Question

Katherine records her spelling scores for 7 weeks:11,15,20,15,18,17,19,15 ,find the range​

Answer 1

Since range = largest value - smallest value in a set of numbers
The range= 20 - 11
= 9

Answer 2

Hi there!

The question is asking us what the range is.

But what is the range? How do we find it?

Well, there's a formula that helps us find the range:

`\leadsto\quad\sf{Range=Largest~number-Smallest~Number}`

Let's apply this formula!

The largest number in the set is 20; the smallest one is 11.

So the range turns out to be:

`\leadsto\quad\sf{Range=20-11}`

`\leadsto\quad\sf{Range=9}`

Thererfore, the range of Katherine's spelling scores is 9.

Have a fantastic day!
