Mean, Median and Mode:The mean, median, and mode are three measures of the central tendency of a sample or population. They are determined with the intention of analyzing the data, for example identifying whether or not it is symmetric....
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the va...

The mean (M) ratings are the same for each group – it’s the value on the x-axis when the curve is at its peak. However, their standard deviations (SD) differ from each other. The standard deviation reflects the dispersion of the distribution. The curve with the lowest standard deviati...

Does md4RSA mean that the information in the request was hashed with md4 and then encrypted with RSA? And is the Signature 70 82 [...] d0 23 the result of this calculation? Is there any way to manually decrypt the signature with the private key and get the original md4 hash? What...
Let X and Y be two independent random variables such that E(X) = E(Y) = 4 and Var(X) = Var(Y) = 2. Calculate E(U), E(V), and Var(U). Mean and Standard Deviation: The average of a data set is referred to as the ...

DaliyMeanConc() calculates daily mean concentration of 6 pollutants. Note that average O3 concentration for one day is presented by maximum 8-hour average concentration. Note: units of SO2, NO2, PM10, PM2.5 and O3 input are μg/m3 unit of CO is mg/m3 library(CNAQI) C <- rnorm(24...
Normal distribution curves with varying means and standard deviations (blue, central curve: mean = 0, SD = 1; green, right-most curve: mean = 1, SD = 0.5; purple, left-most curve: mean = -2, SD = 1.5) Sometimes, for a given data point, it is useful to know how its value comp...
