Drawing Graphs and Conclusions
Two of the most important skills in science are being able to graph experimental data and draw
conclusions from that data. To help you improve on these skills, the independent variable is always
plotted on the horizontal (x) axis while the dependent variable is always plotted on the vertical (y)
axis. Remember to label the axes of your graph including units and to give your graph a title.
Question 1: Using the results in the table below, draw an appropriate graph of the data.
Mass of water (kg)

0.7
0.9
1.2
1.6
2.2
Temperature change (°C)

Question 2: What is the relationship between the mass of water and the resulting temperature
change?
Question 3: Are there any anomalous results? If so, what result would you expect instead?
Sometimes graphs can contain different sets of data that need to be compared. They are however
a little bit harder to create. Challenge yourself and see if you can graph the following data.
Question 3: Graph the data in the table below.
