Part 2 | Average, Standard Deviation (SD) & Relative Standard Deviation (RSD) | Young Researchers
Average
The average, or mean, is a measure of the central tendency of a set of data. It is calculated by adding up all of the values in the set and dividing by the number of values.
Standard Deviation
The standard deviation (SD) is a measure of how spread out a set of data is. It is calculated by finding the average distance of each data point from the mean. A higher SD indicates that the data is more spread out, while a lower SD indicates that the data is more clustered around the mean.
Relative Standard Deviation
The relative standard deviation (RSD) is a measure of the SD relative to the mean. It is calculated by dividing the SD by the mean and expressing the result as a percentage.
The RSD is often used to compare the variability of different data sets, especially when the data sets have different means. A higher RSD indicates that the data is more spread out relative to the mean, while a lower RSD indicates that the data is more clustered around the mean.
