Class 6 Maths Data Pictures Questions and Answers
Question 1.
Look at the graph that shows a person’s income for the past month.
What all can be found in this?
The highest income is in April (₹ 50000)
The lowest income is in May and June (₹ 25000)
The difference between the income in February and May is ₹ 5000
After February, there is a good increase in income.
What all can be found from this?
The highest expense is in May, and the lowest expense is in June.
The expenses in February and March are the same.
From March to May, the expenses keep increasing.
In June, the expenses drop sharply.
Now, let us draw these two graphs together.
This graph can be used to compare income and expenses.
The largest difference between income and expenses is in February.
The months in which the expense is higher than the income are February and May.
Class 6 Maths Chapter 12 Notes Kerala Syllabus Data Pictures
→ A pictograph is a way of showing data using pictures or symbols. Each picture stands for a certain number of things, which makes the information easy to understand.
→ A line graph is a graph that uses points and straight lines to show how something changes over time.
→ A data picture means showing information using pictures or symbols so that it becomes easy to understand.
Data means information collected in the form of facts or numbers. To understand data easily, we show it using pictures. Such picture-based representations are called pictographs. Pictographs use symbols or images to show numbers, making the data simple to read and compare. They help us understand information quickly and clearly.
Line Graphs
Bar Graph
We have learned in the previous class how to find information from a table and how to record information into a table. In the same way, we also learned how to represent information using bar graphs. Look at this information. The table shows the number of children in a school over the past few years.
Using this information, we can draw a bar graph.
From this bar graph, we can easily find the information about the number of children.
Now look at this table.
The table shows the amount of rainfall received in a place last year.
Using this information, draw a bar graph and prepare some questions based on the picture.
In which month did it rain the most?
In which month did it rain the least?
In which months did it rain the same amount?
What is the total amount of rainfall in the whole year?
What is the difference between the rainfall in the month with the least rain and the month with the most rain?
Line Graphs
The information given in the table above changes with time. These are usually shown in another method. As we did in the bar chart, the months should be shown in one row, and the amount of rainfall on the other side should keep equal spacing. The amount of rainfall in the table ranges from 5 to 40, so we can take the scale from 0 to 50. Since the rainfall is given at intervals of 5 centimeters, we can take 5, 10, 15, 20… and so on.
This kind of picture is called a line graph. From this graph, we can easily understand several things at a glance. The amount of rainfall decreases from January to February, then gradually increases for the next three months. After that, it decreases for three months, increases again in October, and finally decreases in November and December to the lowest level.
Answer the following questions by looking at the graph:
Question 1.
In which month was the rainfall the highest?
Answer:
June
Question 2.
Which month had the least rainfall?
Answer:
March and December
Question 3.
How many centimeters was the highest rainfall?
Answer:
40 cm
Question 4.
How many centimeters was the lowest rainfall?
Answer:
5 cm
Question 5.
Which months can be called the rainy season?
Answer:
June, July, August
Question 6.
In which months was the rainfall the same?
Answer:
January – September, February – November
What is the special feature of the temperature line graph here?
The temperature gradually increases, reaches the maximum, and then decreases.
After it decreases, there is no month in which it rises again.
Question 1.
What is the highest temperature in degrees Celsius?
Answer:
44°C
Question 2.
In which month was it recorded?
Answer:
May
Question 3.
Which months of the year can be called the summer season?
Answer:
March, April, May
Question 4.
Between which consecutive months did the temperature increase the most?
Answer:
February – March, March – April
Question 5.
And between which consecutive months did it decrease the most?
Answer:
November – December
From this graph, we can find the following:
The highest temperature is 26 degrees Celsius
The lowest temperature is 5 degrees Celsius
The lowest temperature occurs in January and December
The temperature gradually increases from January, reaches its maximum in June, and then starts decreasing.
June and July have the same temperature
May and August also have the same temperature
The smallest difference in temperatures is seen between May – June and July – August
The largest difference in temperature between two consecutive months is between October and November
The least difference is between January – December and June – July
Here, the high temperature and the low temperature are drawn together in a single graph.
By looking at the graph, we can find these facts.
The four months in which the difference between the high temperature and the low temperature is the greatest are from January to April
The four months in which this difference is the smallest are from June to September
The high temperature remained unchanged in two consecutive months – July and August
The low temperature remained unchanged in two consecutive months – June and July. What else can we find?
The lowest temperature is in January and December.
The difference between the highest and lowest temperatures in June is 14°C.
Now let’s write these in a table and check whether the above statements are correct.
What all can be understood from this graph?
The overs are marked at intervals of 5 and the runs are marked at intervals of 50.
India won the match by scoring more runs than New Zealand before reaching 50 overs.
New Zealand lost 7 wickets, and India lost 6 wickets (as shown by the number of red dots)
New Zealand scored more runs in the first 10 overs.
Between the overs 5 – 10, 10 – 15, and 25 – 30, India’s total runs at one stage reached the same point as New Zealand‘s earlier total.
After that, India’s total never fell below New Zealand’s total at any stage of the match.
After the 35th over, India’s score became much higher than New Zealand’s.
After the 25 -30 overs, India lost a wicket in the 40th over.
The first Indian batter scored a century (because India’s first wicket fell after 100 runs, and the first three red dots appear on the red line).
India lost two wickets between the 20th and 25th overs.
The first New Zealand batter scored more than 50 runs.
India lost another wicket between the 25 – 30 overs.
