Quotes gradually emerge as the things are on rise. Same is with the Big Data. Here are few original Data Quotes by me.
1.) A Dashboard is worth a thousand tables filled with raw data.
2.) Data sets on a graphical tree is just like apples on a tree more like a picture, transparent and easy to sum up.
3.) Not Always Relevant Information needs to be dug up from Bulk and Complex Data. Sometimes it is apparent.
Hello All,
Wait! Is Bulk and Complex Data killing your time and efforts. Go through the following article to reduce your efforts to a minimum level.
The word torture in the picture above means processing the data using some algorithms and tools. There are two ways of analyzing the data or doing research work over data. One is Qualitative Approach while other is Quantitative.
Differentiating them below –
| Qualitative | Quantitative | |
|---|---|---|
| SUPPOSITION(theory) | Large | Small |
| DETAILS | Complete picture | Steady/Focused |
| Type of Analysis | Exploratory | Conclusive |
Qualitative analysis goes in phase 1 when data is gathered and maintained in the form of a dashboard or graphical manner. Quantitative analysis comes in phase 2 when data is bulk and complex, maintained in separate entities. Entity here is one data table full of records.
Qualitative analysis is exploratory and/or investigative. Findings are not conclusive and cannot be used to make generalizations over present data. It only helps in deducing the facts in initial phase, helps in further proceedings.
On the other hand Quantitative analysis is used to recommend a final course of action. Conclusive in nature.
For Example – “”A lawyer “X” who is say a criminal defense lawyer. X discusses the case with his client, cross examines the witnesses, tries to negotiate a deal between the client and the prosecutor so as to solve some amount of case outside the court. All this happens in the initial phase.
X has the data fed to him by his client and several other witnesses. X also has his own legal data, rules, procedures. X follows Qualitative approach in the initial phase so as to reach to some decisive understanding.
This approach helps X in trying negotiations. If prosecutor is unwilling to negotiate then X manipulates the data sets again just to figure out some way of getting the sentence of his client reduced.
After the initial phase X gets time from the court to prove his client’s innocence to some amount. He then follows a Quantitative approach in which he goes through the situation and details in a focused manner and prepares some expert witnesses to make his case strong and may also hire some investigators to bring more evidence again ‘data’ and thus the prosecutors case may seem less credible and results might go in favor of X’s client””
“So we saw X gets Input which is Raw Data from his client, witnesses, observations, legal artifacts and after analyzing it thoroughly he concludes the case from his side.”
Qualitative analysis is Non Statistical while Quantitative analysis is Statistical.

This blog will differentiate Data Analysis and Data Interpretation.
Data analysis is making a summary of gathered data. This is what a Data Scientist does.
Data Interpretation is extracting the meaningful information out of the summarized Data. After research Data Scientist does this too.
Data analysis starts just after collecting the data. The data is divided into analytical units, modules based on patterns. For Example “A class teacher maintains a register of attendance for two classes. At the end of the month she finds out the worst offenders. She divides the data into two sets first. Class A and Class B. The two sets become two separate analytical units which are then analyzed separately. Further she divides each set into different modules based on patterns such as a student remains absent every Tuesday. She then calls student’s parents to ask for his/her absence on a particular day every week.”
So this is the traditional way of managing and making summary of the data. So In the above example, Teacher collects data of two classes for the whole month then she analyzes it before interpreting it to the offender’s parents.
This way of managing the data is manual which can be automated as per the requirements using several coding techniques like VBA, VB.NET, Java etc.
So the 4 basic steps of processing Data are concluded as follows : –
1.) Collecting Data (Surveys, Reports, Gather etc etc)
2.) Analyzing Data (Analyzing Causes. effects and Consequences)
3.) Summarizing Data (Bringing Data into Readable Format)
4.) Interpreting Data (Displaying Findings & Stating what’s missing)
My Next Blog will focus on Qualitative vs Quantitative Research.
The scope of data analysis has increased by leaps and bounds. Data analysis is becoming important across all industries and if used wisely, it will prove beneficial.
Data analytics is widely used by many business organizations to better understand their customers. Traditional methods such as reports and dashboards are running obsolete. Businesses are not only looking at data analysts to only understand and interpret data, but also to work with the organization’s leadership teams to facilitate strategic decisions. 35% of data analysts work with the management, 33% with the IT Admin, and 36% as programmers while 23% as graphic designer.
Once there was a boom in IT and telecom domain, the time again has come for boom in analytics domain. Demand for Data analysts will be there in each and every small or big company.
My Earlier Blog was focused on Data Analysis which is the main subject of Analyst’s Digest.
This blog explains the meaning of data. People must have learned the basic definition that Data is a collection of records. My question is what are these records, what constitutes a record?
Record is nothing but certain pieces of things set in writing or typed or stored in some kind of storage devices for later references. These records when pile up forms data. “BIG DATA”. Lets get into Data then.
Data is a collection of Facts be they assumed or known & Statistics such as values or measurements. More precisely Data consists of texts, numbers, descriptive or non descriptive records, boolean values that are true or false, comments, status, etc.
Moreover Data can be qualitative (that is descriptive, argumentative) or quantitative (Statistical, Numeric). Data takes various forms when we look into its most basic format which is raw. Data in quantitative form may be discrete or continuous. The Continuous data is easy to simplify into meaningful form.
Till Now we have talked about various forms of data. But readers might be wondering that where does this data come from? What leads to such big and cluttered data?
Data gets collected by several means or say procedures.
1.) Observation or Survey. For example – Scientific Experiments, Survey of population etc.
2.) Collecting Information. For Example – Attendance in a school, Work Status in a corporate.
3.) Providing Solutions and Services – For Example – Keeping Various trackers in a corporate company for the work delivered to a customer.
4.) Emailing – Gmail , Yahoo etc. Mails = Data.
So Data can be biological, environmental, Scientific, agricultural, academic etc.
My next blog will highlight some broader aspects of data analysis. Till then keep on playing with data and try to come up with new and unknown algorithms, models to filter meaningful information.
The Prime task is to understand what is a data analyst and what he/she does?
Lets ponder over verb first.
Data Analysis means analyzing or inspecting the data, be it in bulk or in insignificant amount. The Data analyst after proper analyzing the data deduces the conclusion and develops or brings the end result in a format which is immensely meaningful and readable.
While the Data Analyst is a medium, the Data Analysis is a process that follows several steps to convert Data into a meaningful information.
I would not hesitate in calling Data Analyst a Tool who runs several algorithms and applies Data Analysis Models & performs various mathematical calculations to extract and classify information from unstructured data.
