Graph+Drawing

Graph Drawing Before you draw a graph, you need to look at the variables first. There are three kinds of variables to look at. They are: There are some points to take note when plotting a graph:
 * 1) Independent variables - An independent variable is one whose values are chosen by the experimenter. In other words, the values of these variables are independent of the participant's behaviour.
 * 2) Dependent variables - The variable whose value you observe and record in experimental designs is called the dependent variable. In other words, the dependent variable value depends on the behaviour of the participant, rather than being set by the experimenter.
 * 3) Constant variable - Those factors in the experiment that the scientist attempts to keep constant.
 * Give the graph a title, eg:'Graph of distance/m against time/s'
 * Label the axis with name and unit quantity represented by the axis
 * Choose a suitable scale such that the graph is big. The distance from the first point to the last point should be at least half the length/width of the graph paper. Scales based on multiples of three should not be used
 * Mark the values on each axis at regular intervals, say, every 2.0 cm
 * Mark each point on the graph with a small cross. Note that only sharp pencil should be used when plotting a graph

Reflections
In primary school, we were only taught to draw the bar graphs and we were usually only required to shade the graph. However, in secondary school, we were asked to draw the whole graph. I find it a bit challenging as it was my first time drawing a full graph on my own with my own information. I find it difficult understanding where to put the different axis but I find it easy understanding what I should take note when I am drawing a graph. You always hear people say "practice makes perfect", I believe if I practice on my graph, I will soon perfect my skills in drawing graphs.
