Data Analytics – Formats  and Types 

1) Big Data

2) Structured and Unstructured Data

3) Metadata

4) Real-time data

5) Machine data

Big Data –

Big Data is a term to describe a huge volume of complex data that databases of traditional database management applications can’t use.  Big Data is characterized by the 5 V’s which are Volume, Velocity, Value, Variety, and Veracity. Volume determines the quantity of data, Velocity refers to the speed of data growth, variety describes its source and Veracity refers to the quality of data.

Structured and Unstructured Data –

Structured Data is a traditional data model of rows and columns whereas unstructured data is in the form of pictures, text, or video.

Metadata –

Metadata is another form of data that reads and provides information about other different data such as unstructured data.

Real-time Data

Data that is processed and presented at the same time is called Real-Time Data. Real-time data is very useful in stock markets to take decisions upon information received at that moment.

Machine Data –

Data generated automatically from machines such as physical devices, software, and clouds collectively called IoT’s ( Internet of Things) is called Machine data.

 Types of Data Analysis 

1. Diagnostic Analysis
2. Predictive Analysis
3. Prescriptive Analysis
4. Statistical Analysis

1. Diagnostic Analysis

Diagnostic Analysis identifies the root cause by identifying and collecting additional data and reporting to outliers about why the event occurred. For example, if a descriptive analysis tells you 5% of sales dropped, Diagnostics Analysis will tell you the root cause of the 5% drop in sales.

2. Predictive Analysis

As the name predicts, Predictive analysis is about predicting what is likely to happen in the future of a given problem. Predictive analysis is very beneficial for business planning. Predictive Analysts create a model and use the relationship between set variables to make predictions. For Example; Predictive Analysts may predict a co-relation between off-season and drop in sales. Hen based on this business may spend less on advertising campaigns and so on.

3. Prescriptive Analysis

Prescriptive Analysis looks into what happened and why it happened and what is the best course of action that can be taken to avoid the problem in the future. Google Maps serves as the best example here. It considers all the best possible routes to reach a point by all modes of transport.

4. Statistical Analysis

Statistical Analysis looks to answer the question – What Happened? This type of analysis comprises data collection, interpretation, and then a presentation on the dashboard. Statistical Analysis is further divided into Descriptive, Inferential, and Text Analysis

a) Descriptive: Here Analysts summarize numerical data by means, deviations, and percentages in the form of categorical data.

b) Inferential: This involves working with samples from given data. Analysts come to different conclusions from the set of data by choosing different samples.

 c) Text: Text Analysis is also called Data Mining and is one of the most direct methods of data analysis. Text Analysis uses databases and data mining tools to know patterns of large datasets. Data Mining or Text Analysis helps convert raw data into useful information.

So What is Data Analytics and Why It Is So Important in Business? 

Data Analytics is a process of collecting, cleansing, and visualizing data and drawing conclusions about the results they contain. The techniques used in Data Analytics enable to extraction of raw data and drawing patterns to get insights from it. The importance of Data Analytics is increasing at a rapid speed, today Data Analytics is seen as a crucial part of businesses for planning on resources, making financial decisions, and meeting customers’ expectations.

Data Analytics Helps In:

• Targeting Customers
• Reduced Operational Costs
• Problem-Solving
• Effective Marketing
• Customer Service
• Smooth Operations

For businesses to understand and interpret solutions in a meaningful way, data analysis is crucial. In simple terms, data is the organization, interpretation, structuring, and presentation of information. As organizations become more technologically savvy, they are also becoming more research-driven.

Today, any business that wants to make scientific decisions needs to analyze data. The process is streamlined, money is saved, and customers are offered what they want. Businesses do not want to invest in advertising campaigns and target demographics that have some interest in their products and services.

Data analysis helps businesses to track their product’s performance on targeted demographics. Through data, analyzed businesses get a clear picture of targeted audiences’ spending habits and their interests.  The data also helps them in setting prices and determining the average length of advertising campaigns and some cases even calling off the product.

As a result of data analysis, Coca Cola beverage giant created a hashtag #Shareacoke to increase customer retention and acquisition, Netflix uses data analysis to target its advertisement campaigns to reach success. Amazon uses innovation to make products.

Data Analysis Testing Methods

Quantitative Data Analysis is done by working with numerical variables like statistics, percentages, and measurements. It involves using algorithms and mathematical analytical tools to get insights for any value.

Techniques of Quantitative Data Analysis 

Regression Analysis is a statistical method to predict an outcome of historical data, it helps in understanding and building a model to predict the outcome based on the model.  Regression analysis is used to predict behaviors of both dependent and variable factors.

For example, if you want to know what type of Vine people buy, then you would find data on people, their age, financial status, etc who buy vine. Regression Analysis has two primary types:  Simple Linear and Multiple Linear

Simple linear regression analysis is a mathematical representation of a single independent and normally dependent variable. Whereas, In Multiple linear aggression, there are multiple variables with the normal dependent variables. Multiple linear regression models can help in complex relationships of different features and can help to map relationships between multiple variables.

On the other hand, Qualitative Data Analysis is mostly used by businesses. This approach is non-numerical and works with certain identifiers say labels, and statistical percentages. Quantitative Data Analysts may use interviews, observation, and review documents to get a result.

This type of method is also called the Bottom-up approach as it involves building a set of ideas from a specific view.

In the deductive approach, a researcher is drawn to achieve an accurate answer given that the results are established.  There is no possibility of any invalid conclusion if no mistakes were made.

Excel, SQL, Tableau, or Python – Which Technology Do I Learn First?

Many learners have this question in mind when they hear of tech knowledge required for any particular course they want to start with. Learning Excel is one of the best ways to get started in the field of Data Analytics and excel is such a software that many are intermediate level. Many employers still run their entire data analytics through excel. So, job opportunities for skilled excel data analysts are also there.

If you know excel then learning SQL is a good decision. SQL is a query language for databases like  MySQL, and PostgreSQL, online data analysis courses are more focused on syntax and data modeling. Many businesses store their company data in SQL databases and appoint an analyst to extract, summarize and create a report.

After you have learned about SQL and got some spreadsheet experience, you can move on to learn R. R – Ruby language program is used for statistical computing, scientific research, Data Analytics, visualization, and presentation of data. It is more object-oriented. It emphasizes quality reporting for visualizations and creating interactive web applications.

The R language is designed for Data Analysis and is important to have good knowledge if you want to have a career in data science. However, there are certain drawbacks in R such as slow performance and lack of testing features are some of the reasons that most data scientists and analysts prefer to look for other languages such as Python.

Python is a powerful and versatile language used for various computer tasks like building websites, automating tasks, and doing data analysis. Its flexibility for beginners has made it one of the most used planning languages today. Python is used in the fields of Artificial intelligence, Web development, Mobile application, and Game development.

It highly depends on your goals to learn there are several factors to consider before your start. SQL is interesting to learn because its paradigm is different. SQL robustly handles data. For Example, SQL can handle huge data and can at the same time handle crashes and keep the database system still in a consistent state.

For Data Analysis you follow a process where you need to gather raw data, and clean and build algorithms. You will then visualize and create a report. To manage data, as a first tool you’d require SQL or NoSQL databases. NoSQL has gained popularity with big data like the data managed by Google, and Facebook.

Given the current situation of the world, businesses are becoming more data-oriented, hence getting to know SQL is very useful. On the other hand, for job prospects, the best would be Python then SQL, and then R.
