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 else can I help you with?
What name is given to a statistical graph that plots three or more related quantities simultaneously?
A multivariate graph.
Differentiate the three types of variable?
differentiate the three types of variables from one another
Is a scatter plot the same as a line graph?
A scatter plot is a plot of paired (x,y) data with a horizontal x axis and a vertical y-axis. (definition as given in Elementary Statistics by Triola). Textbooks may have different definitions. If one variable is considered an independent variable, then generally it is the x value. This is particularly important if there is a relationship between the two variables, in that knowing the x value helps predict the y value. A best fit line can be drawn through the points. A line graph in general connects points on a graph. The x-axis may not be a numerical value or it may not be equal spaced increments. For example, suppose I did surveys in years 2001, 2002 and 2009, counting how many accidents there were in a particular intersection. A line graph would show three years, 2001, 2002 and 2009, as equal spaced intervals on the x-axis. The above definition is consistent with plots made in Excel. I note that some textbooks may consider a line graph as any plot that contains lines connecting the data. See related links. You can find many good examples of graphical displays of data on the internet.
How many types of correlation?
There are 3 types1.positive/ negative/zero/2.linear/non-linear3.simple/multiple/partial- If the direction is same,the relationship is positive-If the direction is opposite , the relationship is negative-If the amount of change is constant in different variable it is linear-If the amount of change is not constant in different variable is non- linear-If it is establishing a relationship between two characteristic then it is simple- If it is establishing a relationship between three or more characteristic then it is multiple-If it is establishing a relationship between only one of all the variable then it is partial
What are the three parts to a hypothesis?
The three parts of a hypothesis are to identify the problem, make an educated guess and identify the major variables. A hypothesis is the description of a scientific question.
What are the three conditions necessary for causation between variables?
The three conditions necessary for causation between variables are covariance (relationship between variables), temporal precedence (the cause must precede the effect in time), and elimination of plausible alternative explanations (other possible causes are ruled out).
Does ten and three fourths show direct variation?
No. Direct variation describes a relationship between two variables. It has nothing to do with the value of a single number.
What is a three dimensional graph?
A three-dimensional graph is a visual representation of data that displays three variables along three axes: typically labeled X, Y, and Z. This allows for the depiction of complex relationships and interactions between the variables in a three-dimensional space. In such graphs, points are plotted based on their coordinates in this space, enabling the analysis of trends, patterns, and correlations that may not be evident in two-dimensional graphs. Common examples include scatter plots, surface plots, and 3D bar charts.
What is phase change of water graph?
The phase change of water graph shows the relationship between temperature and state of water. It includes the three main phases of water: solid (ice), liquid (water), and gas (steam). The graph illustrates how water transitions between these phases with changes in temperature and pressure.
What are the three different types of correlation?
The three different types of correlation are positive correlation (both variables move in the same direction), negative correlation (variables move in opposite directions), and no correlation (variables show no relationship).
What is an alignment diagram?
An alignment diagram is another name for a nomogram, a mathematical diagram in which the relationship between three variables is represented by a straight line or curve for each variable.
What is an alignment chart?
An alignment chart is another name for a nomogram, a mathematical diagram in which the relationship between three variables is represented by a straight line or curve for each variable.
What are the 3 basic research methods of psychology?
The three basic research methods in psychology are experimental research (manipulating variables to determine cause and effect), correlational research (examining the relationship between variables without manipulation), and descriptive research (observing and recording behaviors without manipulating variables).
Can you graph an equation with four variables?
Graphing an equation with four variables directly in a traditional three-dimensional space is not possible since we can only visualize three dimensions at a time. However, one can represent four-variable equations using various techniques, such as fixing one or more variables at specific values and then graphing the resulting three-dimensional surface. Alternatively, data visualization techniques like hypercubes or projections can help illustrate relationships between four variables in a more abstract way.
Why is there no relevant graph for the combined gas law?
The combined gas law states that P1V1/T1 = P2V2/T2. Note there are three variable, namely P(pressure), V(volume) and T(temperature). Thus, there can be no single relevant graph. One could have a graph of P vs. V or P vs T for example, but not a graph including all three variables.
What is a graph with 3 axis called?
It could either be a graph with 3 horizontal axes; or a graph with one horizontal axis and two vertical ones. This would be for situations where you wish to plot several dependent variables against the same independent one, but the units or scale of the independent variables do not allow you to use the same axis. For example, you may wish to plot the rate of inflation (%) and numbers unemployed (millions) in an economy against the same independent variable, time; or it could be a three dimensional graph. And, by that is meant a genuine 3-d graph with 3 interacting variables rather than a graph that has been given a spurious (and sometimes misleading) third dimension.
What is the relationship between the three countries of NAFTA?
The relationship between the three signatories of the North American Free Trade Agreement is commercial; they are trading partners.
