INTRODUCTION
The report is based on analysis of Data from the National Infant Development Survey, which
tracks a group of people raised in a particular week in 1958, was obtained at 3-5 year intervals
(Wang, Hastie & Owen, 2017). In order to do proper analysis of such aspects a range of SPSS
tests have been applied to assess whether there is suitable relation among variables or there is
any significant outcome that can derived from data set of 50 respondents containing male and
female.
I HYPOTHESIS AND METHODOLOGY
Descriptive data and binary logistic regression will be checked to examine the association
between BMI at 7 and 50 years of age. Models are evaluated independently with or without
response variable. The observations shall be recorded and viewed both verbosely and where
necessary, socially. We would test the following assumptions:
H1: There is significant relation between Body mass index at age of 7 and at age of 50.
H0: There is no significant relation between Body mass index at age of 7 and at age of 50.
H1: The adiposity at age 50 is measured as body mass index (BMI), is associated with own
education, father’s education and sex.
H0: The adiposity at age 50 is not measured as body mass index (BMI), is associated with own
education, father’s education and sex
Measures and variables:
Respondent’s sex- In the report this has been indicated by different aspects as 1 indicates to male
and 2 refers to female respondents.

Father left school at minimum age or not- This has been presented by two variables which are
one and two. Herein, 1 refers to Father left school at minimum age and 2 refers to Father has not
left school at minimum age.
Number of O-levels passed by 1974- In order to do so, two variables are chosen which are one
and two. Herein one equals to O-levels passed by 1974 and 2 equals to O-levels not passed by
1974.
Physical functioning score- Herein, 1 refers to excellent, 2 refers to good, 3 refers to average, 4
relates to poor and 5 relates to risky.
Emotional well-being score- Herein, 1 refers to excellent, 2 refers to good, 3 refers to average, 4
relates to poor and 5 relates to risky.
Social functioning score- Herein, 1 refers to excellent, 2 refers to good, 3 refers to average, 4
relates to poor and 5 relates to risky.
Social functioning score- Herein, 1 refers to excellent, 2 refers to good, 3 refers to average, 4
relates to poor and 5 relates to risky.
