This project presents a comprehensive analysis of newborns' birth weights recorded on December 18, 1997, at Mater Mothers’ Hospital in Brisbane, Australia. The study focuses on the statistical examination of birth weights based on gender and time of birth.
The goal of this project was to get familiar with these practices:
- Descriptive Statistics,
- Goodness-of-Fit Tests: Evaluation of various statistical distributions to fit the birth data.
- Hypothesis Testing: Tests conducted to analyze the dependence of birth weight on gender and time of birth (chi-squared Goodness-of-fit, t-test, Lilleforse's test) on real data.
It contains MATLAB scripts for performing statistical tests and generating images that are discussed and displayed in the final report english-version.pdf.
All the generated images are saved in the directory images. It is usually not a good practice to upload images to github.
The original data is saved in deti.dat. The description of the data is the following:
- NAME: Time of Birth, Sex, and Birth Weight of 44 Babies
- TYPE: Observational
- SIZE: 44 observations, 4 variables
The dataset contains the time of birth, sex, and birth weight for each of 44 babies born in one 24-hour period at a Brisbane, Australia, hospital. Also included is the number of minutes since midnight for each birth.
The data appeared in the Brisbane newspaper The Sunday Mail on December 21, 1997.
- Columns
- 1 - 8 Time of birth recorded on the 24-hour clock
- 9 - 16 Sex of the child (1 = girl, 2 = boy)
- 17 - 24 Birth weight in grams
- 25 - 32 Number of minutes after midnight of each birth
Values are aligned and delimited by blanks. There are no missing values.
Forty-four babies -- a new record -- were born in one 24-hour period at the Mater Mothers' Hospital in Brisbane, Queensland, Australia, on December 18, 1997. For each of the 44 babies, The Sunday Mail recorded the time of birth, the sex of the child, and the birth weight in grams.
