Dispersion is a statistical calculation that allows you to tell how far apart your data is spread. Many different ways are available to calculate dispersion, but two of the best are the range and the average deviation. The range is the difference between the highest and lowest value of your ...
Open Microsoft Excel and load a worksheet that contains the data you wish to calculate dispersion statistics for. Video of the Day Step 2 Select a blank cell and label it "Data Variance," replacing "Data" with the name of the data being analyzed. The variance of a sample of data is a ...
There are different ways to calculate lexical dispersion in a corpus. One of the simplest ones is to count the number of portions of the corpus in which the word is present. The chapter describes the principles underlying inferential statistics. It shows that data from corpora correspond to ...
To calculate the average and standard deviation: 1. Calculating the Average in Excel 1.1. Computing the Average Manually Use the formula: =SUM(D5:D12)/COUNT(D5:D12) The SUM function returns the total scores and the COUNT function counts the number of scores. Total scores are divided by...

The pooled standard deviation is the way to go. Let’s see how. Overview: What Is a Pooled Standard Deviation? The definition of thestandard deviationis the average distance each data point is away from the mean of the data. It is a measure of the variation, spread, or dispersion of ...
The interquartile range (IQR), represents the middle 50 percent of a data set. To calculate it, first order your data points from least to greatest, then determine your first and third quartile positions by using the formulas (N+1)/4 and 3*(N+1)/4 respectively, where N is the number...
If a field has any nulls, the tool will not be able to calculate an index for the records. Consider using theFill Missing Valuestool to impute a value, if appropriate, or find supplemental data if not. How the tool combines variables into an index ...
The Sharpe ratio usesstandard deviation, which is a mathematical measure of the dispersion of values within a range. To calculate standard deviation, first find the mean by adding all values and dividing by the number of values in the dataset. Then calculate the variance for each value by subt...
The average deviation in Excel, calculated using the AVEDEV function, is the mean of the absolute differences between each number in a set and the central number, typically the average of the set. It provides a measure of dispersion within a dataset. ...
