🌟 Mean, Median, Mode & Range 🌟

Hi my super Grade 6 statisticians! 👋

Today we learn four important tools to describe a set of numbers: Mean, Median, Mode, and Range. They help us understand data better — like test scores, heights, or how many goals players score!

📊🔢

1. What Do They Mean?

Example Data: 5, 7, 7, 8, 12

Mean (Average)
Add all numbers and divide by how many there are.
(5+7+7+8+12) ÷ 5 = 7.8

Median (Middle)
Put numbers in order and find the middle one.
5, 7, 7, 8, 12 → 7

Mode (Most Common)
The number that appears most often.
7 appears twice

Range (Spread)
Biggest number minus smallest number.
12 − 5 = 7

2. Let’s Practice Together! 🎉

Question 1

Data: 10, 12, 12, 15, 21

Mean = 14
Median = 12
Mode = 12
Range = 11 ⭐

Question 2

Test scores: 85, 90, 78, 92, 85

Mean = 86
Median = 85
Mode = 85
Range = 14 ⭐

Question 3

When would the median be more useful than the mean?

When there are very high or low numbers (outliers) that make the mean not fair ⭐

3. In Real Canadian Life 🇨🇦

• Teachers use mean to find class average
• Hockey coaches look at median goals
• Stores use mode to know most popular size
• Weather reports show temperature range

You are now a Data Statistics Expert! 🌟

Amazing work! You can now find mean, median, mode, and range like a pro.

Try finding the mean, median, mode and range of your family’s ages this week!

Love and proud high-fives,
Mrs. Brenda ❤️
