Session 39: Introduction to statistics

Intro  Activity (15 minutes) 

Warm-Up Circle 

Activity 1:  Data About Us 

Students sit in a circle. Each student shares one fun fact (favorite color, hobby, pet, place etc.)

Teacher note down categories that appear repeatedly (e.g., favorite color) on the board

Ask: What do we notice?

(Building self-awareness and appreciating others’ interests)

Then ask: How can we organize this better?

Ask students to organize the data in their own way, then review their work and offer positive feedback 

Main Activity (65 minutes)

Activity 1 (25 minutes )

Ask a fun question:

What’s your favorite weekend activity?

• Give 4–5 options (e.g., Playing games, Watching TV, Reading, Drawing, Going out)
• Let students raise their hands for each category.
• Teacher writes the tally marks on the board.

Then ask: How can we organize this better?

Introduce the concept of a frequency table:

Activity 2 (25 minutes)

Classroom Survey & Frequency Table 

1. Divide class into small groups
2.  Each group chooses or is assigned a question (eg: favorite school subject, Favorite fruit, Number of pets at home, Birth month groups)

2. Considering another example: In a quiz, the marks obtained by 20 students out of 30 are given as:

(12,15,15,29,30,21, 30,30,15,17,19,15,20,20,16,21,23,24,23,21)

Expected Learning  Outcome:

Knowledge building-

• Concept of frequency table
