First you need to know the steps involved in getting the Mean Absolute Deviation, which are:
1 find the mean (average)
2. find the difference between each data value and the mean
3. take the absolute value of each difference
4. find the mean (average) of these differences
To do these things you need only two of Excel's functions. AVERAGE to get the mean and ABS to get the absolute value. Say your values are in the cells from A2 to A18. First you get the mean of those cells. Say we put this formula into cell A20. Then your formula in A20 would be:
=AVERAGE(A2:A18)
Combining steps 2 and 3, you could get the absolute of the difference for each value. Starting in cell B2, the cell beside the first value, you would put the following formula and then copy it down to B18:
=ABS(A$20-A2)
Then in B20 you you would put:
=AVERAGE(B2:B18)
That would give you your final result. In your instance you may need adjust the cell references.

How do you find out the z-score?

What does it mean to find a data point within one standard deviation of the mean?
The data point is close to the expected value.
IQ test scores are normally distributed with a mean of 100 and a standard deviation of 15 An individual's IQ score is found to be 110 Find the z-score corresponding to this value?
mean= 100 standard deviation= 15 value or x or n = 110 the formula to find the z-value = (value - mean)/standard deviation so, z = 110-100/15 = .6666666 = .6667
How do you find the sample size when given the standard deviation and the mean with a sample value?
You cannot from the information provided.
What is the mean absolute deviation of Victoria's science scores?
To calculate the mean absolute deviation (MAD) of Victoria's science scores, you first find the mean of her scores. Then, subtract the mean from each individual score to find the absolute deviations. Finally, calculate the average of these absolute deviations. Without the specific scores, I cannot provide a numerical answer, but this is the process to find the MAD.
What is the mean absolute deviation of the data set shown?
To calculate the mean absolute deviation (MAD) of a data set, first find the mean of the data. Then, subtract the mean from each data point to find the absolute deviations. Finally, take the average of these absolute deviations. If you provide the specific data set, I can help calculate the MAD for you.

Step 1: Find the mean Step 2: Find the deviation from the mean Step 3: Take the absolute value of the deviation Step 4: Find the mean of the absolute deviation. x----x-mean 63 63-63 0 69 69-63 6 62 62-63 -1 57 57-63 -6 64 64-63 1 mean = (63+69+62+57+64)/5 = 63 Taking the absolute deviations, we have 0,6,1,6,1 Averaging these deviations : (0+6+1+6+1)/5 =14/5 = 2.8 Mean absolute deviation = 2.8
What are the steps to find the mean absolute deviation?

How do I use mean absolute deviation?
The first step is to find out what the deviation is from: the mean, median, some other fixed value. Whatever it is, call it m.For each observation x, calculate the absolute deviation, which is x - m or m - x, whichever is positive or zero. Finally, calculate the mean value (arithmetic average) of this set.
How do you find absolute deviation?
You do not have absolute deviation in isolation. Absolute deviation is usually defined around some measure of central tendency - usually the mean but it could be another measure. The absolute deviation of an observation x, about a measure m is |x - m| which is the non-negative value of (x - m). That is, |x - m| = x - m if x ≥ m and m - x if x < m

How do you find the average absolute deviation?
Add all the absolute deviations together and divide by their number.
How do you find percent deviation?
to find percent deviation you divide the average deviation into the mean then multiply by 100% . to get the average deviation you must subtract the mean from a measured value.
How do you figure out mean absolute deviation?
Three steps:1. Find the mean of all values2. Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)3. Then find the mean of those distances
