Question 2.
Calculate the total runs secured in each over and shorten the table like this.
Calculate the total runs secured in each over and shorten the table like this.
i) How many runs were scored in the first ten overs?
ii) In how many overs were more than 6 runs scored?
iii) In how many overs were less than 6 runs scored?
iv) What other information can we get from this shortened table?
Answer:
Over 1: 2 + 0 + 0 + 2 + 0 + 0 = 4
Over 2: 1 + 4 + 0 + 2 + 0 + 0 = 7
Over 3: 0 + 0 + 4 + 0 + 1 + 1 = 6
Over 4: 4 + 0 + 2 + 0 + 1 + 0 = 7
Over 5: 0 + 0 + 4 + 1 + 0 + 3 = 8
Over 6: 2 + 0 + 2 + 2 + 0 + 0 = 6
Over 7: 1 + 0 + 4 + 0 + 2 + 1 = 8
Over 8: 2 + 0 + 2 + 0 + 3 + 0 = 7
Over 9: 0 + 0 + 6 + 2 + 2 + 0 = 10
Over 10: 6 + 0 + 0 + 4 + 0 + 2 = 12
i) The total runs scored = 4 + 7 + 6 + 7 + 8 + 6 + 8 + 7 + 10 + 2 = 75
So, the total runs scored in the first ten overs is 75.
ii) Over 2-7 runs, Over 4 -7 runs, Over 5 – 8 runs, Over 7 – 8 runs, Over 8 – 7 runs, Over 9 – 10 runs, Over 10 – 12 runs
There are 7 overs with more than 6 runs scored.
iii) Overs with less than 6 Runs Scored Over 1-4 runs
iv) There is 1 over with less than 6 runs scored.
Other information We Can Get from the Shortened Table,
- Average runs per over.
- Identification of the highest-scoring over (Over 10, with 12 runs).
- Consistency of the scoring rate (fluctuation of runs over the overs).
Question 3.
The graph below shows the number of cars a company manufactured in the past few years:
i) In which year was the most number of cars made? How many cars were manufactured?
ii) And in which year was the least number of cars manufactured? How many cars were manufactured?
iii) How many cars less than those made in 2018 were made in 2023?
Answer:
i) The year with the most cars manufactured is 2019
No of cars made =14,500 cars
ii) The year with the least cars manufactured is 2020
No of cars made = 10,500 cars
iii) No of car made in 2018 = 13,000
No of car made in 2023 = 12,500
The difference is 13,000 – 12,500 = 500, which means 500 less cars were made in 2023 compared to 2018.
Question 4.
The graph below shows the units’of electricity consumed during various months of a year:
i) In which months was the maximum electricity used?
ii) In which months was it the minimum?
iii) What is the difference between the maximum and minimum?
iv) Are there any months in which the same units of electricity was used?
v) What is the total number of units used in this whole year?
Answer:
i) The maximum electricity consumption occurred in March and April, each.
ii) The minimum electricity consumption occurred in September, October, November, and December
iii) Maximum unit of electricity consumed =340 Minimum unit of electricity consumed =290
The difference between the maximum and minimum = 340 – 290 = 50 units
iv) Yes, September,October,November and December.
v) 310 + 340 + 330 + 300 + 290 + 290 = 1860 units.
The total electricity used in the whole year =1860 × 2 = 3720 unit
Question 5.
The graph below shows the number of girls and boys in classes 1-7 in a school:
Answer:
i) Class 3, Difference = 75 -70 = 5 ;
ii) Difference between the number of girls and boys the most = Class 1
Difference between the number of girls and boys the least = Class 2, 3 and 6
iii) Total number of girls in all these classes = 65 + 65 + 70 + 70 + 100 + 115 + 95 = 580
iv) Total number of students = 1100

Class 5 Maths Chapter 12 Notes Kerala Syllabus Tables and Graphs
In this chapter, we will learn how to understand and use tables and graphs to show information clearly. Here are the main ideas:
- Learn how to look at tables and find answers by comparing information.
- Understand how to show data using pictures like charts, graphs, and diagrams.
- See how bar graphs use bars to compare different groups or amounts.
By the end, you will be able to read tables and create simple graphs to show information in a clear way.
Tables
The given table provides a general overview of Class 5’s performance in the math exam by grouping students according to their grades.
While it doesn’t offer the detailed explanation found in the larger table, which would list each student’s individual grade, it still allows us to understand important aspects of the class performance. The general information that we get from this table is as follows,
- B is the grade that most students got.
- E is the grade that the least number of students got.
- The number of students who got A or B is more than the number of students who got C, D or E.
- The number of students who got A, B or C is four times the number of students who got D or E.
The table confirms there are 35 students in total, which is the basis for these percentages and observations.
We can combine all three tables into one
The information that we get from the completed table,
This table helps in assessing and comparing the performance across different grades and identifying which students might need more support or attention.
- It also highlights the general trend of student performance, which seems strong in higher grades, with a few students who may benefit from additional resources.
- Grade A is most common in Class 7, with 12 students achieving it. Class 6 follows closely with 10 students, and Class 5 has 9 students.
- Grade B is quite consistent across the three classes, though Class 6 has the most students (12) with this grade.
- The lowest grades, D and E, are generally less frequent, indicating fewer students in all classes are struggling significantly.
Data Pictures
A “Data Picture” is a visual representation of data that helps to communicate information in an easily understandable way. Data pictures can include various types of charts, graphs, and diagrams that display numerical or categorical data visually.
Common examples of data pictures include bar charts, pie charts, line graphs, histograms, scatter plots, and infographics.
A bar graph, is a visual representation of data that uses rectangular bars to show the frequency, count,- or other measures for different categories or groups. Each bar’s length or height is proportional to the value it represents, making it easy to compare data across categories. ,
England batted first in a T20 match against India. The runs they scored in each over is given in this table :
- Along a horizontal line at the bottom, numbers from 1 to 20 are marked at the same distance apart. This is to show the number of overs.
- Along a vertical line on the left, numbers from 1 to 21 are marked at the same distance apart. This is to show the number of runs scored.
- Then at the position showing each over, rectangles are drawn with heights up to the number on the vertical line showing the number of runs scored in that over. All these rectangles are of the same width.
