Data science is a vast world with a great and big open source community and lots of fields inside it. And as a beginner, you're bound to make few mistakes. However, one of the most common mistakes that amateur data scientists make includes choosing a library best suited for data.
Many times rather than taking into consideration the type of data we have, constraints, and what is the aim of our project, we simply choose a library because it is the most popular one or one with a plethora of features. It is important to know that the most popular libraries are not always the ones which are best suited for our problem.
Some of the other common mistakes include-
Data Science and Machine Learning go hand in hand. While Machine Learning is the ability of a machine to find patterns from data, Data Science is the mechanism by which the machines are provided with data. The more the availability of data, the more is the complexity and difficulty in compiling new predictive models that are able to accurately and efficiently work on this data. This is where the role of Machine Learning comes in, to help Data Scientists make sense of the large amounts of data they have and to convert it into meaningful information.
As a data scientist, you have to deal with all kinds of data-numbers, text, image etc. Neuro-Linguistic Programming (NLP) helps us deal with the textual form of data and use it in our computations and algorithms. Some of the important applications of NLP are:
Below are the technical skills that you need if you want to become a data scientist.

Data science may not be as much about communication as it is about data, but however good a data scientist is, he must remember that data science is not all about crunching numbers. One of the main responsibilities of a data scientist is to communicate customer analytics as well as business insights to his customers.
Data scientists must also remember that no technology exists in a vacuum in the business environment of today. There always exists some level of integration between data, its applications as well as the people.
Thus, being able to communicate with stakeholders is a skill that every data scientist must have. Communicating with and understanding the requirements of a customer is another key priority that requires a data scientist to have good communication skills.
From its use in enabling the faster analysis of information as well as the ease it offers in recognising trends and patterns in a given set of data, data visualization is proving to be increasingly useful in the field of Data Science. No matter the size of the organization, every company with an eye towards the future is harnessing the power of data visualization.
For the same reason, every company in the world, no matter how big or small, is looking for data visualization experts who can channel this power of data visualization and use it for the faster progress of the company.
While other skills are also important in a data scientist, studies and surveys increasingly show that the ability of a data scientist to use and visualize data is a highly sought after skill in the job market these days, which is also a trend that is unlikely to stop in the foreseeable future.
The role of the data scientist is, no doubt, one of the hottest jobs in the market today and becoming a data scientist demands an ardent passion for knowledge. We have compiled a list of key points to help you decide whether data science is right for you or not.

Unstructured data refers to the undefined contents of a data set that can not be fit into structured database tables. It is basically information that is not organized in a predefined manner nor has a data model that is pre-defined. Unstructured data is generally text-heavy but may also consist of other data such as numbers, facts, figures, audio, video etc.
While unstructured data may be difficult to organize, if a company is able to tap into it in a meaningful and efficient manner, it is like digging up a bag of gold.
Unstructured data can aid companies in the formation of important business decisions if a company is able to integrate this unstructured data into their information management systems and landscapes.
Pandas and NumPy are two of the most used Python libraries for data manipulation. Most of the times they are used in a single project. Although Pandas is a library build directly off from NumPy, there are some differences between both of them.
Tabular form - CSV or SQL formats
Helps add, edit, or create columns or rows to the table.
Helps perform multiple operations on Array.
Series which is built off from ndArrays of NumPy.
ndArrays - Allow mathematical operations to be vectorized and when compared to Python lists, they are stored with much better efficiency.
Ways to access data
We can use labeled data - integers as well as numbers to label the elements of the series object.
Only integers are used for labeling the elements.
