Which graph is a cumulative frequency graph?
For ungrouped data, the graph for a random variable (rv), X, is usually a line graph whose horizontal axis is the values that the random variable can take, and whose vertical axis is the number of observations (or outcomes) of the random variable that are less than or equal to that value of the rv. For grouped data the graph is usually a corresponding bar graph.
On a line graph the ratio of the change in the y variable to the corresponding change in the x variable is called a lines what?
The rise and the run.
When constructing a graph using breathing rates to temperature what are their variables in a graph?
The independent variable is the temperature. The dependent variable will be some measure of breathing rate - probably number if inspirations per minute.
What graph graph indicates that there is a linear relationship between the dependent variable and the independent variable?
a graph of the independent variable and dependant that shows a graph with a fixed gradient (I.E a line graph) The equation of the graph will be given by y = mx +c where m is the gradient and c is a constant
What is cyclomatic number of a graph is called?
cyclomatic number of a graph is e.n+1 where e is number of edge of graph and n is number of node in graoh g
What is the Y axis called line graph?
It is called the dependent variable

What is the graph of inequality in one variable?
It is a section or several sections of the number line.
What is the line called on a line graph that is the ratio of the change in the y-variable to the corresponding change in the x-variable?
The rise and the run.
On a line graph the ratio of the change in the y variable to the corresponding change in the x variable is called a lines what?
The rise and the run.
Where On a line graph where is the dependent variable placed?
On a line graph, where is the dependent variable placed?

The variable plottted on the horizontal x-axis is called?
You're generally going to put the independent variable on the horizontal axis, ie the variable that you decided to change in the experiment. If it is a continuous variable (ie a run of numbers) then you will be plotting a line graph and joining with a line or curve of best fit. If your variable is categoric ie has labels rather than numbers, or if it is whole-number only, then you're going to be plotting a bar graph.
Say someone used a line graph to show info about the number of CDs she owned by different arists.Is a line graph a good choiceto show data.... Why or why not?
A line graph is not a good way to represent the data as the number of CDs is a continuous variable, but the artists are a discrete, categoric variable. A line graph should be used when both variables are continuous. A bar chart or bar graph should be used when one variable is continuous and one is discrete.
Where does the dependent variable always go on the graph?
dependent variable always go on y.axis on the graph.
What graph graph indicates that there is a linear relationship between the dependent variable and the independent variable?
a graph of the independent variable and dependant that shows a graph with a fixed gradient (I.E a line graph) The equation of the graph will be given by y = mx +c where m is the gradient and c is a constant
Which component in a graph indicated an independent factor?
The x-axis of a graph is always your independent variable and the y-axis is the dependent variable. The independent variable is so called because it can stand alone as data and does not depend on other information to make sense.
