Yes, if it is autoregressive.

How would you interpret the findings of a correlation study that reported a linear correlation coefficient of 1.67?
There is not enough information to say much. To start with, the correlation may not be significant. Furthermore, a linear relationship may not be an appropriate model. If you assume that a linear model is appropriate and if you assume that there is evidence to indicate that the correlation is significant (by this time you might as well assume anything you want!) then you could say that the dependent variable increases by 1.67 for every unit change in the independent variable - within the range of the independent variable.
What are the dependent and independent variables for the function y equals 6x plus 8?
The truth is that you can't actually answer, given the information you have. But that's not the answer you are looking for! So, the equation you have is y = 6x+8. There are two variables here, x and y. If you know what x is, you can calculate y as follows: you multiply x by 6 then add 8. So if x is 2, then 6 lots of x is 12, and adding 8 we get 20. So y is 20. The general expression y = mx + c describes a linear relationship between two variables - m is referred to as the gradient and c is called the intercept. This is because if each of the pairs of x and y (e.g. x=2 and y=20 above), the line which join them intercepts (crosses) the y axis at 'c' and has a gradient (steepness) of 'm' (i.e. as you move one unit along the x axis, you go 'm' units up the y axis). So which is dependent and which is independent? Earlier, we calculated y from x. This is the easiest thing to do with this equation. We can say that 'y is dependent on x' or 'x is the independent variable'. Mathematically speaking, though, we could just rearrange the equation (you can see that x = (y-8)/6 by taking 8 away from both sides and dividing both sides by 6). Then it looks like we've switched which one is dependent and independent. But we haven't really - and that is because you are not really asking a maths question, to do with equations, but a science question, to do with causes and effects. In science, we often choose what x's we will use and measure the y's. *This* makes y dependent, but only if we choose it properly - it should actually change as a result of changing the x. So y could be 'reading age' and x could be 'actual age in years'. Most people's reading age increases as they get older (at least up to a certain age). But it is how old they are that is causing their reading age to increase. So we would say that 'actual age in years' is the independent variable and 'reading age' is the dependent variable (because it depends on their actual age). And so if we were doing an investigation into this relationship, it would be conventional to call the 'actual age in years' x and the 'reading age' y. It is normal to call the independent variable 'x' and the dependent variable 'y'. I think that's what you really want to know, but it is important to know why.
What does the vertical axis of a graph show in science?
The vertical is typically the dependent variable (the result of whatever process is causing the event). It could be distance traveled of a projectile, or temperature of a mixed solution, for example.
Could the value of the variable be greater than 12.50?
The unknown value of the variable could be greater, less or even equal to 12.50
Can a variable be divided by a non variable?
This X2/X = X ==========yes X/3 = ?????? ==============No Yes it can. However, dividing by a variable doesn't always work since the variable could evaluate to zero, and you cannot divide by zero. Similar is true if the non-variable is zero.
What are the three types of variables?
The three types of variables are: Independent: it is the one that you manipulate Dependent: the one that reacts to the changes in the independent variable and is measured in a experiment Control: all the other factors that could affect the dependent variable but are kept constant through out an experiment
In a experimentwhat is NOT directly controlled by the Pearson conducting the experiment could it be the dependent variableindependent variablehypothesiscontrol variable?
The independent variable.
What are the independent variable and the dependent variable?
An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.
Is temperature a dependent variable?
yes. the independent variable is what you're testing. it can be a dependent variable depending on the experiment, however it could just as easily be the control if you keep it the same, or the independent if it is the variable you are manipulating rather than measuring. again it all depends on the experiment
What could be a dependent and independent variable for homelessness?
would homelessness be a dependent variable
What is the independent and dependent variable definitions?
The independent variable is the one factor that will be manipulate or changed during the experiment....The dependent variable is the variable that becomes altered as a result of the change that was made in the independent variable...
What is an experiment that involves changing one factor and observing its effect on another while keeping all other factors constant?
Controlled experiment. The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.
How do you use dependent variable in a sentence?
You could say, "Today in our science experiment we had to figure out what the dependent variable was"
Dependent variable used in a sentence?
You could say, "Today in our science experiment we had to figure out what the dependent variable was"
How does the manipulation of an independent variable during a scientific experiment allow a scientist to find a cause-and-effect relationship between variables?
The independent variable, or manipulating variable always affect the outcome of a dependent, or responsive, variable. For example, i have a fire going, and i want to put it out. I could use a range of materials. The range of materials is the independent variable, while the fire going out or not is the dependent variable. This shows a cause and effect.
Is pounds an independent variable?
Pounds is a unit. Amount of pounds sold could be an independent variable (and money made being the dependent variable). On the other hand, amount of pounds sold could be the dependent variable, and time could be the dependent variable. Pounds is just a unit.
How do you control the dependent variable?
Technically you can't control the dependent variable. However, by controlling and monitoring the Independent variable, (the variable which determines the dependent variable) you could lead the dependent variable to produce favourable results.
