Question 1

Write the names of a few trees you see around you. When you observe a tree on the way from your home to school (or while walking from one place to another place), record the data and fill in the following table:

a. Which tree was found in the greatest number?

b. Which tree was found in the smallest number?

c. Were there any two trees found in the same numbers?

Solution

We will observe trees around us and fill in the given table. Then we will answer questions based on our observations.

Step 1 — Observe and Record Trees

Let us walk from home to school. We will look for different types of trees. We will count how many of each type we see. Then we will fill in the table. Here is an example of how your table might look:

Diagram 1

| Tree | No. of Trees | | :-------- | :----------- | | Peepal | 5 | | Neem | 3 | | Mango | 7 | | Banyan | 2 | | Gulmohar | 3 |

Data collected from observation\boxed{\text{Data collected from observation}}

Step 2 — Find the Most Common Tree

We will look at the 'No. of Trees' column. We need to find the biggest number there. In our example, the numbers are 5, 3, 7, 2, 3. The biggest number is 7. The tree next to 7 is Mango.

Mango was found in the greatest number (in our example)\boxed{\text{Mango was found in the greatest number (in our example)}}

Step 3 — Find the Least Common Tree

We will look at the 'No. of Trees' column again. We need to find the smallest number there. In our example, the numbers are 5, 3, 7, 2, 3. The smallest number is 2. The tree next to 2 is Banyan.

Banyan was found in the smallest number (in our example)\boxed{\text{Banyan was found in the smallest number (in our example)}}

Step 4 — Check for Same Numbers

We will look for numbers that appear more than once. In our example, the numbers are 5, 3, 7, 2, 3. The number 3 appears two times. Neem has 3 trees. Gulmohar also has 3 trees.

Neem and Gulmohar were found in the same numbers (in our example)\boxed{\text{Neem and Gulmohar were found in the same numbers (in our example)}}

Answer

(a) This answer depends on your observations. Find the tree with the highest count in your table. (b) This answer depends on your observations. Find the tree with the lowest count in your table. (c) This answer depends on your observations. Check if any two trees have the same count in your table.

Q2

Take a blank piece of paper and paste any small news item from a newspaper. Each student may use a different article. Now, prepare a table on the piece of paper as given below. Count the number of each of the letters ‘c’, ‘e’, ‘i’, ‘r’, and ‘x’ in the words of the news article, and fill in the table.

a. The letter found the most number of times is _______.

b. The letter found the least number of times is _______.

c. List the five letters ‘c’, ‘e’, ‘i’, ‘r’, ‘x’ in ascending order of frequency. Now, compare the order of your list with that of your classmates. Is your order the same or nearly the same as theirs? (Almost everyone is likely to get the order ‘x, c, r, i, e’.) Why do you think this is the case?

d. Write the process you followed to complete this task.

e. Discuss with your friends the processes they followed.

f. If you do this task with another news item, what process would you follow?
