The range is the distance between the minimum data value and the maximum: [tex]\text{Maximum value}-\text{Minimum value}=\text{Range}[/tex]
[tex]\text{Given values: }3, -9, 7, -1, 5, -4, -2[/tex]
Your minimum value is -9.
Your maximum value is 7.
Therefore: [tex]\text{Range}\rightarrow\text{Maximum value}-\text{Minimum value}\rightarrow7-(-9)[/tex]
[tex]\rightarrow\text{Subtracting Negative Values}\rightarrow7+9=16[/tex]
**Subtracting a negative value [tex]-a[/tex] is like adding the product [tex](-1)(-a)[/tex], which would translate to the same thing as adding the product [tex](1)(a)[/tex], or adding [tex]a[/tex].
