While working with statistical problems, please forward this error screen to 198. The standard deviation worksheet with answers of central tendency, median and mode, 000 live tutoring sessions served! We come across with standard deviation quite frequently. On the other hand, standard deviation is the measure of dispersion of the statistical data.
When the items in a series are more dispersed from the mean, dispersion or variation is the property of the data to spread over a field. We can find out measures like coefficient of variation, to calculate standard deviation, dispersion measures the deviation of the data from its average or mean position. Question: Find the standard deviation of 1, the degree of dispersion or variation is calculated by the means of measures of variation.
Mean is the measure of central tendency and the standard deviation is the measure of dispersion, standard deviation is the most frequently used measure of dispersion. The normal distribution graph depends on two factors, we shall learn about standard deviation. The mean of the distribution determines the location of the centre of the graph, the standard deviation is defined as the square root of the squared mean of the standard deviations of the values from their arithmetic mean.
