Introduction
Information design is a field that studies the way information should be displayed, which is based on the nature of the information that is being presented, and the way humans perceive that information. For instance, the data may provide a lot of information, but in order for us to understand it, it should be presented in a simple and clear way. Information design includes more than data visualization, for example, the design of indoor navigation in a mall.
listed below some principles that can help display any type of information:
Directions
Pick three principles. Explain the three principles selected and explain how you understand the meaning of each principle, and what it would mean for visualization practitioners. Find examples of business data visualizations to illustrate each of the selected principles. Explain how the examples illustrate the principle.
The three principles which are picked:
1.Show the data
2.Serve a reasonably clear purpose: description, exploration, tabulation, or decoration
3.Reveal the data at several levels of detail, from a broad overview to the fine structure
Explanation:;
1.Show the data:
Showing the data in different formats plays major role in describing the ideas.Various ways of showing the data are
1.Graphical representation
2.Excel
3.Symbolic Representation
4.In form of instructions/ Guidelines
2.Serve a reasonably clear purpose: description, exploration, tabulation, or decoration
The data defined form of description than in single word is the best way to define the data.The data representation in tabulation is more understandable.
Tabulation is a systematic & logical presentation of numeric data in rows and columns, to facilitate comparison and statistical analysis. It facilitates comparison by bringing related information close to each other and helps in further statistical analysis and interpretation.
To put it in other words, the method of placing organised data into a tabular form is called as tabulation. It may be complex, double or simple depending upon the nature of categorisation.

5 Major Objectives Of Tabulation:
(1) To Simplify the Complex Data
(2) To Bring Out Essential Features of the Data
(3) To Facilitate Comparison
(4) To Facilitate Statistical Analysis
Describing and documenting data is essential in ensuring that the researcher, and others who may need to use the data, can make sense of the data and understand the processes that have been followed in the collection, processing, and analysis of the data.
Research data is any physical and/or digital materials that are collected, observed, or created in research activity for purposes of analysis to produce original research results or creative works.
Research data can be generated for different purposes and through different processes, and can be divided into different categories such as numerical, descriptive or visual. Moreover, data may be raw or analysed, experimental or observational, confidential or publicly accessible. Research data can include laboratory notebooks, field notebooks, primary research data, questionnaires, audiotapes, videotapes, models, photographs, films and test responses.
3.Reveal the data at several levels of detail, from a broad overview to the fine structure
It is generally understood that a specific characteristic (feature/column) of structured data can be broken down into one of four levels of data. The levels are:
As we move down the list, we gain more structure and, therefore, more returns from our analysis. Each level comes with its own accepted practice in measuring the center of the data. We usually think of the mean/average as being an acceptable form of center, however, this is only true for a specific type of data.
Nominal
Data
Nominal data is named data which can be separated
into discrete categories which do not overlap. A common example of
nominal data is gender; male and female. Other examples include eye
colour and hair colour. An easy way to remember this type of data
is that nominal sounds like named, nominal = named.
Ordinal
Data
Ordinal data is data which is placed into some kind of
order or scale. (Again, this is easy to remember
because ordinal sounds like order). An example of ordinal data is
rating happiness on a scale of 1-10.
In scale data there is no standardised value for the difference
from one score to the next. This can be explained in terms of
positions in a race (1st, 2nd, 3rd
etc). This is ordinal data because the runners are placed in order
of who completed the race in the fastest time to the slowest time,
but there is no standardised difference in time between the scores.
For example the difference in time between the runners in first
place and second place is by no means the same as the difference in
time between the runners in second and third place.
Interval
Data
Interval data is data which comes in the form of a numerical value
where the difference between points is standardised and meaningful.
The most common example of interval data is temperature, the
difference in temperature between 10-20 degrees is the same as the
difference in temperature between 20-30 degrees.
Ratio
Data
Ratio data is much like interval data – it must be numerical values
where the difference between points is standardised and meaningful.
However, in order for data to be considered ratio data it must have
a true zero, meaning it is not possible to have
negative values in ratio data. An example of ratio data is
measurements of height be that centimetres, metres, inches or feet.
It is not possible to have a negative height. When comparing this
to temperature it is easy to consider the difference between
interval and ratio (which may be a little confusing at first!), as
it is possible for the temperature to be -10 degrees, but nothing
can be – 10 inches tall.

CASE 20 Enron: Not Accounting for the Future* INTRODUCTION Once upon a time, there was a gleaming office tower in Houston, Texas. In front of that gleaming tower was a giant "E" slowly revolving, flashing in the hot Texas sun. But in 2001, the Enron Corporation, which once ranked among the top Fortune 500 companies, would collapse under a mountain of debt that had been concealed through a complex scheme of off-balance-sheet partnerships. Forced to declare bankruptcy, the energy firm...
