DATA PRESENTATION





The data presentation is defined as a method by means of which the people summarize, organize and give the information by using a wide range of tools like figures, diagrams, pie charts, histograms and the graphs. The techniques which are used to represent the various mathematical data vary widely. Some common presentation modes include coding the data, analysis of data, drawing the various diagrams, boxplots, tables, histograms & pie charts.

Some better methods required for presenting the data vary depending upon the type of info, volume & complexity of data and audience. A feature called coding data is used to create various categories of info like gender, which is a mathematical equivalent. Coding data is basically used for present the non mathematical values like numbers through electronic modes. Such a type of data representation is most useful for mathematicians who need to enter information into the computer systems prior to analysis.

Stem & leaf diagrams are the most popular types of data presentation which is used to make a visual image of mathematical info which the mathematicians wish to convey. This info can include numbers which correspond to a human age or the date of birth. Frequency charts are the types of data representation utilised to organize and quantify data in a certain order depending upon the frequency of occurrence.

Bar graph: It is used in order to display a discrete data. These can be drawn horizontally or vertically. Each bar is required to be of the same width and same distance away.

Line graph: It is used to view continuous data for example, data collected over time. We can utilise it to show multiple datasets and has both the independent and dependent variables.

Scatter graph: They show whether there are correlations between two sets of data. Adding a line of best fit to these graphs is a good idea to show both positive and negative correlations where they exist.

Pie chart: Shows a quantity which can be divided into parts these can be placed on to maps to show variations in composition of geographical phenomenon.

Histogram:Similar to a bar graph, but used to present continuous data, e.g. precipitation data on a climate graph. Can be drawn horizontally or vertically. Each bar has to be the same width and the same distance apart. Maps are a great way to localize your data and make it seem relevant.
