Skewness in Statistics-Calculate Skewness in R
Skewness in Statistics, what is mean by skewness? Lack of symmetry of tails of a frequency distribution curve is known as skewness. The symmetry of tails means that the frequency of the points at equal distances on both sides of the center of the curve on the X-axis is the same. The area under the curve at equidistant intervals on both sides of t...

Kurtosis in R-What do you understand by Kurtosis?
Kurtosis means bulginess, It’s related to the peakedness of a frequency curve as compared to a normally peaked curve. If a frequency distribution curve is more peaked compared to normal peaked curve then it’s a Kurtic curve. If a frequency curve is more peaked than a normal curve then it’s called a leptokurtic curve and if it is less peaked...

Error Bar Plot in R-Adding Error Bars-Quick Guide
Error bar Plot, Error bars are visual representations of the variability of data and used on graphs to suggest the error in a reported measurement. They give a general idea of how precise a measurement is, or conversely, how far from the reported value the true value might be. Error bars regularly constitute one standard deviation uncertainty, on...
