It facilitates comparison of two or more frequency distributions on the same graph. Category systolic bp (mmHg) Number of Persons Frequency polygon Frequency curve. The fourth module of this course focuses on the new bi semantic Model (bism and its implementation as a tabular model hosted by sql server 2012 Analysis Services (ssas) Tabular Mode. This 1 hour 20 minutes video includes discussions, such as: How should I build my bi semantic Model tabular project?, slides, diagrams, and an in-depth, 35 minute demo block, showing you key principles in 13 detailed, hi-res demonstrations, which you can select, interests follow, pause, and. At the heart of bi semantic Model is the freedom to power any analytical user experience by using any analytical data storage, and so breaking away from a traditional dependency of user tools on a specic analytical back-end. For example, drill-through and hierarchical advantages of multidimensional analysis used to require you to build and maintain cubes, a complex task. With bism, it is now, at last, possible to have the benets of multidimensional analysis using simpler, tabular, relational data. At the same time, you can use the newest, tabular tools such as ssrs power view, while still using traditional cubes.
Graphical Presentation of data Presenting data in the form of graphs paperless prepared on a graph. The graph has two axes: x y usually, independent variable is marked on the x-axis and dependent variable on the y-axis. Common Types: Histogram Frequency polygon Frequency curve histogram Histogram is a graph containing frequencies in the form of vertical rectangles. It is an area diagram It is the graphical presentation of frequency distribution. X-axis is marked with class intervals y-axis is marked with frequencies Histogram differs from bar diagram. The bar diagram is one dimensional, whereas histogram is two-dimensional. Uses of histogram It gives a clear picture of entire data It simplifies complex data median and mode can be calculated.
Tabular Presentation of Data, arranging values in columns is called tabulation. The amount of oxygen content in water samples. Water samples, amount of O2 in.188.8.131.52. Diagrammatic Presentation of data It is a visual form of presentation of statistical data in which data are presented in the form of diagrams such as bars, lines, circles, maps Advantages of diagrammatic presentation of data: It more attractive it simplify complex information It saves. Rules for drawing diagrams It should have a title Proper scaling should be used. Index must be given for better understanding of diagrams Common Types Line diagram pie diagram Bar diagram Line diagram. A traffic survey shows the following vehicles passing a particular bus stop during a hour Vehicles Frequency cars Lorries Motor Cycles Buses Total 76 pie diagram Example: blood group of 50 students Group Students A 5 B 20 ab 10 O 15 Bar diagram.

Frequency distribution is a statistical table containing groups of values according to the number of times a value occurs. The data collected by an investigator is called raw data. Raw data is ungrouped data. It is not in order. Raw data is arranged in order called array. The data arranged in ascending order or descending order. Frequency distribution with Classes, it is constructed with class intervals.
It is a frequency distribution of continuous series. Raw data arranged as plan array data. Then the data is divided in to groups called classes. The first class and the last class are fixed by seeing the lowest and highest values. Lowest and highest numbers of each class are called class limits (upper lower). The class limit may be made in two methods: Inclusive methods, exclusive method. Presentation of data, tabular presentation, diagrammatic Presentation, graphical Presentation.

Processing of data, the first step in processing of data is classification and tabulation. Classification is the process of arranging data on the basis of some common characteristics possessed by them.
Two approaches in analysing data are: Descriptive statistics, inferential statistics, descriptive statistics are concerned with describing the characteristics of frequency distributions. The common methods in descriptive analyses are: measures of central tendency. Measures of dispersion, tabulation, cross-tab, contingency table, line diagram, bar diagram, pie diagram. Histogram, frequency polygon, frequency curve. Quantile, q-q plot, scatterplot, the inferential statistics helps to decide whether the outcome of the study is a result of factors planned within design of the study or determined by chance. Common inferential statistical tests are: T-tests, chi-squire test, pearson correlation. Frequency distribution, simple depiction of all the data.

Having presentational information separate writing from the content of a web page or web site offers many direct benefits, including: Full control over several web pages or an entire web site by manipulating a single css style sheet.

Before css however, tables were often used to create the overall layout of a web page, menu links, or page elements. While switching from tables to css to lay a page out is obviously encouraged, i've seen quite a few developers confused to think that tables shouldn't be used at all. As a result, numerous ridiculous implementations and even tutorials for displaying tabular content in a tabular manner while "avoiding" tables have surfaced. Although using them for layout is semantically incorrect, tables still serve a purpose and remain an important part of the xhtml specification! Advantages of style that is separated from content.

While this is obviously better than deprecated html attributes, the style is still equally ingrained in the content. body div style"border:1px red" p style"font-family:verdana; color:red" some red text in verdana /p /div /body using css we can completely separate the style information from the content. The power of separating presentation from content starts to become apparent - every div and p element for example will acquire their style information from the css in the header. head style type"text/css" body background-color 000000; div border:1px red; p font-family:verdana; color:red; /style /head body div p some red text in the font verdana /p /div /body finally, by linking to an external.

Size, color, margins, borders - anything that relates to how the content appears, rather than what it actually consists of, falls within presentation. Css is a way for website designers developers to add style (colors, fonts, borders, margins, etc.) to web pages. Most importantly, however, css writing is a way for the designers/developers to keep style information separate from the actual content of a website. Css is perfect for custom website design projects. It is well known that css has long been the recommended way to add style to web pages. However, the philosophy behind separation of content and style - where the true power of css lies - often goes misunderstood and thus not taken advantage.

This post is an attempt to encourage proper css use for the separation of style and content by shedding light on what exactly separation of style and content means in the terms of css and the advantages it offers website designers, developers, and visitors. Distinguishing between presentation and content, the most common term for the design/development concept is "separation of presentation and content but what exactly is presentation as opposed to content? Content refers to the information as well as its structure. While structure may seem in between the two, presentation becomes meaningless without structure and thus structural elements such as a div, a class name, or an identifier must also belong for to the content. Presentation refers to anything related to how the "content" (or structure) is presented.
