Primary Skills

The skills listed below are essential for becoming a proficient Junior Data Scientist and excelling in the role

Programming Languages

 

These are the set of instructions that Junior Data Scientists use to analyze, clean, and process data to build models for predictions and visual representations of the findings. In order to do so they are required to be aware of Python, R, or Julia.

Data Analysis and Visualization

 

It examines and organizes data to extract meaningful insights. Using this, Junior Data Scientists make informed decisions based on the analyzed data's findings and derive conclusions.

Machine Learning

 

It is a subset of artificial intelligence (AI) and computer science that focuses on leveraging data to imitate human learning processes. As a result, Junior Data Scientists must be familiar with network architecture, decision trees, and other model evaluation approaches.

Data Wrangling

 

It is the process of cleaning, transforming, and structuring raw data into a usable format. Using this, Junior Data Scientists ensure that datasets are accurate and structured for effective analysis.

Data Mining and ETL

 

It is the process of discovering hidden patterns, relationships, and insights within large datasets. These software solutions facilitate extracting data from various sources and transforming it into a suitable format.

SQL and Database Management

 

Junior Data Scientists use it to interact with relational databases. It involves creating, maintaining, and querying databases to store and retrieve structured data efficiently.

Data Storytelling

 

With the help of data storytelling, Junior Data Scientists get to translate complex data into a narrative that is easy to understand and engages the audience.

Exploratory Data Analysis (EDA)

 

It is a data analysis approach that explores data through visualizations and statistical techniques. It enables Junior Data Scientists to get a sense of data distribution, outliers, trends, and the relationship between variables.

Data Ethics and Privacy

 

It involves ethical considerations when handling and analyzing data. It is crucial for Junior Data Scientists to know about the essential aspects of protecting individuals’ rights and maintaining trust in data-driven processes.
