Although I can't see the data. First you find the mean. After that you grab the numbers from the data and subtract it from the mean then divide it by the amount of numbers you used to add.

thanks

anonymous · Answer

$$\frac{ 09+115+203+30 }{ 4 } = ?$$

anonymous · Answer

that's not it. After you find this answer. you still have more steps to find the absolute deviation

anonymous · Answer

ok and those steps are?????

anonymous · Answer

$$\frac{ |09-?|+|115-?|+|203-?|+|30-?| }{ 4 } = $$

I basically just gave you 90% of the process. All you need is a calculator and done.

the question mark is the answer you need from a calculator or just your head. Then whatever you get on that question mark plug into the next division and you will have you answer.
