Measures of dispersion
-
Standard deviation is the average distance of each score from the mean (i.e. the variation in the data)
Lower standard deviation = data points tend to be very close to the mean i.e. all participants responded in a similar way
Higher standard deviation = the greater the spread of data. Not all participants were affected by the IV in the same way
