What is Statistics? Statistics is the science concerned with developing and studying methods for collecting, analyzing, interpreting and presenting empirical data . Statistics is a highly interdisciplinary field; research in statistics finds applicability in virtually all scientific fields and research questions in the various scientific fields motivate the development of new statistical methods and theory. In developing methods and studying the theory that underlies the methods statisticians draw on a variety of mathematical and computational tools. Types of Graphs  In statistics, we generally come across with vast sets of data. Just to recall that statistics is a science of numbers that is concerned with collection, organization, measurement, and analysis of the numerical data. It usually deals with the quantity more than quality. Sometimes, it becomes really hectic to work with a large amount of data. There are tedious and lengthy calculations in statistics. It is easier to draw...

Geometric shapes of different sizes can be seen everywhere; in nature as well as in man-made structures. Men work with these geometric shapes in a variety of fields. There is geometry in art, sculpture, engineering, architecture, and many other fields. Recognition and knowledge of geometric properties help develop logical thinking and problem solving skills. Clearly, you need to study geometry to better understand and appreciate the things around you. Listed below are terms and definition in geometry. Geometry - branch of mathematics that deals with points, lines, planes and solids and examines their properties.  Point – has no size; length, width, or height. It is represented by a dot and named by a capital letter. Line – set of points which has infinite length but no width or height. A line is named by a lower case letter or by any two points on the line. Plane – set of points that has infinite length and width but no height. We name a plane with a capital letter. Space – set of ...

By now, you are already familiar with  algebraic expressions . The expression  x  and  x+3  are algebraic expressions. In expressions,  w  is a  variable . Variables may be used to represent patterns in expressions. Suppose that in a certain rectangle, the length is 3 inches more than the width. There are possible values for the length and width as shown in the table below.    Width     Length     3    3+3 or 6     5    5+3 or 8     7    7+3 or 10     w     w+3 Can you see the pattern? From the table above, the pattern that exists between the width and the length is summarized by the algebraic expressions w and w+3, respectively. That is the length, the length of the rectangle is 3 inches more than its width. Mathematical symbols and its meaning Many words and phrases suggest mathematical operations . The follow...

Origin and Growth of Statistics: The word ‘ Statistics’ and ‘ Statistical’ are all derived from the Latin word Status, means a political state.  The theory of statistics as a distinct branch of scientific method is of comparatively recent growth. Research particularly into the mathematical theory of statistics is rapidly proceeding and fresh discoveries are being made all over the world. Statistics is concerned with scientific methods for collecting, organising, summarizing, presenting and analyzing data as well as deriving valid conclusions and making reasonable decisions on the basis of this analysis. Statistics is concerned with the systematic collection of numerical data and its interpretation. What are the two major types of statistics ?  The two major types of statistics are descriptive statistics and inferential statistics. Each of these statistical segments serves specific purposes, and they are used to accomplish different objectives Statistics is not a mere device fo...
