Frequency tables and grouped data

What you'll learn

1. 1

   Imagine you're counting how many pets your class has. You tally up each pet type — that's a frequency table! 🐱🐶🐰

2. 2

   What does 'frequency' mean in a frequency table?

3. 3

   Build a frequency table for these pets: 5 dogs, 3 cats, 7 fish. Drag the numbers to match each pet.

4. 4

   Let's group ages into intervals: 0-9, 10-19, 20-29. Here's how we tally them.

5. 5

   Now you try! These ages are: 4, 7, 12, 15, 22, 28. Group them into 0-9, 10-19, 20-29. Tap the correct frequency for 10-19.

6. 6

   In a grouped frequency table, what do the groups (like 10-19) include?

7. 7

   If the frequency for 20-29 is 3, how many people are in that age group?
