The median is thevalues that occupies the middle position and it referred to as measure of locations. The mediandivided the frequency distribution exactly into two halves. The mode is defined as the value thatoccurs most frequently in the data. It only measures the central tendency that can be used for datameasure in nominal scale. The mean and median was easy to compute and comprehend the data.It can be determined for ordinal scale, interval and ratio.Measures of VariabilityTo measures the variability by determine the below aspects.Range (including IQR & SIQR)Mean Deviation ("BA201 Sampling Distributions: Excel And Equations")VarianceStandard DeviationConfidence Interval for meanTo determine the above aspects by using the below steps,4
