There are various methods of data representation like arrangement of data in tabulated form or in form of graphs or charts or maps or diagrams .These data representation methods described in grade XI of Andhra Pradesh sample papers are dependent on the nature of the data or nature of the analysis that is based on the data or others equal to it .We can understand each information that are having the same identical structure or having the same identification number. So anyone can easily find the data or value according to these specifications. We can take an example of GIS data that is used to represent the real objects as roads, trees, houses etc.
So data representation is a technique of capturing the raw data change them into the useful information and then represent them into the pictorial form or in tabular form. There are several methods like image processing , Global positioning system all are based on the various type of data representation .The main motive behind presenting the data is to understand the available data and deriving the meaning and also extract the useful in conclusion .The representation of data can be done in many ways like :
Statistical tables
or by rank order
or by frequency order .
These forms are useful in statistical analysis of the data .Initially all the data collect in scattered form but later it organize and change into the numerical facts. (Improve your skills by playing data analysis worksheets)
Statistical tables: Data will arrange into the form of rows and columns. These tables are used to collect the raw data and also the percentage or mean or median and so on.
Rank Order: Data is present in ascending and descending order .On the basis of rank or position order will be exhibit .as an example
S.NO. Scores S.NO. Scores
1 20 3 18
2 19 4 14
Frequency Distribution: Sometimes Rank order not much useful to summarize the series of raw data and also not describe about the frequency so in that case frequency table is used and range can also be described in it.
In upcoming posts we will discuss about Statistical experiments and triangle inequality theorem. Visit our website for information on z score chart
