When Results Are Different (Variation and Explanation)
When Results Are Different (Variation and Explanation)
Welcome to the Lesson
You tested Mr. Bee’s predictions and collected data.
You probably noticed something important:
The results were close to your predictions but not exactly the same every time.
Today’s lesson is about why that happens.
This is not a problem.
This is how real experiments work.
Mr. Bee Notices Something Strange
Mr. Bee ran the same test more than once.
Mr. Bee used the same power setting.
Mr. Bee followed the same steps.
But the results were a little different each time.
Mr. Bee wonders: “Did I make a mistake or is something else happening?”
Today’s Big Idea
Small differences are part of real-world testing.
These differences are called variation.
Variation does not mean something is wrong.
Variation helps us understand systems better.
By the End of This Lesson, You Will Be Able To
- Explain why results can be different
- Compare multiple test results
- Use math words to explain variation
How This Lesson Works
- Watch Mr. Bee notice differences
- Look at repeated test results
- Explain why results changed
- Answer a short quiz
You can move at your own pace. Enjoy it!
