Statistics is a form of mathematical analysis that uses quantified models and representations for a given set of experimental data or real-life studies. Introduction. 0000018548 00000 n Let's jump right in. Descriptive statistics are the simplest type and involves taking the findings collected for sample data and organising, summarising and reporting these results. • Have a working knowledge of accuracy, precision, and significant digits, and recognize the importance of dimensional … 2- drawing of inferences about a body of data when only a part of the data is observed. Completing this unit should take you approximately 22 hours. From a high-level view, statistics is the use of mathematics to perform technical analysis of data. endstream endobj 118 0 obj << /Type /FontDescriptor /Ascent 1000 /CapHeight 0 /Descent -206 /Flags 4 /FontBBox [ -600 -208 1338 1034 ] /FontName /KOCPDD+Tahoma /ItalicAngle 0 /StemV 0 /FontFile2 119 0 R >> endobj 119 0 obj << /Filter /FlateDecode /Length 16375 /Length1 28936 >> stream Introduction to Statistics and Basic Concepts slides.pdf from EDMS 451 at University of Maryland, College Park. A population is a well-defined set of similar items with certain characteristics that are of interest to the observers. In Chapter one, we introduce the basic concepts in statistics. >$99��ǰ�g�%����FgbO��=�vG��]�[��/IV��Ju���Y�Q�z[A����Ae$�{�Q�M梌� J^��B�����ɝ//[�@�n��@]��F�����n��z_���I���G8���ș���i�׭��B����w8�a�f����,P?���+���P�k�GE��z�l�qbmqbp��1ѯe��j#P����o�V8�BN���,�6�أ:=���/Nv���_fD˼�mO�D�6���`"'��*�������⫦fU�#_X���/�,-�c��UXR����[�nKJ��*D1h#�4��1��vS��{���܌"\uj�^���f�l [�H�4�����{}Y�Duj� Course Hero, Inc.

All the elements we will perform in the study are called population. – any characteristic possessed by a set of objects (e.g., people) of interest, but that only has one value, or otherwise believe that might affect other variables. This aspect can be finite or infinite. Basic statistics presentation 1. Therefore, the size of the population is the number of items it contains. This is the first of a six-part series of articles intended to provide the reader with a basic, yet fundamental knowledge of common biomedical statistical methods. Define and distinguish between population parameters and sample statistics. We now briefly define some key terms. Using a truly accessible and reader-friendly approach, this comprehensive introduction to statistics redefines the way statistics can be taught and learned. Importance of Statistics and Understanding Basic Concepts 4 lectures • 42min. Statistics is a field of study concerned with 1- collection, organization, summarization and analysis of data. This quick quiz features eleven basic questions of the topic. In many cases this will be all the information required for a research report. That is, you must establish or adopt a system of assigning values, most often numbers, to the objects or concepts that are central to the problem under study. 0000001172 00000 n 0000001472 00000 n Chapter two is devoted for organizing and graphing data set, and Chapter three is about numerical descriptive measure. View 1. Ԓ�R�R�Go�b`� Inferential statistics can be used to generalize the findings from sample data to a broader population. The most fundamental branch of statistics is descrip- tive statistics,that is, statistics used to summarize or describe a set of observations. • Model engineering problems and solve them in a systematic manner. Basic Concepts of Measurement Before you can use statistics to analyze a problem, you must convert the basic materials of the problem to data.
