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.

To Find Average Deviation 1. Find the average value of your measurements. 2. Find the difference between your first value and the average value. This is called the deviation. 3. Take the absolute value of this deviation. 4. Repeat steps 2 and 3 for your other values. 5. Find the average of the deviations. This is the average deviation The average deviation is an estimate of how far off the actual values are from the average value, assuming that your measuring device is accurate. You can use this as the estimated error. Sometimes it is given as a number (numerical form) or as a percentage. To Find Percent Error 1. Divide the average deviation by the average value. 2. Multiply this value by 100. 3. Add the % symbol.

Standard deviation is a statistical tool used to determine how tight or spread out your data is. In effect, this is quantitatively calculating your precision, the reproducibility of your data points. Here's how you find it: 1). Take the average of all the data points in your set. 2). Find the deviation of each point by finding the difference between each data point and the mean. 3). Add the squares of each deviation together. 4). Divide by one less than the number of data points. If there are 20 data points, divide by 19. 5). Take the square root of this value. 6). Done.

It depends on the data. The standard deviation takes account of each value, therefore it is necessary to know the values to find the sd.

The Standard Deviation will give you an idea of how 'spread apart' the data is. Suppose the average gasoline prices in your town are 2.75 per gallon. A low standard deviation means many of the gas stations will have prices close to that price, while a high standard deviation means you would find prices much higher and also much lower than that average price.

To calculate the average deviation from the average value, you first find the average of the values. Then, subtract the average value from each individual value, take the absolute value of the result, and find the average of these absolute differences. This average is the average deviation from the average value.

A standard deviation calculator allows the user to find the mean spread away from the mean in a statistical environment. Most users needing to find the standard deviation are in the statistics field. Usually, the data set will be given and must be typed into the calculator. The standard deviation calculator will then give the standard deviation of the data. In order to find the variance of the data, simply square the answer.

The data point is close to the expected value.

No, you have it backwards, the standard deviation is the square root of the variance, so the variance is the standard deviation squared. Usually you find the variance first, as it is the average sum of squares of the distribution, and then find the standard deviation by squaring it.

Standard deviations are measures of data distributions. Therefore, a single number cannot have meaningful standard deviation.

Did you mean to ask: "What is standard deviation, and what are it's advantages and disadvantages" ? Standard deviation is a measure of how "spread out" a set of data is. If it is large, you have a large range of numbers. If it is small, most of your data points are close to the average. To find it, you need to subtract the "mean" (average) of the data from each data point, square your answers, add them all together, divide your answer by the number of data points minus 1, and take the square root. For a better explanation of how to find it, have a look here, see the related link below. So it's advantage is, it gives you a better picture of your data than just the mean alone. Disadvantages would be that it doesn't tell you the full range of the data, and it can be effected by "outliers" (rare numbers much smaller or larger than everything else in the data set) to give a skewed picture.
