MAKE AND INTERPRETET A LINE GRAPH


Line graphs provide a visual representation of the relationship between variables and how that relationship changes. For example, you might make a line graph to show how an animal's growth rate varies over time, or how a city's average high temperature varies from month to month. You can also graph more than one data set on the same line graph, as long as it relates the same two variables. So how do you make a line graph? Just follow these steps to find out.

 

 

1. Draw two large lines in your paper: those represent the two axes: one vertical and one horizontal. The vertical axis is designated the Y-axis and the horizontal as the X-axis. The place where the lines cross is called the origin.

 

2. Label each axis with the variable it represents: to continue the proposed task, you would label the x-axis as "years of the football league" from 1980 to the current year and the y-axis as "the number of goals scored by your team" from 1 to 120.
 

 

3. Decide how many units every line on the graph represents for each of your variables: you might designate a scale per line to measure time in years along the Y-axis, and a scale per line to measure "numbers of goals" along the X-axis. Be careful with that: if the range isn't very high, you can have a larger scale, spreading it out more so that it fills up the graph instead of just covering 10% of it. Be careful with that!
 
4. Label several of the lines along each axis with the unit of measurements o the right (horizontal axis) and on the top (vertical axis).
 
5. Plot your data on the graph. For example: If your team scored 30 goals in 1990, locate this number and this year on the X-axis and Y-axis. Trace both lines to the point where they intersect. Place a dot on the intersection. Repeat for all of your other data until you've plotted each point on the graph.
 
6. Connect the left-most dot and the dot to its right with a straight line. Continue connecting the dots, one by one, working from left to right. Make sure that it looks like you're connecting the points with straight lines only, so that the graph does not look curved. Once you've connected all of the points, you will have successfully graphed all of the data.
 
7. Study the peaks (ups) and valleys (downs) in the line. Use what you already know about the topic to explain the causes and consequences of the ups and downs.
