Aim: - To check whether Indians are getting taller and to predict the height of the tallest Indian (Male/Female) in 2020.

Formulation of the problem

1. Paired t-test

2. Trend Analysis

3. Prediction of the Tallest Indian

Major States in each stratum: -1. East : West Bengal, Assam, Arunachal Pradesh,

Tripura, and Manipur.

2. West : Maharashtra, Gujarat and Rajasthan.

3. North : Jammu & Kashmir, Himachal Pradesh, Punjab,

Haryana and U.P.

4. South : Kerala, Tamilnadu, Karnataka and Andhra Pradesh.

5. Center : Madhya Pradesh, Bihar, Orissa and Chhatisgarh

Sampling Technique Population is all the Indians aged from 20-30 years.

Divide it into 5 strata namely East, West, North, South & Center.

Used stratified sampling with proportional allocation.

Conclusions1. Indians are getting taller.

2. Predicted average height in year 2020  (a) Male: 176.83 cms, Female:

163.81 cms (From Matrimonial Data)  (b)  Male: 172.17 cms,

Female: 161.34 cms (From Regression

Analysis) (c)  Male: 172.06 cms, Female:

162.22 cms (Generation wise)3. Predicted height of the tallest Indian in

year 2020 will be 195.58 cms.4. Generation wise average rate of increase

in height 4.1 Male (a)  Grand Father to Father:

1.49 cms. (b) Father to Male Child:

1.93 cms. 4.2 Female (a)   Grand Mother to Mother:

1.79 cms. (b)   Mother to Female Child:

1.95 cms.

Limitation

1. Data collection is done by distributing questionnaire (Anthropometrical measurements on height are not taken).

2. Sample size (a)   From Questionnaire Male: 136 Female: 55 (b) From Matrimonial website www.shaadi.com

Male: 840 Female: 840

3. Due to less data from matrimonial website www.shaadi.com (of 21 years), we are unable to detect cyclic variation in Time Series Analysis.

Suggestions

1.Prediction can be better if sample

size is increased along with

increase in no. of generations.

2. If data on tallest persons are

collected,

better prediction can be made

for the

tallest person in future.
