How change of origin or scale effect value of co-efficient of co-relation?
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.
How does the impression made by a line graph change when you make the horizontal scale shorter but keep the virtical scale the same?
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
Properties of regression coefficient-statistics?
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.
What is kink in graph?
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.
When is it appropriate to show a break in the scale on a line graph?
When the domain or range of the data are clearly far from the origin, or where the data consist of two separate clusters.
How origin and scale effect arithmetic mean?
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.
How change of origin or scale effect value of co-efficient of co-relation?
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.
What is change of origin and change of scale?
Translation and dilation.
Is Coefficient of correlation is independent of change of origin and scale?
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.
Can 37 represent an even number in some scale?
It can, for example, in base 7 arithmetic.

What is the scale effect economics?
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.
Which is accurate in adding vectors graphical or arithmetic?
graphical is accurate because the vectors added are drawn according to a specified scale.
How many pitches to you need to lower to change a Major Scale to a Minor Scale?
To change a major scale to a natural minor scale, lower the 3rd, 6th, and 7th scale degrees.
What would environmental temperature change effect you?
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.
What is a numbering scale for a vertical axis?
It is zero at the origin, positive above and negative below. Otherwise it can be numbered to any scale.
