An unknown number is a variable and its symbol is usually in the form of a letter such as x or y
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.
The rise and the run.
The independent variable is the temperature. The dependent variable will be some measure of breathing rate - probably number if inspirations per minute.
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
The independent variable on a bar graph is the variable that is manipulated or categorized to observe its effect on the dependent variable. It is typically represented on the x-axis (horizontal axis) of the graph. For example, in a bar graph showing the sales of different products, the product categories would be the independent variable.
It is called the dependent variable
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.
It is a section or several sections of the number line.

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.
On a line graph, where is the dependent variable placed?
The independent variable is the temperature. The dependent variable will be some measure of breathing rate - probably number if inspirations per minute.
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.
dependent variable always go on y.axis on the graph.
The y-axis is the vertical line on a line graph.
