The number of students in the primary level (class 1 to 5) of a school are given below.
| Classes | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| No. of students | 45 | 30 | 50 | 25 | 15 |
(i) Draw a simple bar graph to show the number of students in different classes.
(ii) In which class are there the highest number of students?
(iii) How many students are there in the primary level?
Answer (1)
To answer the student's question, let's break it down into parts:
(i) Draw a simple bar graph to show the number of students in different classes:
To create a bar graph, follow these steps:
Title : Give your bar graph a title like "Number of Students in Each Class".
Axis : Draw two axes. The horizontal axis (x-axis) will represent the classes (1 to 5), and the vertical axis (y-axis) will represent the number of students.
Scale : Choose an appropriate scale for the vertical axis. Here, you can choose a scale of 5 or 10 to fit all the numbers up to 50.
Bars : For each class, draw a bar that matches the number of students:
Class 1: Draw a bar up to 45.
Class 2: Draw a bar up to 30.
Class 3: Draw a bar up to 50.
Class 4: Draw a bar up to 25.
Class 5: Draw a bar up to 15.
Label : Label each bar with the respective number of students at the top of the bars.
(ii) In which class are there the highest number of students?
By looking at the number of students, we can determine that Class 3 has the highest number of students with 50.
(iii) How many students are there in the primary level?
To find the total number of students in the primary level, add all the students from each class:
45 + 30 + 50 + 25 + 15 = 165
So, there are 165 students in the primary level.
