Graphs

Graphing Scientific Data

Sometimes, we plot scientific data that is recorded in a graph format. The graph is made up of the x and y-axis and at the top of the graph, it is usually the y-axis against the x-axis. We have to scale the graph so that it covers about 3/4 of the page. Scales should not differ by multiples of 3 as well. Each of the graph points has to be marked by an X. We don't connect all of the points but we either draw a best fit line or a best fit curve. We draw the best fit line by drawing the line in the average of the points. If one of the scales has 1 d.p., the rest of the scales must also have 1 d.p.
