Additional Practice Questions
Create a bar chart showing the number of children who prefer Mathematics, Languages, Arts, and Physical Education.
easyAnswer: A bar chart can be created where the X-axis represents the subjects and the Y-axis represents the number of children. Bars should be drawn to the height corresponding to the number of votes received by each subject.
If 25 children like Mathematics and 15 like Arts, what is the total number of children who enjoy these two subjects?
easyAnswer: The total number of children who enjoy Mathematics and Arts is 40.
Analyze the data collected about game preferences (Chess and Cricket) and determine why more boys or girls might prefer a particular game.
mediumAnswer: The analysis should consider the number of boys and girls playing each game, observing which gender predominates in Chess or Cricket and proposing reasons such as popularity of games at home or among peers.
Design an activity using a pictograph to compare the number of books read by different students over a month.
hardAnswer: In a pictograph, use symbols like books to represent a set number of books read, placing them against each student's name for a clear visual comparison.
If 12 students like both Mathematics and Arts, and 8 students like only Mathematics, how many students like Arts in total?
mediumAnswer: If 8 students like only Mathematics, and 12 like both subjects, the number of students who like Arts can be more or equal to 12. The solution requires additional data.
