TITLE:

CIRCULAR STATISTICS: A DIRECTIONAL STUDY, VIA GEOGRAPHIC COORDINATES, OF APPROVED STUDENTS IN THE PREPARATORY SCHOOL OF AIR CADETS

KEY WORDS:

Directional average; Circular standard deviation; Trigonometric functions; Circular boxplot

PAGES: 48
BIG AREA: Ciências Exatas e da Terra
AREA: Probabilidade e Estatística
SUMMARY:

Circular statistics has applications in several areas whose data are measured in directions, angles or have periodic behavior, such as: direction of migration of animals, winds or geological materials, times of peak traffic or insect birth, in addition to geographic coordinates among others. However, in our daily lives, we can instinctively evaluate, in a wrong way, data with angular characteristics in a classical way, using linear descriptive statistics. Thus, the objective of this work was to study the theory of circular statistics and compare the results between linear descriptive statistics, that is, used for data on the real line, contemplated in regular education, and circular statistics, evidencing the importance of studying the latter for data angular and circular graphs, with the aid of the R software. For the application of the theory, a set of real data of the geographic coordinates of the hometowns of students from the Preparatory School for Air Cadets (EPCAR) was used, comparing the statistical measures of three different years of entry, obtaining in each case mean, median and circular variance, in addition to the construction of a circular boxplot and Rayleigh test.
