Formulas for Table Chart
Table charts become even more powerful when you incorporate mathematical formulas. Here are several ways to use formulas effectively within table charts:
- Basic Arithmetic Operations:
- Summation: Use the SUM formula to calculate the total of a column or row by adding up the values in individual cells.
- Averages: Compute the average of a set of values within a column or row using the AVERAGE formula.
- Subtraction and Multiplication: Perform subtraction and multiplication operations as needed to derive new values based on existing data.
- Statistical Analysis:
- Standard Deviation: Calculate the standard deviation of a dataset using the appropriate formula to understand the data’s dispersion.
- Percentages: Use formulas to express values as percentages of a whole, often helpful for comparing proportions.
- Conditional Formulas:
- IF Statements: Apply conditional formulas to perform actions based on specific conditions. For example, highlight cells that meet certain criteria or perform calculations only when certain conditions are met.
- Date and Time Calculations:
- Date Differences: Compute the difference between two dates to track durations or analyze time-related data.
- Date Functions: Utilize date functions to extract specific components (e.g., year, month, day) from date and time values.

- The boxes of the table consist of different types of information such as marks of a student, income of a company, production of some firm, expenditure on different items and so on.
- Generally the first row and column of the table denote the titles.
- The level of questions in tables may be higher or lower as compared to the other form of graphs. This is largely dependent upon the data given in the table and the way questions are framed.
Formulas are the backbone of effective data analysis and visualization within table charts. By leveraging mathematical calculations, you can transform your table charts into dynamic tools for making data-driven decisions. Whether you’re working with financial data, scientific observations, or any other dataset, understanding how to apply formulas effectively can unlock the full potential of table charts.

34%.Question 2.
|
(A) 4 AH
(B) 7 AH
(C) 32 AH
(D) 35 AH
Answer: Option C
Explanation:
The total sales (in thousands) of all the seven years for various batteries are:
For 4AH = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676
For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694
For 32AH = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901
For 35AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601
For 55AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.
Clearly, sales are maximum in case of 32AH batteries.
Question 3.
In case of which battery there was a continuous decrease in sales from 1992 to 1997? (A) 4 AH (B) 7 AH (C) 32 AH (D) 37 AH Answer: Option B Explanation: From the table it is clear that the sales of 7AH batteries have been decreasing continuously from 1992 to 1997. Question 4.What is the difference of average of 35 AH and 55 AH batteries in all the years? (A) 11 (B) 12 (C) 15 (D) 17 Answer : 11 Explanation : Total 35 AH batteries sold = 102+84+105+90+75+45+100 = 601 Average = 85.85 Total 55 AH batteries sold = 108+126+135+75+90+120+145 = 699 Average = 99.85 Difference of Averages = 99.85 – 88.85 = 11 Question 5.Calculate how much more or less batteries were sold in the year 1994 than in the year 1996? (A) 25 % more (B) 15.25 % more (C) 10 % less (D) 12.90 % less Answer : 12.90 % less Explanation : Batteries sold in the year 1994 = 525 Batteries sold in the year 1996 = 465 Difference = 525 -465 = 60 % difference = (60 / 465) * 100 = 12.90 % less |
