9 must-have skills to become a Data Scientist in 2020

Utilizing the use of big data, as an understanding producing motor has driven the interest for data scientists at the big business level, overall industry verticals.

Regardless of whether it is to refine the procedure of product development, improve client maintenance, or mine through the data to discover new business openings—associations are progressively depending on the skill of data scientists to support, develop, and exceed their opposition.

top 9 skills needed to be a data scientist


Subsequently, as the interest for data scientists builds, the discipline presents an enticing career path for students and existing experts.

Following are the 9 must-have skills needed to be a data scientist

1. Fundamentals

To master a skill, fundamentals are of utmost importance. So, some of the basic skills needed by every data scientist are :

  • Matrices and Linear Algebra Functions
  • ETL ( Extract Transform Load )
  • Reporting VS BI (Business Intelligence) VS Analytics
  • Matrices and Linear Algebra Functions
  • Hash Functions and Binary Tree

2. Understanding of Statistics

The essential building blocks for data science are Hypothesis Testing, Probability, Descriptive and Inferential Statistics.

What is required is to have a natural comprehension of business Statistics.

Would you be able to clarify noteworthiness utilizing a p-value to a layman? Would you be able to disclose the central limit theorem to somebody new to statistics? It’s less about being an analyst. However, It’s tied in with utilizing the basics of statistics as an establishment to business analytics.

3. Statistical Techniques and Algorithms

It will be of a great advantage having exposure to algorithms like Time Series, Forecasting, Decision Tree, Logistic Regression, Clustering, Linear Regression, Random Forest, K Nearest Neighbor and their business applications.

It’s a touch of breathing space to have hands-on exposure on at least a few of the statistical techniques and a good understanding on the current happenings in the analytics business, for example, deep learning for NLP.

4. Unstructured data

It is important that a data scientist have the option to work with unstructured data.

Unstructured data is an unclear substance that doesn’t fit into database tables. Most of the people consider unstructured data as Dark analytics due to its complex nature. Working on unstructured data will be useful in untwisting insights that can be helpful in decision making.

Moreover, as a data scientist, you should be able to comprehend and control unstructured data from various platforms.

5. Programming

Data Science basically is tied in with programming. Programming Skills needed for a Data Scientist unites all the essential skills expected to change crude information into actionable insights. While there is no particular principle about the choice of programming language, Python and R are the most preferred ones.

Here is a list of programming languages and packages a data scientist can choose from:

  • Python
  • R
  • SQL
  • Java
  • Julia
  • Scala
  • MATLAB
  • TensorFlow

6. Data Visualization

The business world creates an immense amount of data frequently. The data should be interpreted in a format that can easily be comprehended. Individuals normally comprehend pictures in types of graphs and charts more than crude data.

By utilizing data visualization tools like ggplot, d3.js and Matplottlib, and Tableau a data scientist must be able to visualize data.

These tools will assist you with converting complex outcomes from your tasks to an arrangement that will be easy to understand. But the thing is, many individuals don’t comprehend serial correlation or p values.

However, you have to show them visually what those terms represent in your results. Data visualization offers organizations the chance to work with data legitimately.

They can rapidly get a handle on bits of knowledge that will assist them with acting on new business openings and remain in front of rivalry.

7. Data Ingestion

The way towards  importing , transferring , loading and processing data for later use or storage in a database is called Data Ingestion. This includes loading data from a variety of sources. Apache Flume and Apache Sqoop are some of the data ingestion tools.

8. Data Munging

Data Munging  is one of the most significant parts of the data life-cycle.

At the time of performing data analysis, you may have run over feature selection before applying an analytical model to the data.

So, in general, the activities that we do on the raw data to make it “clean” enough to input to our analytical algorithm is data munging. ‘R’ and ‘Python’ packages can be used for data mugging. 

As a Data scientist you should have a clear idea on what all features should be included and what can be removed from a dataset.  

Also, you should also be able to identify your dependent variable or label. Clearly, you need to evacuate irregularity in the dataset. 

So, all these come under Data Munging or Data Wrangling.

9. Ethical skills in Data Science

Comprehend the ramifications of your undertaking.

Firstly, Be honest to yourself.

Abstain from controlling data or utilizing a technique that will deliberately create inclination in results.

Secondly, Be moral in all stages from data collection to examination, to demonstrate building, investigation, testing and application.

Abstain from manufacturing results to delude or controlling your crowd.

Lastly, Be ethical in the manner you interpret the discoveries from your data science venture.

Conclusion

The vast majority picture data scientists as solitary mathematicians taking a shot at unpredictable and colossal data sets. However, be that as it may, this is a long way from the real world.

Moreover, aside from first rate specialized skills, data scientists ought to likewise have great communication skills to have the option to pass on and present extremely specialized data to individuals.

Also, Cooperation, business sharpness and the eagerness to grasp new advances are a portion of the key non-specialized skills that a data researcher should attempt to ace to ready to go after the worthwhile data science position openings.
