Answer 2

So when you have a scatter plot, you're going to have points on a graph

If the points are all close to each other, they're called clusters

If there are points that are far away from the rest, those are your outliers
Think of outliers as your outcasts
They're going to be away from the clusters

so for part A
what is the group of points labeled T called?
What is the point labeled R called?

Which one is a cluster and which one is an outlier

Answer 3

t cluster and r's outlier?

Answer 4

You got it!

Answer 5

Answer 6

we haven't finished part A)
