The question presents a scenario where you computed a numerical summary (the average salary) from a subset of a larger group. 
Option 1: Parameter. A parameter would describe a numerical summary of the entire population (for example, the true mean salary of all 1000 Masters students). Since the calculation used only 100 MBA students, not the whole population, this is not a parameter. 
Option 2: Median. The median is the middle value that separates the higher half from the lower half in a data set. The value given is the average (mean), not the median, so this option mislabels the summary. 
Option 3: Statistic. A statistic is a numerical summary computed from a sample, such as the sample mean you calculated from 100 MBA students. This aligns with the described process and data scope. 
Option 4: Mode. The mode is the most frequently occurring value in a data set. Salary data typically do not have a single most frequent value, and the reported figure is not identifying a mode, so this choice is incorrect.
