The purpose of the study is to define the gestational age as term or preterm depending on gestational week, as determined by the last menstrual period and ultrasound.
The statistical information were gathered from medical records of a clinic, it is uncertain the determination of gestational age through ultrasound was indicated and who measured date or obtained medical record report, it is very pertinent to know who obtained the data report and its preciseness and correctness of information is important.
QUANTATIVE ANALYSIS
Ickovics et al 2003 utilize both descriptive and inferential statistics to scrutinize the data, the reason for the study was to evaluate the difference among the two groups, for the inferential statistics the McNemar test was used, which was suitable for the degree of enquiry due to the matched group, the Cohort design was also implemented as they intended to quantify between groups. Also as relates to the variables outcome. (Polit & Beck 2008). The paired T test was also proper for the study due to the fact its purpose is to test the differences among the two groups that are either paired or matched on the essence of the characteristics.
The F test was also implemented, it occurs as the test used when apply multiple linear regression as this F statistics has been utilized while stipulating the influence between birth weight and preterm delivery (p1054). The purpose of linear regression is to describe the amount of the outcome variable is distinct to the independent variable (Burns & Groove, 2007)
Descriptive statistics were used by the author to relate the dispensing of the statistical data among topics such as age, race, and parity, they also possess illustrative analysis to explain the issues of statistical variables among the distributing of outcomes variables among the specimens.
