Measures of Variation
![What is Variation?](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/13218.jpg)
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic…
![Range](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/13219.jpg)
The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in…
![Standard Error of the Mean](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/13221.jpg)
The sampling variability of a statistic is defined as how much the statistic varies from one sample to another. The sampling variability of a…
![Calculating Standard Deviation](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/13222.jpg)
The standard deviation is the most common measure of variation. It is a value that tells us how far a data value is from the mean value in a dataset.…
![Coefficient of Variation](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/13224.jpg)
The coefficient of variation measures the dispersion of the data points or distribution around the mean. Using the coefficient of variation, we can…
![Range Rule of Thumb to Interpret Standard Deviation](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/13225.jpg)
The range rule of thumb in statistics helps us calculate a dataset's minimum and maximum values with known standard deviation. This rule is based…
