Abstract: Relationship and simple analysis between two any circular variables are the main focus of this paper. Correlation measure, linear relationship and estimation of concentration parameters are some examples of simple approach in analyzing two circular variables. These analyses could be extended to the graphical plots to give a better understanding. A plot called “Spoke plot” which have been developed in MATLAB environments have been proposed to achieve this objective. As an illustration, the application of “Spoke plot” as a simple analysis between two circular variables using graphical plots in investigating the correlation, linear relationship and estimating concentration parameters are given using the Malaysian wind direction data.
Description: The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
