The XXXXXXXX XXXXXXXXX shows how XXXX XXXXXX in a XXXX XXXXXX from the mean of the list XX XXXXXX(Martinez, M. N., & Bartholomew, X. J. XXXX). It XX simply XXX square root XX variance. XX XX found by determining XXX XXXXXXXXX between XXXX XXXX XXXXX XXXXXXXX XX XXX mean. If XXX XXXX points XXX XXXXXXX from the mean, XXXXX XX XXXXXX XXXXXXXXX within the XXXX XX values.
X XXX value of the XXXXXXXX XXXXXXXXX means XXXX the data points are close XX the mean. XXX mean XX XXXX XXXXXX XXX XXXXXXXX XXXXX. X high XXXXXXXX deviation XXXXX XXXX the XXXX points areXXX XXXX out over a XXXXX XX XXXXXX. XXXXXXXX XXXXXXXXX as a measure XX XXXXXXXXXX XX XXXXX if XXX XXXX is continuous, XXX is XXX XXXXXXXXXXX data. Also, XXX standard XXXXXXXXX is right XXXX XXX XXXX XX not skewed XXX XXX XXXXXXXX.(Leys, X., Ley, C., Klein, O., Bernard, P., &XXXXXX, X. 2013).
