Mean, median, mode, Standard deviation for grouped data for Statistical Measure for Shampoo in Indian market

  1. 1. Managerial Statics Mean, median, mode, Standard deviation for grouped data for Statistical Measure for Shampoo in Indian market Presented to Sameer Virani By Renzil D’cruz http://RenzilDe.com http://about.me/renzilde http://linkedin.com/in/renzilde 1
  2. 2. Managerial Statics Introduction 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 good response from our Classmates, friends and family members. The shampoo market in India is estimated to be 2,500-3,000 crore. The shampoo market is India is categorized according to the benefits they provide. Mostly consisting of three kinds of shampoos cosmetic, herbal and anti dandruff, the shampoo market in India has managed to tap users of the various segments according to their requirements and preferences. Due to the continuous efforts of the top shampoo brands in India penetration of shampoos in urban areas is almost 100%. As far as penetration of shampoo in the rural areas is concerned it has risen by almost 18% in the current scenario. The top shampoo brands in India include Sunsilk, Clinic Plus, L’oreal and Pantene. The company that leads the shampoo market in India is Hindustan Unilever Limited. The top three most sought after brands Sunsilk, Dove and Clinic are produced by HUL. The company holds a 44% market share in the Indian shampoo industry. It is said that HUL earns almost 8% of its revenue from the sale of these products. Proctor and Gamble the second top shampoo brand in India holds a market share of around 25% in the Indian shampoo industry. The revenue earned from the value of shampoos from Proctor and gamble is almost 17%. 2
  3. 3. Managerial Statics Various Shampoos in Indian Market: Sunsilk: Sunsilk is a hair care brand, primarily aimed at women, produced by the Unilever group, which is now considered the world's leading company in hair conditioning and the second largest in shampoo.

  9. 9. Managerial Statics 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 60 50 40 Mean 30 Median Mode 20 10 0 Sunsilk L'Oreal Other 9
  10. 10. Managerial Statics 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 STANDARD DEVIATION 16 14 12 10 8 6 4 2 0 SUNSILK LO'REAL OTHERS Quartile: 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 Inter-quartile Deviation: 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 10
  11. 11. Managerial Statics 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. 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 distribution.

  15. 15. Managerial Statics FLEX 0.7 OTHERS 28.6 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 15
