Scatter Plots, Regression and Outliers

Describe a scatter plot properly, interpret the correlation coefficient, use the least squares line to predict, and know when a prediction is worthless.

By the end, you can

describe correlation from a scatter plot, interpret r and use a regression line to make and judge a prediction.

Scatter Plots, Regression and Outliers

QUEST MATH-P2-REGRESSION

Two things, measured together

A scatter plot asks whether two quantities move together. Hours studied and marks. Rainfall and yield. Age of a car and its price. 📈

The maths gives you a line and a number. Knowing what they mean — and what they do not mean — is where the marks are, and where the real-world value is too.

Scatter Plots, Regression and Outliers: questions

How long does Scatter Plots, Regression and Outliers take?
About 14 minutes: 9 short lessons, 2 quick checks and a 5-question final challenge. Your progress is saved after every step, so you can stop and carry on later.
How much does Scatter Plots, Regression and Outliers cost?
R19, paid securely online, or 19 learning credits from your wallet. You pay once: if you don’t pass the challenge, you try again at no extra cost.
What do I need to pass?
4 out of 5 on the final challenge (80%). The quick checks along the way help you learn and do not count towards your mark.
Is the certificate accredited?
No. A MicroQuest is informal learning. Your certificate proves you completed it and has a number and QR code anyone can verify, but it is not an accredited qualification or SETA/QCTO credits, and it says so.
Can I do it on my phone?
Yes. Tap Start to learn in your phone’s browser, or send QUEST MATH-P2-REGRESSION to 076 263 6000 on WhatsApp. It is the same MicroQuest and the same certificate either way.
