Range: largest number minus the smallest number
39 - 19 = 20
your range is 20

26+19+23+39+31+34+23+25= 220

Kevin recorded the effects of violent video games on antisocial behavior.
den301095 [7]

Answer:

B.

Explanation:

Because the study is relying on the effects of violent video games and how it affects anti-social behavior.

If this was a math problem it'd be:

---> y= effect and signs of anti social behavior.

---> x= violent video games.

--->5= Hours spent playing. (Lets use 5 as a random number to write this as an equation then.)

Equation form:

Most likely would look something like this

(5x=y)

Hope this helped. I know it's late but it came up on my "Selected for you" section so I decided I'd answer it.
