How do you construct a line graph?

Steps of construction of line graph: On a graph, draw two lines perpendicular to each other intersecting at O. The horizontal line is x-axis and vertical line is y-axis. Mark points at equal intervals along x-axis and write the names of the data items whose values are to be marked.

Why do we construct graphs?

Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. If the data shows pronounced trends or reveals relations between variables, a graph should be used.

How do you interpret a graph?

To interpret a graph or chart, read the title, look at the key, read the labels. Then study the graph to understand what it shows. Read the title of the graph or chart. The title tells what information is being displayed.

What are the advantages of line graphs?

Line graphs can give a quick analysis of data. You’re able to quickly tell the range, minimum/maximum, as well as if there are any gaps or clusters. This also means that it can easily observe changes over a certain period of time. When drawing them, you’re able to use exact values from your data.
