.5, 3.2, 3.8, 3.5, 2.8, 4.0 Find the mean absolute deviation. (Round your answer to the nearest hundreth.)
when finding the mean..add all the values and divide it by the total number of your sample.
Whip out your calculator and do the ff: 1. Find the mean of the values. (Call this \(\mu\).) 2. Compute each of the ff: \(\large |0.5-\mu|, |3.2-\mu|, |3.8-\mu|, |3.5-\mu|, |2.8-\mu|, |4-\mu|\). 3. Add these. That's how you get mean absolute deviation.
Oops. Step 3 should have been "Find the mean of these".
? lost
Where, exactly?
so its 22.3
Hold on, lemme check.
ok
sooooooooo ?
Nope, it's approximately 0.88. Could you tell me what you did?
i added The Numbers up
can you show me how you got 0.88
Okay. So the mean of the numbers is 2.96667... And then I get all of the numbers I mentioned in my first post. Then I got the mean of all these numbers, and that's 0.88
Did You Round It ?
Only for the last part. For everything else, I used all the decimal points.
how do you get the mean of something ?
Add all the values whose mean we want, then divide by the number of the values. Example: The mean of 1, 3, 5, and 7 is (1+3+5+7)/4=4. Okay so far? :)
