a) Class 5 students conducted a survey about which game they like the most. The table given below shows their responses.
| Games | Football | Cricket | Basketball | Volleyball |
| ----------- | -------- | ------- | ---------- | ---------- |
| No. of students | 15 | 12 | 10 | 6 |
Let's draw a bar graph to show the above information.
b) The average monthly attendance of class 5 in the first 4 months of a new academic session is given in the table.
| Months | Baishakh | Jestha | Asar | Shrawan |
| -------- | -------- | ------ | ---- | ------- |
| Attendance | 15 | 25 | 30 | 28 |
(i) Let's draw a bar graph of the given data.
(ii) In which month the average attendance was minimum or maximum?
(iii) In which month the average attendance was less than 25?
Answer (2)
a) Bar Graph for Favorite Games
To draw a bar graph, follow these steps:
Draw the Axes: Create two perpendicular lines to represent the horizontal (x-axis) and vertical (y-axis) axes.
X-axis: will represent the different games.
Y-axis: will represent the number of students.
Label the Axes:
X-axis: Label different categories: Football, Cricket, Basketball, and Volleyball.
Y-axis: Choose an appropriate scale (e.g., counting by 5's up to at least 15) and label it from 0 to 15.
Draw Bars: For each game, draw a bar that reaches the number of students who favored that game:
Football: A bar up to 15.
Cricket: A bar up to 12.
Basketball: A bar up to 10.
Volleyball: A bar up to 6.
Each bar should have equal spacing between them and must not touch each other.
b) Average Monthly Attendance(i) Bar Graph of Attendance Data
Similar to the games bar graph, follow these steps:
Draw the Axes: Create two perpendicular lines for the axes.
X-axis: This will represent the months (Baishakh, Jestha, Asar, Shrawan).
Y-axis: This will represent the attendance numbers.
Label the Axes:
X-axis: Mark for Baishakh, Jestha, Asar, and Shrawan.
Y-axis: Choose an appropriate scale (e.g., counting by 5's up to 30) and label it from 0 to 30.
Draw Bars: For each month, draw a bar that reaches the average attendance:
Baishakh: A bar up to 15.
Jestha: A bar up to 25.
Asar: A bar up to 30.
Shrawan: A bar up to 28.
Ensure bars are spaced evenly apart.
(ii) Minimum and Maximum Attendance
Maximum Attendance: Asar, with an attendance of 30 students.
Minimum Attendance: Baishakh, with an attendance of 15 students.
(iii) Months with Attendance Less Than 25
By examining the data:
Baishakh ) had an attendance of 15 which is less than 25.
So, the month of Baishakh had the average attendance less than 25.
;
To draw bar graphs for favorite games and monthly attendance, follow structured steps involving axes, scaling, and bar heights based on student preferences and attendance figures. Maximum attendance occurred in Asar (30), while the minimum was in Baishakh (15), with Baishakh having attendance less than 25. Each graph should have labeled and evenly spaced bars for clarity.
