3.06 Quiz: Scatter Plots Wrap-Up

Answer 1

Scatter plots used dots to show the relationship between its variables.

The most appropriate scale is (b) 0 to 4 with intervals of 0.2

Given

$Water \to 2, 1, 1.5, 4, 3,1,5$

$Fluoride \to 1.1, 0.8, 1.2, 3.2, 1.6, 0.2, 3.6$

From the given dataset, we have:

$Least = 0.2$

$Highest = 5$

The best scale to use if 0 to 5, as it covers the given range.

Since, scale 0 - 5 is missing from the option,

The next scale to consider is 0 to 4

Also from the dataset, majority of the data elements are approximated to 1 decimal place.

This means that an interval of 0.2 would be more appropriate than an interval of 2.

Hence, the most appropriate option is (b) 0 to 4 with intervals of 0.2
