What is a statistical measure that shows how pairs of variables are related?
Peppysbiggestfan
it means that there are two numbers that are not constant. the value of each number is always related to the other based on an internal function/formual. those two vairables are usually related through a 3rd constant
For example, look at surface of a rectangle that is 100 square meters.
its length might be 10, and its width ten
or its length might be 20, and its width 5
the length and width are vairables (changing), but they are related in a way that they always produce the same constant (surface).

Does a line graph show the relationship between three variables?
a simple 2d xy line graph has only the possibility for 2 different variables (x and y). for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs.
What is plotted on the x axis of a line graph?
The independent variable - if there is one. A variable that is common to a number of pairs of variables that you wish to compare. For example, if you want to compare height and mass at various ages, the age would be on the x-axis.
What is sample regression function?
To take a simple case, let's suppose you have a set of pairs (x1, y1), (x2, y2), ... (xn, yn). You have obtained these by choosing the x values and then observing the corresponding y values experimentally. This set of pairs would be called a sample.For whatever reason, you assume that the y's and related to the x's by some function f(.), whose parameters are, say, a1, a2, ... . In far the most frequent case, the y's will be assumed to be a simple linear function of the x's: y = f(x) = a + bx.Since you have observed the y's experimentally they will almost always be subject to some error. Therefore, you apply some statistical method for obtaining an estimate of f(.) using the sample of pairs that you have.This estimate can be called the sample regression function. (The theoretical or 'true' function f(.) would simply be called the regression function, because it does not depend on the sample.)
What is the correlation coefficient symbol?
The answer is r.Actually 'r' is the usual symbol for the correlation coefficient statistic calculated for a sampleof paired values. The correlation coefficient for a population of pairs of random variables distributed according to a binomial normal distribution is usually denoted by the Greek letter 'rho'.
The following pairs of variables are all strongly correlated positively or negatively as indicated but for only some of them is there a cause-and-effect relationship between the variables Which o?

What are forces in pairs called?
to measure forces what do you use?
What pairs of variables is negatively correlated?
The number of times a pencil is sharpened and its length
How do you determine the relationship is non-proportional when given a table?
The ratio of the two variables is not the same for all pairs.
How is the list of the factor pairs for 588 related to the rectangles that can be made for the factor pairs?
One to one.
What is the related pairs of 1 million?

What is related pairs?
I'd hate to give you a definition like, "Related pairs of numbers are pairs of numbers that are related" so let's just go with an example. Let the first number of a pair represent a quantity of bicycles. Let the second number represent the number of tires per bicycle. With 1 bicycle you would have 2 tires, with 2 you would have 4 and so on. (1,2)(2,4)(3,6)(4,8) are related pairs of numbers.

Which statistical test do you use if you need a correlation for many pairs such as if you have data on 50 couples and want to know if they are similar or different based on a range of values?
student's t test
Which appendages in the cephalic reigon are related to the eating of food?
Cephalic refers to the head. The appendages related to eating include the mandibles and two pairs of maxillae. There are also three pairs of maxillipeds that move food towards the mouth.
