Definition

A table chart, alternatively referred to as a data table, presents data in a visual format with organized rows and columns. In this representation, each row usually signifies a data point or record, and each column corresponds to a variable or attribute.

What is Table Chart?

A mathematical line chart is a visual depiction of mathematical functions or equations presented on a two-dimensional plane. Its purpose is to illustrate the correlation between two variables, typically an independent one (such as time, distance, or input) and a dependent one (like temperature, velocity, or output). Employed across diverse disciplines such as mathematics, physics, engineering, economics, and others, mathematical line charts serve as a tool to showcase and examine continuous data trends and mathematical connections.

Types of Table Chart

Various types of table charts are available for representing data, including the following commonly used ones:

• Basic Data Table:
  • Description: A conventional data table structuring information into rows and columns, with each row representing a data point and each column denoting an attribute or variable.
  • Use Cases: Applied for presenting diverse structured data, such as financial reports, survey findings, and data listings.
• Pivot Table:
  • Description: A specialized table enabling users to interactively summarize, aggregate, and manipulate data. Pivot tables often feature capabilities like filtering, grouping, and dynamic calculations.
  • Use Cases: Particularly useful for summarizing and analyzing extensive datasets, especially in business and financial analysis.
• Comparison Table:
  • Description: Tailored for comparing multiple items, like products, services, or options. Rows typically represent items, and columns list attributes or features for comparison.
  • Use Cases: Commonly employed in scenarios involving product comparisons, feature matrices, and decision-making.
• Matrix Table:
  • Description: A table chart structured as a matrix, with rows and columns. Matrix tables are utilized to exhibit relationships between two sets of items, often involving binary (yes/no) or categorical data.
  • Use Cases: Frequently used in survey analysis, contingency tables, and cross-tabulations.
• Time-Series Table:
  • Description: Tailored to display time-series data, where one of the columns represents time intervals (e.g., days, months, years). Time-series tables can encompass metrics, values, or events over time.
  • Use Cases: Suitable for tracking historical data, identifying trends, and monitoring performance metrics over time.

Solved Examples

Example 1: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.

What is the difference between the total number of Technicians added to the Company and the total number of Accountants added to the Company during the years 2016 to 2020?
(a) 128
(b) 112
(c) 96
(d) 88
Ans: (d)
Required difference
= (272 + 240 + 236 + 256 + 288) - (200 + 224 + 248 + 272 + 260)
= 88.

Example 2: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.

What was the total number of Peons working in the Company in the year 2019?
(a) 1312
(b) 1192
(c) 1088  
(d) 968
Ans: (b)
Total number of Peons working in the Company in 2019
= (820 + 184 + 152 + 196 + 224) - (96 + 88 + 80 + 120) = 1192.

Example 3: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.
For which of the following categories the percentage increase in the number of employees working in the Company from 2015 to 2020 was the maximum?
(a) Managers
(b) Technicians
(c) Operators  
(d) Accountants
Ans: (a)
Number of Managers working in the Company:
In 2015 = 760.
In 2020 = (760 + 280 + 179 + 148 + 160 + 193) - (120 + 92 + 88 + 72 + 96)= 1252.
Therefore, the Percentage increase in the number of Managers
(1252 - 760) / 760 * 100 = 64.74%
Number of Technicians working in the Company:
In 2015 = 1200.
In 2020 = (1200 + 272 + 240 + 236 + 256 + 288) - (120 + 128 + 96 + 100 +112) = 1936.
Therefore, the Percentage increase in the number of Technicians
{(1936 - 1200 ) / 1200} * 100 = 61.33%
Number of Operators working in the Company:
In 2015 = 880.
In 2020 = (880 + 256 + 240 + 208 + 192 + 248) - (104 + 120 + 100 + 112 + 144) = 1444.
Therefore, the Percentage increase in the number of Operators
(1444 - 880 / 880 ) * 100 = 64.09%
Number of Accountants working in the Company:
In 2015 = 1160.
In 2020 = (1160 + 200 + 224 + 248 + 272 + 260) - (100 + 104 + 96 + 88 + 92) = 1884.
Therefore, the Percentage increase in the number of Accountants
(1884 - 1160 / 1160 ) * 100 = 62.14%
Number of Peons working in the Company:
In 2015 = 820.
In 2020 = (820 + 184 + 152 + 196 + 224 + 200) - (96 + 88 + 80 + 120 + 104) = 1288.
Therefore, the Percentage increase in the number of Peons
(1288 - 820 / 820 ) * 100 = 57.07%
Clearly, the percentage increase is maximum in the case of Managers.

Example 4: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.

What is the pooled average of the total number of employees of all categories in the year 2017?
(a) 1325
(b) 1195
(c) 1265
(d) 1235
Ans: (b)
Total number of employees of various categories working in the Company in 2017 are:
Managers = (760 + 280 + 179) - (120 + 92) = 1007.
Technicians = (1200 + 272 + 240) - (120 + 128) = 1464.
Operators = (880 + 256 + 240) - (104 + 120) = 1152.
Accountants = (1160 + 200 + 224) - (100 + 104) = 1380.
Peons = (820 + 184 + 152) - (96 + 88) = 972.
Therefore, Pooled average of all the five categories of employees working in the Company in 1997 = 1/5 x (1007 + 1464 + 1152 + 1380 + 972)
= 1/5 x (5975)
= 1195.

Example 5: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.

During the period between 2015 and 2020, the total number of Operators who left the Company is what percent of the total number of Operators who joined the Company?
(a) 19%
(b) 21%
(c) 27%
(d) 29%
Ans: (d)
Total number of Operators who left the Company during 2015 - 2020
= (104 + 120 + 100 + 112 + 144)
= 580.
Total number of Operators who joined the Company during 2015 - 2020
= (880 + 256 + 240 + 208 + 192 + 248
= 2024.
Therefore, Required Percentage
= (580/2024) x 100% = 28.66% ~= 29%.
