#Box plot excel average and standard deviation code

This is shown in the following code snippet. The variance of the data is found by squaring the differences from the mean, adding them and then finding their average. This is given in the following code snippet. Then the mean is found by dividing the sum by the number of elements.

In the above program, first the sum of the data values is obtained. The standard deviation of these data values is 3.1232 Again, you can verify this number by using the QUARTILE.EXC function or looking at the box and whisker plot. This makes sense, the median is the average of the middle two numbers.

In simple terms, it tells you how spread out a collection of data points are. The higher the SD value wide the bell curve, and the smaller the SD value, the slimmer the bell curve is. In statistics, standard deviation is a measure of how dispersed a set of data is relative to its mean. These descriptive statistics computed by Excel are familiar, and Excel computes a number of additional values such as range, minimum, etc., that are self-explanatory except for 'Kurtosis' and 'Skewness'. Excel Standard Deviation Graph shape depends on the SD value. ExampleР В РІР‚СњР В РІР‚РЋloat val = Output The data values are: 12.5 7 10 7.8 15.5 You can verify this number by using the QUARTILE.EXC function or looking at the box and whisker plot. The standard deviation is 9.96, the variance is 99.14 and the range is 37. It is the square root of variance, where variance is the average of squared differences from the mean.Р В РІР‚СњР В РІР‚С› program to calculate the standard deviation is given as follows. Standard deviation is the measure of how spread out the numbers in the data are.
