Standard Deviation


	Standard Deviation
	Advantages Shows how much data is clustered around a mean value It gives a more accurate idea of how the data is distributed Not as affected by extreme values	Disadvantages It doesn't give you the full range of the data It can be hard to calculate Only used with data where an independent variable is plotted against the frequency of it Assumes a normal distribution pattern
	Evaluation The higher the calculated value the more the data is spread out from the mean. Parametric test.
