Interpretation of a Pictograph 
Data handling involves organizing and interpreting information through various methods. For example, cricket scoreboards record not just wins and losses but detailed statistics like runs, balls faced, and wickets taken.
Similarly, tables in daily life, such as attendance records or exam marks, organize numbers and figures to provide useful insights. These tables provide ‘Data’.
A data is a collection of numbers gathered to give some information.
Example of Recording Data
Imagine a teacher wants to find out how many students prefer each mode of travel for a class trip. The options are bus, bike, car, and walk.
Organizing data means arranging information in a clear way to make it easy to count and understand.
Organizing data helps make it easier to understand by putting it into a specific order. This can be done in alphabetic order and numerical order.
A table is used to collect and organize information by counting responses.
Tally marks are a simple way to count and organize data.
Example: A survey was conducted among a few people regarding their favourite beverages. The below tally marks table shows the data:
(i) How many more people like green tea than coffee?
(ii) How many people like tea?
(iii) How many total people were surveyed?
Ans:
(i) Number of people like green tea = 9
Number of people like coffee = 8
∴ One more people like green tea than coffee
(ii) Number of people who liked tea = 19
(iii) Total number of people surveyed = 40
Example:
In the image provided, the picture drawn in front of each sport represents the number of students playing it. We can eaily count this.
Baseball is played by: 6 students (count the number of pictures drawn)
Soccer is played by: 8 students
Basketball is played by: 3 students
A pictograph uses pictures to show data, where each picture represents a set number of items. A key explains how many items one picture stands for, making it easier to represent larger quantities.
Example: If the key shows that one apple picture equals 10 apples, and you see 3 apple pictures in the pictograph, it means there are 30 apples in total.
Q1:The number of cars parked in a parking lot every day is given in the pictograph.
(i)Find the day when the highest number of cars are parked and how many?
(ii)When the least number of cars did park?
Ans:
(i) In the above pictograph one car represent 5 cars.
As there is the maximum number of cars is shown on Tuesday so the highest number of cars was parked on Tuesday.
Hence, 40 cars were parked on Tuesday in the parking lot.
(ii) Least number of cars were parked on Monday as there are only 4 pictures of cars are shown on that day.
Q2: The sale of electric bulbs on different days of a week is shown below:
Observe the pictograph and answer the following questions:
(i) How many bulbs were sold Friday?
(ii) On which day maximum numbers of bulbs were sold?
Ans:
(i) Number of figures of bulbs shown against Friday = 7
Given: 1 figure = 2 bulbs
Therefore, Total number of bulbs sold on Friday = 2 x 7 = 14
(ii) Sunday shows the maximum number of figure of bulbs, i.e. 9
Therefore, On Sunday, maximum bulbs were sold.
