Expert Answer:

begin mathsize 16px style The space answer space is space MODE space equals space 3 space MEDIAN space minus space 2 space MEAN
This space relation space is space called space the space empirical space formula.
This space formula space is space depend space upon space the space skewness space of space the space distribution.
Skewness space is space the space asymetrical space curve.
We space have space positive space as space well space as space negative space skewness.
For space positive space skewness space Mean greater than Median greater than Mode
And space for space negative space skewness space Mean less than Median less than Mode.
Based space on space this space formula space is space derived.
This space you space will space learn space in space your space higher space studies. end style
