one advantage is that you could then see if there were any rises or falls in the type of data that you are collecting e.g. temperature
Which of the following is not a form of presenting data?
With a graph you get an almost instant visual image of the data presented.
The x axis is read first when plotting points in the form (x,y) on the xy-plane.
A graph or chart.
It makes it easier to work out values for x and y for graph plotting purposes.
Chart or graph.
a straight line
A graph can show data in pictorial form - pie or block versions are very common It's actually called a chart. It's not a graph.
To rearrange the electromotive force (emf) equation into a form suitable for plotting a straight graph, you typically isolate the dependent variable on one side. For example, if the equation is of the form ( E = IR + r ) (where ( E ) is emf, ( I ) is current, ( R ) is resistance, and ( r ) is internal resistance), you can rearrange it to ( I = \frac{E - r}{R} ). By plotting current ( I ) on the y-axis and the emf ( E ) on the x-axis, the slope of the resulting line will relate to the internal resistance and the resistance of the circuit.
A bar graph is a collection of data, put in a table- in the form of bars. The graph will have information on the bottom-top, and either side.
To graph an equation that is not in slope-intercept form, you can use the process of finding points on the graph and plotting them. Choose a few x-values, plug them into the equation to find the corresponding y-values, and plot those points on the graph. Then, connect the points with a smooth line to complete the graph.
