DataWrangling
Making the most of data is what data science is all about. This is when data manipulation comes in handy. Data wrangling is the process of transforming data from one form to another. This is critical since data science entails creating models, discovering new features to construct, and performing deep dives, among other things.
What can you do with Data Wrangling for Data Science?
- Reveal a deep-lying intelligence within your data by gathering data from multiple channels
- Provide a very accurate representation of actionable data in the hands of business and data analysts in a timely matter
- Reduce processing time, response time, and the time spent to collect and organize unruly data before it can be utilized
- Enable data scientists to focus more on the analysis of data, rather than the cleaning part
- Lead the data-driven decision-making process in a direction supported by accurate data
Statistics
This is one of the most required data science skill required in 2022. Data science is, without a doubt, all about getting the most of raw data. It is concerned with deriving valuable insights from unstructured data sources, to put it simply. There is no better approach to go about organising and analysing data than by using statistics. Statistics aids in the identification of correlations between data sets.
What can you do with Probability and Statistics for Data Science?
- Explore and understand more about the data
- Identify the underlying relationships or dependencies that may exist between two variables
- Predict future trend or forecast a drift based on the previous data trends
- Determine patterns or motive of the data
- Uncover anomalies in data
Especially for data-driven companies where stakeholders depend on data for decision making and design/evaluation of data models, probability and statistics are integral to Data Science.

DataVisualization
Analytical insights are a big part of data science, and hence, it is very much required as a data science skill. Meeting corporate objectives is directly proportionate to how successfully a data scientist delivers analytical insights. Do you want to know how data visualisation may benefit you? A data scientist with good visualisation skills, on the other hand, has the capacity to deliver data insights in a way that everyone can understand.
What can you do with Data Visualization for Data Science?
- Plot data for powerful insights.
- Determine relationships between unknown variables
- Visualize areas that need attention or improvement
- Identify factors that influence customer behavior
- Understand which products to place where
- Display trends from news, connections, websites, social media
- Visualize volume of information
- Client reporting, employee performance, quarter sales mapping
- Devise marketing strategy targeted to user segments
Some of the popular Data Visualization tools include: Tableau, PowerBI, QlikView, Google Analytics (For Web), MS Excel, Plotly, Fusion Charts, SAS
Building Pipelines
In data science, there will be instances where it is required to table or view a model or a data science project that does not exist. Thus, a successful data scientist is one who can write robust pipelines for your projects rather than relying on data analysts and/or data engineers. This saves time as well.

Critical Thinking
Making well-informed, appropriate decisions based on data and facts is what critical thinking is all about. This is something that any aspiring data scientist should consider. Though it may appear difficult at first, it is a data science skill that can be learned through time.
Programming
Without programming, data science is completely meaningless. A data scientist who is proficient in programming languages such as R, Python, Java, and others is more likely to succeed. This is due to the fact that the computer can only receive instructions in the form of programming. As a result, developing this data science skill is a sure bet.
In no particular order, here’s a list of programming languages and some packages for Data Science to choose from:
- Python
- R
- SQL
- Java
- Julia
- Scala
- MATLAB
- TensorFlow (great for Data Science in Python)
Solving Issues
Without a doubt, a data scientist should be capable of solving challenges. In truth, data science is linked to a slew of issues, many of which require immediate attention. It is critical to understand where to begin in order to arrive at a solution. As a result, a data scientist should be able to solve problems and translate them into long-lasting, production-ready code.

Implementation of the Model
In the discipline of data science, model deployment, or the use of a model for prediction using new data, has a lot to do with it. Such a model aids in a better knowledge of customers/target audiences, allowing the company to work toward its objectives.
Communication
Data science is concerned with converting raw data into a format that is easily understood by all parties involved in order to make better-informed judgments. This emphasises the need of having effective communication skills in place. This data science skill/ability allows you to communicate technical outcomes to non-technical team members.
Teamwork
Data scientists cannot be expected to work alone. The position of a data scientist necessitates strong collaboration with other departments like as finance, IT, and operations. This is why collaboration is so important.
