Ilmu Statistika

Statistika (Statistics) : Ilmu yang antara lain mempelajari cara-cara menetukan suatu penduga bagi suatu parameter, serta kemudian bertugas mengambil kesimpulan mengenai nilai parameter tersebut berasarkan nilai penduga yang didapat. (Andi Hakim, Rambe, 1993)

Statistika : Metode, ilmu dan atau seni yang berkaitan dengan tata cara pengumpulan data, analisis data, interpretasi hasil analisis untuk disimpulkan serta pelaksanaan perkiraan pada batas-batas yang masih dibenarkan. (Solimun, 1997)

Menurut Torrie (1993) Statistika adalah ilmu pengetahuan murni dan terapan, mengenai penciptaan, pengembangan dan penerapan teknik-teknik sedemikian rupa sehingga ketidakpastian inferesia induktif dapat dievaluasi (diperhitungkan)

Statistika adalah ilmu pengetahuan yang mempelajari metode yang paling efisien tentang cara‑cara pengumpulan, pengola­han, penyajian serta analisis data, penarikan kesimpulan serta pembuatan keputusan yang cukup beralasan berdasarkan data dan analisa yang dilakukan.

Sedangkan Statistik (Statistic) adalah nilai yang didapat dari sampel yang diambil yang digunakan untuk menduga nilai dari populasi (Parameter) dimana sampel tersebut diambil. Menurut Undang-Undang Statistik Republik Indonesia (1997) statistik adalah data yang diperoleh dengan cara pengumpulan, pengolahan, penyajian dan analisis serta sebagai sistem yang mengatur keterkaitan antarunsur dalam penyelenggaraan statistik.

A Sample of MOTIVATION STATEMENT for Master Scholarship

Berikut contoh motivation statement yang pernah saya buat.

Semoga bermanfaat.

MOTIVATION STATEMENT

Since I was in Senior High School, I have believed that mathematics is an important factor in a life. All human activities in several fields such as information technology, economics, physics, social and others will run well if they are cited in a good mathematics framework. This circumstance stimulated me to attend faculty of mathematics and natural science. I choose statistics as my specialization even though at this time, there weren’t many people know about statistics and few students choose statistics as their specialization. I saw in several developed countries such as The Netherlands and Belgium, the mathematics degree-holders not only have many opportunities but also were cited as important scholar in their societies.

As a student at XXXX Department faculty of XXX of XXX University, I had numerous opportunities to do many activities. From XXX to XXX I had chances to become a lecturer assistant in mathematics and statistics laboratory. My resposibilities are taught and supervised students in the following subjects; Basic Programming, Computational Statistics, Statistical Methods and XXX.

Besides studying, I was active in the student senate and became the head of research and development division. In XXX I, in a team, became the third winner of Indonesian student research competition. Overall I am pleased with my academic record and I believe that it has prepared me very well for graduate school.

Presently, I work as a XXX for XXX. My responsibilities are teaching, conducting research individually or in a team and etc (mention your responsibilities)…… Working as a statistics lecturer needs deep knowledge of fundamental mathematics and experiences in advanced research of applied statistics. Even though my undergraduate programme has given me a strong background in the fundamentals of various mathematics especially statistics, this is not enough for me to be a professional lecturer. I have to continue my study to enrich my skills and broaden my knowledge.

Currently, our institution which one of the functions is to XXXX to the government of Indonesia, has formulated its Long Term Plan known as the XXX PLAN, which directed toward the establishment of the Integrated National XXX System. This plan is including the development of statistics in various fields such as economy, demography, agriculture, and health. It leads the need of statistician who expert in those fields. Today, there is no Master of Science in XXX in our institution. These circumstances persuade me to apply Master of Science in XXX under XXX Scholarship programme.

Master of Science in XXX is needed in Indonesia because of the following reasons:

1. It will improve education in XXX and Indonesia in general, and strenghten the establishment of the Integrated National System
2. I will fill the masters of XXX scarcity and strengthen the sustainable development of Indonesia.

Considering all factors above. I believe that the chosen study will benefit Indonesia in general

I consider myself to be a good candidate for XXX Scholarship because I am young, energetic, hardworking, visionary, and motivated person who believes that I can do something for the benefit of my country to whom I have been working. I did my best with all maximum efforts I could give for my institution. But this is not enough. Frankly, I am not satisfied yet with what I did. I believe that I can do much better if I am trained and developed through a master of science in Belgium.

Discriminant Analysis

The aim of discriminant analysis is to find a set of independent variables that predict membership of groups. It is a technique for classifying a set of observations into predefined categories. A prediction of a new observation to a category is then made possible.

Applying Discriminant Analysis, provide us with linear combinations of the original values. These new values give us the maximal separation between the groups of interest and are therefore better in showing us the differences across the groups of interest. Classification error rates can also be obtained to assess the performance of the derived discrimination functions.
