Tips and Tricks: Table Charts | Quantitative Aptitude for SSC CGL PDF Download

Definition 

Table charts serve as a foundational instrument for efficiently arranging and displaying data. Whether you're a student gearing up for exams, a professional scrutinizing business data, or an individual seeking to enhance data presentation proficiency, this resource provides valuable insights and techniques to optimize the utilization of table charts.

Tips and Tricks for Table Charts solution

The following guidelines aid in resolving table chart challenges:

• Concise Descriptions: Avoid detailing every piece of presented data; focus on highlighting the key points for each feature while ensuring coverage of all features.
• Identify Significance: Pay attention to noteworthy data points, such as the highest or lowest values.
• Grouping Data: Attempt to categorize data into groups. This may involve applying general knowledge about the world, like distinguishing between developed and developing countries.

Note: Before creating a table chart, consider whether a table is the best format for your data. Tables excel at presenting structured, detailed information. If you need to showcase trends or comparisons, you may want to explore other chart types like bar charts, line charts, or pie charts.

Step by Step guide to solve Table chart

• Comprehend the Table Structure: Start by closely analyzing the arrangement of the table, identifying column headers, row labels, and any subcategories or divisions.
• Review Questions in Advance: Before delving into the table, review the associated questions. This preliminary step will guide your attention and assist in pinpointing the specific information needed for extraction or analysis.
• Quick Overview of the Table: Initiate with a brief scan of the entire table to grasp a general understanding of its contents. Take note of any noticeable patterns, trends, or anomalies that stand out during this initial examination.
• Identify Pertinent Rows and Columns: After reviewing the questions, highlight the rows and columns in the table directly linked to the information necessary for addressing those questions.
• Emphasize Key Values: Direct your focus to the essential values, numbers, or data points directly relevant to the questions. Avoid getting entangled in irrelevant details.
• Utilize Filtering and Sorting: In the case of an extensive table, consider employing filters or sorting options (if available) to streamline the data or arrange it in a manner conducive to your analysis.
• Perform Calculations and Summaries: If the questions entail calculations or summarizations (e.g., averages, totals, percentages), systematically carry out these operations. Verify your calculations to ensure precision.

Examples

Example 1:

How many marks did Yash get in all Subject together?
(a) 456
(b) 477
(c) 487
(d) 507
Ans: (b)

= 109.5 + 120 + 105 + 45 + 48.75 + 48.75
= 477

Example 2:

What is the average marks obtain by all the student in Chemistry?
(a) 55.67
(b) 48.25
(c) 56.65
(d) 64.33
Ans: (c)
Total number scored by 3 students in Chem = 193.

Example 3: Classification of 100 Students Based on the Marks Obtained by them in Physics and Chemistry in an Examination.

If at least 70% marks in Physics are required for pursuing higher studies in Physics, how many students will be eligible to pursue higher studies in Physics?
(a) 27
(b) 32
(c) 34
(d) 41
Ans: (b)

= No. of students scoring 35 and above marks in Physics
= 32

Example 4: Classification of 100 Students Based on the Marks Obtained by them in Physics and Chemistry in an Examination.
If it is known that at least 25 students were eligible for a Symposium on Chemistry, then the minimum qualifying marks in Chemistry for eligibility to Symposium would lie in the range?
(a) 40-45
(b) 30-40
(c) 20-30
(d)  Below 20
Ans: (c)
Since 66 students get 20 and above marks in Chemistry and out of these 21 students get 30 and above marks, therefore to select top 25 students in Chemistry, the qualifying marks should lie in the range 20-30.
