Question

How can graphs be used in real life ?

Answer 1

Hint: In the question, we are asked to write how graphs can be used in our everyday life. First, understand the meaning of graphs and know how the variables are plotted in a graph. Then check for the uses of graphs in different fields like science, medicine, statistics, business etc.

Complete step by step solution:
We are asked to write about the uses of graphs in real life.First let us understand what graphs are. Graphs can be defined as diagrams which show the relationship between two quantities or variables and each of the quantity or variable is measured along one the axes. There are two axes, x-axis and y-axis which are perpendicular to each other, on each axis each variable is measured.Some uses of graphs in real life are,

1. Graphs are used in projects and business for comparison between two quantities and observing how each quantity changes with respect to the change in the other.
2. Graphs are used in medical science or healthcare to estimate the strength of medicine.
3. Graphs are used for statistical purposes for data which can only be explained with the help of graphs.
4. Graphs are used in research purposes where data collected are quantitative, tables or charts and need a visual image to analyse the results.
5. Graphs can be used for planning monthly budgets as through graphs it is easy to know the mistakes and improvements which can be made.

Note: In the above question we have discussed the uses of graphs. There are six types of graphs which are line graph, bar graph, histogram, pictograph, area graph and scatter plot. The common and simplest graph is line graphs which are used in every field.
