A data set has a mean of 14.5 and a median of 11.2. Which of the following terms would describe this data set?

A bimodal distribution is characterized by having two modes, or peaks, in its frequency distribution. The information provided only mentions the mean and median, which do not indicate the presence of multiple peaks. Therefore, without further data showing two distinct modes, this choice does not accurately describe the data set.

A left-skewed distribution occurs when the mean is less than the median, indicating that there are outliers or a tail on the lower end of the data. Since the mean (14.5) is greater than the median (11.2) in this data set, it cannot be described as skewed left.

A symmetrical distribution has equal mean and median values, indicating a balanced spread of data around a central point. In this case, the mean and median are not equal (mean = 14.5 and median = 11.2), thus the data set cannot be categorized as symmetrical.
