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

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) =

• 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

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.
• 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
