grouped data for Statistical Measure for
Shampoo in Indian market
In statistics and data analysis, the mean, median, mode, range, and standard
deviation tell researchers how the data is distributed. Each of the five measures
can be calculated with simple arithmetic formulae. The mean and median
indicate the "centre" of the data points. The mode is the value or values that
occur most frequently. Range is the span between the smallest value and largest
value. Standard deviation measures how far the data "deviates" from the centre,
on average. Knowing how to calculate these statistical measures will help you
analyze data from surveys.
We have conducted survey on sample of 50 people age group between 18-25,
who are consumers of various Shampoos. We compare Sunsilk, L’Oreal with
respect to other brands on various factors. In questionnaire, we compare various
shampoos on 10 features such as price, size, aroma etc. For which we have got

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.
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.
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.
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
Standard deviation (σ) =
The quartiles of a set of values are the three points that divide the data set into
four equal groups, each representing a fourth of the population being sampled
For group data the formula is:
Q1 can be given as (L+ n/4 – pcf x i )/f
Q3can be given as (L+3 n/4 – pcf x i )/f
In descriptive statistics, the Inter-quartile Deviation, also called the midspread or middle fifty, is a measure of statistical dispersion, being equal to the
difference between the upper and lower quartiles.
Inter-quartile Deviation = Q3 − Q1
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. Qualitatively, a negative skew indicates
that the tail on the left side of the probability density function
is longer than the right side and the bulk of the valueslie to the right
of the mean. A positive skew indicates that the tail on the right side
is longer than the left side and the bulk of the values lie to the left of
the mean. A zero value indicates that the values are relatively evenly
distributed on both sides of the mean, typically implying a symmetric
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

Promoting the shampoo brands poses another challenge for the marketers,
resulting in high adv. spends and media spends. Sunsilk spent 8 crores on
advertising on TV in the first four months of its launch. HLL’s estimated
advertising expenditure for each new shampoo launch was between Rs.4 crores
and 6 crores in the introductory phase. The ad-to - sales ratio of the companies
have shown remarkable jump from 10 % to 20 % compared to the average of 5
% for most product categories.
One of the biggest barriers to shampoo usage is the consumer perception that it
harms the hair. Thus companies are focusing on defending the product against
accusations by promoting the strength, nourishment and beauty of the hair ‘The 3 - in -1 Capsule ‘for ultimate hair. Companies are still associating it with
modern life styles to find acceptance in semi - urban and rural non-users to
build and enlarge shampoo usage levels. Thus companies will have to mould
new consumer usage patterns to its own benefit, to have a competitive
advantage and stay out there in the longer run with a respectable market share.
A market segment consists of a large identifiable group within a market. A
company that practices segment marketing recognizes that buyers differ in their
wants, purchasing power, geographical locations, buying attitudes, and buying
habits. Because buyers have unique needs and wants, each buyer is potentially a
separate market. Ideally, then, a seller might design a separate marketing
program for each buyer, though no company is willing to customize its offer
communication bundle to each individual customer. The company instead tries
to isolate some broad segments that make up a market.
Two broad groups of variables are used to segment consumer markets. Some
researchers try to form segments by looking at consumer responses to benefits
sought, use occasions or brands. Other researchers try to form segments by
looking at consumer characteristics. They commonly use Geographic,
Demographic or Psychographic characteristics.
