Graphs play an essential role in various interpretations and data findings. They are the visual representation of how much progress has been made and what should be next. There are various graphical representation types currently available, such as bar graphs, line graphs, pie diagrams, and pictograms, and each type has dominated in various fields. Line graphs are the most commonly used graphical representations. In logical reasoning for competitive exams, line graphs are used for various data explanations and interpretations. Understanding the concept of a line graph in logical reasoning is essential.
Line Graphs in Logical Reasoning
Line graphs are the graphical representation of data that is never static and depict information that frequently fluctuates over time. A line graph is made by joining the points of the total data. A line graph is also called a line chart. There are four prominent parts of a line graph:
Title: It includes the purpose of the data and how it has been plotted.
X-axis: It elucidates the range that has been taken to divide the data.
Y-axis: It represents the quantity of data that has been taken.
Trend: It refers to the point where the x-axis and y-axis intersect, mostly when the data for both is the same.
Line graphs examine patterns or ranges over time. They also interpret whether a similar pattern would emerge in the future. Line graphs demonstrate the period of consistency or inconsistency between the data. There can be more than a single representation in a line graph. Line graphs also examine the fall or rise of a trend. In logical reasoning, line graphs examine the examinee’s aptitude. As logical reasoning is an essential criterion to mark examinees, it is used in aptitude and competitive examinations. Questions about line graphs assess whether the examinee can interpret the data appropriately. Further, they also reveal if the examinee can understand the rise or fall of a particular event and elucidate its specific cause.
Line graphs test practical knowledge and visual understanding of things and situations. They require a practical understanding to locate the causes, factors, and disturbances in the rise and fall of data. Further, visual understanding is required to locate the point where data changes and examine it in depth.
Uses of Line Graph in Logical Reasoning
Line graphs are a graphical, logical, and practical tool to assess one’s practical and applied competencies. In logical reasoning, line graphs are an essential tool for understanding the various dimensions of data. Here are some uses of line graphs in logical reasoning:
Line graphs help in the understanding of data with practicality. It is a realistic approach to examining the data appropriately. Further, it is essential to draw out the practical solutions in case of any fluctuation in the data.
Line graphs are used to understand the application of practical knowledge. This graphical instrument assesses how much we can apply our practical knowledge. It tests how we connect the present data with the future data.
Line graphs are essential to strategize the next move. It helps in locating how the trend or an event is going on. Based on it, there can be a complete strategy to grow or continue the same trend in future.
Line graphs are useful in determining the overall factor leading to the growth. It helps understand the possible factors leading to the progress of a trend.
Line graphs ensure the logical understanding of an event. It is a practical, logical and chronological pattern to understand a particular situation.
Line graphs help in recording the data logically. They show the data that has been extracted with a systematic and logical methodology.
Line Graph Sample Questions
Line graphs can be better understood for aptitude tests with sample questions. Here are some sample line graph questions for better understanding.
Analyse the following line chart and answer the given questions
What is the total export of the three companies between 1993 and 1996?
What is the average annual export period of Company Z and Company Y? Compare it.
What was the export difference between Company X and Company Y in 1996?
2. The following line graph illustrates the ratio of the company’s imports to exports between 1995 and 2001. Analyse and solve the questions below.
In which the import was propionate to export of the company?
What percentage of increment was seen in the company’s exports between 1995 and 1998?
What is the time when the company’s exports are more than its imports?
What were the total exports of the company in 1998? Illustrate the possible factors.
These are sample line graph questions usually asked in aptitude and competitive examinations.
Conclusion
A line graph is a graphical illustration of the data that continues to fluctuate over time. A line graph is applicable in various fields, such as logical reasoning. It promotes a practical and realistic understanding of a phenomenon or event.
