatively skewed

Explanation:

In a symmetric probability distribution (e.g., normal distribution), the mean, median, and mode are equal because the distribution is balanced around the center. In skewed distributions (positive/negative skew), mean, median, mode differ (mean pulled toward tail), and "constant" is not a distribution type with equal mean/median/mode.

Answer:

symmetric
