Mean and sd graph
WebAug 30, 2024 · The standard deviation represents how spread out the values are in a dataset relative to the mean. It is calculated as: Sample standard deviation = √Σ (xi – xbar)2 / (n-1) where: Σ: A symbol that means “sum” xi: The ith value in the sample xbar: The mean of the sample n: The sample size http://www.cookbook-r.com/Graphs/Plotting_means_and_error_bars_(ggplot2)/

The symbol σ (sigma) is often used to represent the standard deviation of a population, while s is used to represent the standard deviation of a sample. Variation that is random or natural to a process is often referred to as noise.
