  14. 14. Mean, Mode and Median • Mean: The arithmetic mean or average of a set of numbers is the expected value. The mean is calculated by adding up all the values, and then dividing that sum by the number of values. • Mean (x)=A+(Σ(fd)/n)*i • Median: The median is the middle value in a set of values. To find the median, order the numbers from largest to smallest, and then choose the value in the middle. • Median =L+((n/2-PCF)/f)*i • Mode: The mode of a set is the value or values that occur most frequently. There can be more than one mode in a set. If there is more than one mode, you simply list all of the modes; you do not have to average them. • Mode=L+{∆1/(∆1+ ∆2)}*i Renzil D’cruz http://RenzilDe.com http://about.me/renzilde http://linkedin.com/in/renzilde

  16. 16. Standard Deviation: • It is a measure of how much spread or variability is present in the sample. If all the number in the sample are very close to each other in such cases SD is zero (0) and if the numbers are well dispersed than SD tends to be large. It is calculated as • Standard deviation (σ) = *i S.D 15 10 S.D 5 0 SUNSILK LO'REAL OTHERS
  17. 17. Skewness: • It is a measure of the asymmetry of the probability distribution of a real-valued random variable. The skewness value can be positive or negative, or even undefined. SKEWNESS 0.1 0.05 0 -0.05 -0.1 -0.15 -0.2 -0.25 SUNSILK LO'REAL OTHERS SKEWNESS
  18. 18. Coefficient of quartile deviation: • It is the simple method of studying variation. it is defined as the difference between the value of the smallest and the highest observation. the relative measure corresponding to deviation is called coefficient of quartile deviation t is given by, • Coefficient of quartile deviation =(Q3 − Q1)/( Q3 + Q1) Coefficient of quartile deviation: 0.3 0.2 Coefficient of quartile deviation: 0.1 0 SUNSILK LO'REAL OTHERS

  23. 23. Carl Pearson correlation coefficient • the Pearson product-moment correlation coefficient (sometimes referred to as the PPMCC or PCC, or Pearson's r, and is typically denoted by r) is a measure of the correlation (linear dependence) between two variables X and Y, giving a value between +1 and −1 inclusive. It is widely used in the sciences as a measure of the strength of linear dependence between two variables.
  24. 24. • The interpretation of a correlation coefficient depends on the context and purposes. A correlation of 0.9 may be very low if one is verifying a physical law using high-quality instruments, but may be regarded as very high in the social sciences where there may be a greater contribution from complicating factors. • CorrelationNegativePositive • None−0.09 to 0.00.0 to 0.09 • Small−0.3 to −0.10.1 to 0.3 • Medium−0.5 to −0.30.3 to 0.5 • Strong−1.0 to −0.50.5 to 1.0 Renzil D’cruz http://RenzilDe.com http://about.me/renzilde http://linkedin.com/in/renzilde
