The geometric mean is sensitive to changes in scale and origin. When the scale of the data changes (e.g., multiplying all values by a constant), the geometric mean is also multiplied by that constant, reflecting the change in scale. However, changing the origin (e.g., adding or subtracting a constant from all values) does not affect the geometric mean, as it relies on the multiplicative relationships between values rather than their absolute positions. Thus, only changes in scale impact the geometric mean, while changes in origin have no effect.
Translation and dilation.
If you change the scale factor of a geometric figure by a factor "x", that is, keeping the new figure similar to the old one, the perimeter (which is also a linear measurement) will change by the SAME factor "x".Note that any area will change by a factor of x squared.

The scale factor in dilation determines the degree of enlargement or reduction of a geometric figure. A scale factor greater than 1 enlarges the figure, while a scale factor between 0 and 1 reduces it. The shape of the figure remains the same, but the dimensions change proportionally based on the scale factor. For example, a scale factor of 2 doubles the size of each dimension, while a scale factor of 0.5 halves them.
No, the geometric mean is not typically used to determine the scale of an object. It is primarily used in statistics to calculate the average of a set of numbers, particularly when those numbers are multiplicative or vary exponentially. Scale is usually determined through measurements or ratios rather than statistical means.
The mean and scale will change by the factor of change for the sample data.
The correlation coefficient is unaffected by change of origin or scale unless one of the sets of variables is multiplied by a negative term, in which case the correlation coefficient will become negative.

Suppose a set of observations for a variable X has a mean mx.If a scale factor of a is applied to the observations, and the origin is shifted to the left by a distance b, then the new mean will be (m/a)*x + b.
No, it is not.
The Coeffecient of corelation is definitely independent of origina and scale. If r(x,y)= cof or cor b/w X and Y let W=aX+b and Z=cY+d then r(x,y)=r( W,Z) Note that adding or subtracting a constant in all values of a random variable changes its scale. While multiplication or division change scale. The Form W=aX+b, caters the change both in origin and scale.

Wikipedia defines geometric shape as follows:A geometric shape is the geometric information which remains when location, scale, orientation and reflection are removed from the description of a geometric object.The above definition does not address the fact that non-mathematical attributes, such as colour, taste, smell, temperature, and so on can also be removed.
