Week 7 : Descriptive Statistics

Its is said that the Mean also undergoes same Scaling and Shifting as in DATA
But what if the Data Contains Negative Value (or) the shift is done with negative scale
Will then also the transformation impact be unchanged ?

Any scaling or shifting applied to data, be it negative, float, positive or even zero. Will reflect the same changes to mean as well.

Do we have to consider only the absolute values of any given range ?
while calculating mean

No, not the absolute values. For an intution, refer to the see-saw example from Mitesh Sir’s lecture.
