An ogive is another statistical tool primarily used for finding out different quartiles in a distribution. Tabular Presentation of data is a method of presentation of data. From such a device we can also identify the number of observations lying above or below a certain value of the concerned variable. Cartographers and geographers consider such maps as a very important cate Diagrams can present the data in an attractive style but still there is a method more reliable than this. 12.6 Meaning of Statistics 12.7 Need and Importance of Statistics 12.8 Importance of the Organisation of Data 12.9 Presentation of Data in a Sequence 12.10 Grouping and Tabulation of Data 12.1 1 Graphical Representation of Data 12.12 Types of Graphical Representation of Data 12.12.1 Histogram 12.12.2 Bar Diagram or Bar Graph The entire area in the circle is subdivided into a number of parts by several radii which are separately related to the total area of the circle and also maintain the same proportional relation with the angle at the centre. Semi-tabular Method Uses both textual and tabular methods. This method comprises presenting data with the help of a paragraph or a number of paragraphs. Histogram (4). Very helpful for various levels of Nepal Bank Limited. Scatter plots. Other-wise, it will represent various concave, convex or irregular curves when viewed from the origin. Basics of statistics. The sum of frequencies for all classes will always equal ? It allows us to present statistical data in an attractive manner as compared to tables. Objectives of Tabulation: a] Helps in understanding and interpreting the data easily. Here, the aggregate value of the variable is expressed as the total area of a circle with a reasonable radius. vey statistics are given; this work is reflected in the final chapter of Schmid (1983). Brief descriptions of some useful statistical plots are presented in the subsections below. Ogives (of both the types) drawn on the basis of the above data and determination of the median wage: Here, being the middle-most value of the given wage rates, the median wage is found OB (= Rs.

A graph is a sort of chart through which statistical data are represented in the form of lines or curves drawn across the coordinated points plotted on its surface. They can distinctly and attractively be displayed on a screen for presentation with various colourful lines. Introduction to Data Analysis and Graphical Presentation in Biostatistics with R Statistics in the Large. Two separate line diagrams showing fluctua­tions in the values of exports and imports of India during (1987—96) are shown below: In the diagram drawn above the successive years from the table are shown horizontally and the corresponding values of export and import are shown vertically and the points are located separately on the plane from the middle of the respective years and the lacus of those points exhibit the trend along the line diagrams. They include plots such as scatter plots, histograms, probability plots, spaghetti plots, residual plots, box plots, block plots and biplots. Since this method makes the data easier to understand, it has a lot of advantage in the field of Statistics.

We have chosen this horizontal bar diagram to facilitate comparison of perfor­mances of 5 organisations for the years 2011 and 2012, respectively. Two or more (but finite number of) line segments can also be drawn on the same quadrant when information on different variables over the same period or time are simultaneously represented using the same unit of measurement along the same axis. Statistical maps are of great interest both to cartographers and to statisti cians. Advantages thousand) of five organisations of India in the financial year 2011-12. This kind of a diagram is drawn for a fre­quency distribution of a continuous variable in terms of cumulative frequencies of both the types (more than or less than type). Component bar diagrams show number of labourers of different categories and their respec­tive percentages for the years 2000 and 2010. Tabulation – Orderly arrangement of data in rows and columns. Example : In 1999, out of a total of five thousand workers of a factory, four thousand and two hundred were members of a Trade Union. While tracing out such a diagram, the usual convention is to show the successive values of the variable under study along the vertical axis in an increasing order and the time dimension along the horizontal axis.

They can be used with both discrete and continuous data. The researcher should use a language in the presentation of data that is easy to understand and highlights the main points of the data findings. Graphical methods have played a central role in the development of statistical theory and practice. Graphical representation helps to quantify, sort and present data in a method that is understandable to a large variety of audience. We can thus draw a number of line- diagrams for different data series on the same quadrant. It is easy to understand and it is one of the most important learning strategies. Very helpful for various levels of Nepal Bank Limited. b] It helps in comparing data. These techniques are easy to do, but I’ve rarely (if ever) seen them all demonstrated so well in a single talk.

It allows the viewer to compare data relating to two different time-periods or regions. PRESENTATION OF DATA This refers to the organization of data into tables, graphs or charts, so that logical and statistical conclusions can be derived from the collected measurements. Clearly there is much overlap of the area of graphical data analysis and the area of graphical data presentation, but there are many special considerations that arise when a graph is made to present data to others. Data Presentation. Pie Diagrams. TEXTUAL PRESENTATION - The data gathered are presented in paragraph form. The three main forms of presentation of data are: 1. 3. Table 7.8(A): Educational Expenditure in the Last Five-year Economic Plan: Let us first convert the given data into respective percentages and then into the required angles to be shown at the centre in two more co­lumns and represent them in the following way: Here, angle at the Centre = Percentage x 3.6. Presenting data. Data can be presented in one of the three forms: text, tables, and/or graphs. It is another well-known useful statistical weapon to represent raw data decently. Tabulation – Orderly arrangement of data in rows and columns. It should carefully be noted that none of the two axes be too long or too short with respect to each other. Tables are commonly used, and there are many graphical and numerical methods as well. These diagrams are used in a situation where two or more related categories are to be compared simultaneously. 3. A method of data presentation in which data are represented by bars of equal width, the height / length of the bar corresponding to the value of the data. Graphical methods have played a central role in the development of statistical theory and practice. One cannot expect to get liner data from a pie chart, thus basic knowledge and application of different type of presentation methods saves time. It represents the set of data in a meaningful way. It is a systematic and logical arrangement of data in the form of Rows and Columns with respect to the characteristics of data. and they are really and surely capable of depicting some important features of the data which they individually are not able to exhibit. Further, graphs of statistical data clearly bring out the relative importance of different figures, the trend or tendency of the values of the variables involved can be studied too. 5. ADVERTISEMENTS: The following points highlight the three main techniques and methods used for representing data graphically. The appropriate type of representation for a collection of data depends in part on the nature of the data, such as whether the data are numerical or nonnumerical.
