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

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.

Major States in each stratum: -

1.East : West Bengal, Assam, Arunachal Pradesh,

Tripura, and Manipur.

1. Hostel (University of Pune, Pune)

2. National Youth Integration Camp

(Held at University of Pune, Pune)

3. Matrimonial Website www.shaadi.com

Normality Testing

  • Multiple Linear Regression
  • Trend Analysis
  • Prediction of the Tallest Indian

Statistical Analysis

  • Paired t-test
slide6

Conclusions

  • 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.

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.

slide8

Suggestions

  • 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.
