Abstract





Objective:
The aim of the study was to explain circular statistics and hypothesis tests
with life science data. The accuracy of the statistical method used in scientific
research is related to the data structure and scale type. Therefore, scale
types and data structures should be well defined. It is possible to
frequently come across circular data in many different scientific fields such
as medicine, biology and physics. These data are usually obtained by compass
or clock. Compass; the flight direction of any animal that is released, the
direction of the wind or the direction of current in the ocean, clock; the
birth time of infants, the time of crisis, circadian rhythms or biological
rhythms can be shown as examples. Apart from the clock, such data may also be
obtained by a scale that expresses a time such as day, month and year.


Material and Methods: The data related to 179 normal deliveries that took place in
Yüzüncü Yıl University Medical Faculty Hospital in 2008 were used. Circular
data analysis was performed using the NCSS2007 statistical package program.


Results: The
times of birth of infants show a uniform distribution. No significant
difference at a significance level of 5% was found between the times of birth
according to gender.


Conclusion: It
has been stated that circular data cannot be analyzed by the analysis methods
developed for linear data due to several reasons. If circular data are
analyzed by linear statistical methods, inaccurate or nonsense results
usually emerge. Therefore, it was emphasized that appropriate statistical
methods should be used.
