Make up a set of at least 12 numbers that has the following landmarks:
Minimum: 50
Maximum: 57
Median: 54
Mode: 56

The lowest number would be 50 and the highest is 57. That takes care of two scores. Since the mode is the most frequently occurring score, at least two scores will be 56. Still 8 scores remain.
Insert the remaining scores so half will ≤ median and half ≥ median, since the median = 50th percentile. You may have to add scores to the modal value.
