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.
Best Answer:The impression made by aline graph change when you make the horizontal scale shorter but keep the vertical scale is that the new line will be much steeper than the original!!Votes:12
8.7.4 Properties of Regression Coefficients:(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity.(c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, providedr > 0.(d) Regression coefficients are independent of the changes of origin but not of scale.
When the domain or range of the data are clearly far from the origin, or where the data consist of two separate clusters.
It is a zig-zag sign near the origin that shows that the scale interval started there, just that the numbers after it were skipped. It's like a shortcut.
Oh, dude, like, when you're talking about the origin and scale in arithmetic mean, you're basically just messing with the values of the data points. The origin is where your data starts, and the scale is how much you're stretching or squeezing those values. So, if you change the origin or scale, it's gonna totally mess with your arithmetic mean because you're basically playing around with the numbers. But hey, it's all good, just plug those numbers into the formula and you'll be fine.

Translation and dilation.
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.
It can, for example, in base 7 arithmetic.

effect of cash management on small scale industries
The scale effect indicates what happens to the demand for the firm's inputs as the firm expands production. As long as capital and labor are "normal inputs," the scale effect increases both the firm's employment and capital stock.
graphical is accurate because the vectors added are drawn according to a specified scale.
To change a major scale to a natural minor scale, lower the 3rd, 6th, and 7th scale degrees.
Environmental temperature change would effect everything from crop growth to hibernation. It would effect me as a homo sapien greatly as all of my crops would be dying - leaving me to starve - and the temperatures that I have adapted to would no longer be the ones I would be subjected to. This could potentially be lethal. Of course, the effects of environmental temperature change would vary depending on the scale of the change.
It is zero at the origin, positive above and negative below. Otherwise it can be numbered to any scale.
