Standard deviation is the measure of dispersion of the data around the mean. How closely or loosely is the data packed around the mean is indicated by the standard deviation. Clearly, larger the standard deviation, the more the data is dispersed. Therefore, it is highly desirable in research that the standard deviation should be low - the data thus collected is more reliable. Sample statistics are then used ...
