Step-by-step explanation: First of all the first step to find the mean absolute deviation you need to add 94, 86, 95, 99, 88 and 90 and then divide 552 which is the result that you get when you add by 6 getting an answer of 92. Second you need to find the distance or deviation but remember put those signs of absolute value when you find the answer.
remember the rule of absolute value which is that all numbers are always positive.
94-92= |2|
86 - 92= |6|
95-92=|3|
99-92=|7|
88-92=|4|
90-92=|2|
The final steps are to find the mean of the results you get when you subtract the deviation.
2+6+3+7+4+2= 24/6=4 is the absolute deviation
The mean absolute deviation is 4. The values differ from the mean by an average of 4.
Sorry if i got it wrong the last one and hopefully those are the correct answers.
