The first step when reading a graph or chart is to identify the main components and labels. Look at the axes (for bar, line and other simple graphs) or the key (for labelled statistical graphs) to see what each x and y axis stands for. Then consider what the chart is trying to show. Are there any patterns that jump out?
Once you have an understanding of the components of the chart, the second step is to interpret the data. Look for highs and lows, trends or associations, as well as any outliers or gaps in the data that could be significant. Identify the points that illustrate the data most sharply and draw meaningful conclusions from them.
The third step is to draw conclusions about the data and make predictions. Consider the long-term trends or patterns, potential causes and correlations, and if any further research is needed. In some cases, the graph can be used to support arguments or positions.
Overall, reading a graph or chart involves the careful identification of components, followed by careful interpretation and then a deeper understanding of the data to draw appropriate conclusions.
