Samacheer Kalvi Class 4 Maths Solutions Term 1 Chapter 6 Information Processing Exercise 6.2

Question 1. Bar diagram of a student first term scores are given.
A bar diagram shows a student's scores in different subjects. The approximate scores are: Tamil (80), English (65), Maths (90), Science (85), and Social Science (70).
(a) Which subject is the highest score?
(b) Which subject is the lowest score?
(c) Which subject is the same score?
Answer:
(a) The subject with the highest score is Maths. This is because its bar goes up to the highest point on the chart, showing 90 marks.
(b) The subject with the lowest score is English. Its bar is the shortest, reaching only 65 marks.
(c) There are no two subjects with the exact same score shown in this bar diagram. All subjects have different scores. The chart clearly shows each subject having a unique bar height.
In simple words: Look at the height of each bar in the chart. The tallest bar shows the highest score, and the shortest bar shows the lowest. If two bars are the same height, they have the same score.

🎯 Exam Tip: When reading a bar diagram, always check the labels on both the horizontal (x) and vertical (y) axes carefully. The height of each bar directly corresponds to the value it represents.

Question 2. The score card of the players in a cricket match is given.

Draw a Bar diagram.
Answer:
The bar diagram above visually represents each player's score. This type of graph makes it easy to compare scores at a glance.
In simple words: We draw bars on a graph. Each bar's height shows how many runs a player scored. Taller bars mean more runs.

🎯 Exam Tip: When drawing a bar diagram, always choose an appropriate scale for the axes. Make sure to label both axes clearly and give a title to the diagram for better understanding.
