Easy Level Worksheet Questions
Part A: Subjective Questions
Note: Write the answers neatly on a sheet and submit them to your school subject teacher.
(1) What is the mean of 2, 4, 6?
Excellent! Mean = (2 + 4 + 6) ÷ 3 = 12 ÷ 3 = 4, demonstrating the basic formula for average.
(2) The marks in 5 subjects are 60, 70, 80, 90, 100. Find the range.
Perfect! Range = Highest - Lowest = 100 - 60 = 40, showing the spread of your academic performance.
(3) The runs scored in 3 matches are 40, 50, 60. Find the average runs.
Outstanding! Average = (40 + 50 + 60) ÷ 3 = 150 ÷ 3 = 50 runs per match.
(4) What is the mode of 3, 4, 4, 5, 6?
Brilliant! Mode = 4 because it appears twice, more frequently than any other number in the dataset.
(5) The temperatures for 3 days are 25°C, 28°C, and 27°C. Find the mean temperature.
Great work! Mean = (25 + 28 + 27) ÷ 3 = 80 ÷ 3 = 26.67°C
(6) In a bar graph, what does the height of the bar represent?
Correct! The height of each bar represents the frequency or count of data in that category.
(7) What is the median of 4, 8, 10?
Excellent! Since the data is already ordered, the median is the middle value, which is 8.
(8) Which type of graph uses rectangles to represent data?
Perfect! Bar graphs use rectangular bars with heights proportional to the values they represent.
(9) Write the range of 15, 20, 25, 30.
Great! Range = 30 - 15 = 15, showing the spread of this arithmetic sequence.
(10) Which central tendency is the most frequent observation?
Awesome! Mode identifies the value that occurs most frequently in a dataset.
Drag each concept to its correct category:
(1) The daily wages of 5 workers are ₹100, ₹120, ₹140, ₹160, ₹180. Find the mean wage.
Sum = 100 + 120 + 140 + 160 + 180 = ₹
Mean = 700 ÷
Perfect! The average daily wage is ₹140, representing the typical earnings of the workers.
(2) The heights (in cm) of students are 140, 150, 160, 170, 180. Find the range.
Range = Highest - Lowest = 180 - 140 =
Outstanding! The range of 40 cm shows the variation in student heights.
(3) Find the median of 3, 5, 7, 9, 11.
Given Data
Middle value =
Brilliant! In an odd-numbered dataset, the median is the middle value (3rd of 5 values).
(4) The shoe sizes of students are 6, 7, 7, 8, 6, 7. Find the mode.
Mode =
Excellent frequency analysis! Size 7 is the most common shoe size with 3 occurrences.
(5) Draw a bar graph for marks: English 60, Maths 80, Science 70. Find the subjects which are having highest and lowest marks.
Highest marks =
Subject with lowest marks =
Test your understanding with these multiple choice questions:
1. Which is not a measure of central tendency?
(a) Mean (b) Range (c) Mode (d) Median
Correct! Range measures spread of data, not central tendency.
2. The average of 5, 10, 15 is:
(a) 10 (b) 15 (c) 5 (d) 20
Correct! Average = (5 + 10 + 15) ÷ 3 = 30 ÷ 3 = 10.
3. The highest minus lowest value in data is called:
(a) Mean (b) Median (c) Range (d) Mode
Correct! Range is the difference between highest and lowest values.
4. The mean of first five natural numbers is:
(a) 2 (b) 3 (c) 4 (d) 5
Correct! First five natural numbers: 1,2,3,4,5. Mean = (1+2+3+4+5) ÷ 5 = 15 ÷ 5 = 3.
5. The mode of 4, 5, 6, 5, 5, 7 is:
(a) 4 (b) 5 (c) 6 (d) 7
Correct! 5 appears three times, more than any other number.
