Anatomy of Data Scientist Skills Checklist

Technical Data Scientist Skills

1. AI/Machine Learning

As the data science field evolves, organizations increasingly rely on explainable machine learning algorithms. 

To stay ahead, data scientists must be well-versed in techniques such as SHAP and LIME, which allow for better communication and interpretability of models. 

Additionally, a solid understanding of fundamental algorithms like Naïve Bayes classifiers, decision trees, and random forests is essential.

2. Statistical Analysis

Statistical analysis forms the backbone of data science, enabling data scientists to apply various techniques and concepts to large datasets. 

Proficiency in probability, variance, distribution curves, and standard deviation is crucial for gathering, analyzing, and interpreting data. 

Familiarity with statistical software such as SAS is also desirable, as it enables data scientists to extract insights from data efficiently.

3. Understanding of SAS and Other Analytical Tools

Employers often require data scientists to have a strong background in Statistical Analysis Systems (SAS), a popular tool for business intelligence.

Proficiency in SAS and its integration with other tools like Excel and Outlook is highly valued. 

For example, even taking a beginner Python course can vastly improve your data processing and analysis capabilities.

4. Software Engineering

Data scientists often work on full-stack development projects, requiring proficiency in software engineering. 

Strong programming skills in languages such as Python, R, Java, JavaScript, and Scala are essential for building and delivering machine learning modules. 

Additionally, knowledge of DevOps and MLOps (Machine Learning Operations) strategies is advantageous for collaboration and managing the machine learning lifecycle.

5. Big Data

With the exponential growth of data, a solid understanding of big data concepts and tools is crucial for data scientists. 

Concepts such as volume, value, variety, velocity, and veracity (the 5 Vs of big data) should be familiar to data scientists. 

Additionally, data scientists should be well-versed in the 5 A?s of big data: agility, accuracy, adoption, automation, and accessibility. 

This knowledge enables data scientists to work effectively with large and complex datasets.

6. Writing SQL Queries & Building Data Pipelines

Data scientists often need to extract and manipulate data using SQL queries and build data pipelines for data processing and analysis. 

Proficiency in SQL is essential for querying databases and retrieving relevant data. 

Additionally, data scientists should be proficient in data wrangling techniques to transform and cleanse raw data for analysis.

 

7. Data Analysis

Data analysis is a core skill for data scientists, enabling them to extract insights from raw data. 

Proficiency in structured query language (SQL) and spreadsheet tools is crucial for processing and computing large datasets. 

Data scientists should be able to extract data from primary and secondary sources, organize it in an easy-to-read format, and present findings to stakeholders effectively.

8. Data Visualization

Data visualization is the art of presenting data in a visually appealing and informative manner. 

As a data scientist, you must be proficient in tools like Tableau and D3.js to create various types of visualizations, including scatter plots, pie charts, bubble charts, line graphs, and heat maps. 

Effective data visualization skills enable you to communicate complex insights to non-technical stakeholders.

9. Data Wrangling / Feature Engineering

Data wrangling, or feature engineering, involves transforming and cleaning raw data for analysis. 

Data scientists should be skilled in converting data from one format to another, exploring feature upgrades, and performing deep dives into data. 

Feature engineering skills enable data scientists to extract valuable features from raw data and build accurate predictive models.

10. Natural Language Processing

Natural Language Processing (NLP) is a branch of artificial intelligence that focuses on understanding and analyzing human language. 

Proficiency in NLP is valuable for data scientists, as it enables them to build chatbots, perform sentiment analysis, and extract insights from unstructured text data. 

Knowledge of NLP algorithms and techniques like text classification and named entity recognition is essential for data scientists working with textual data.

11. Deep Learning

Deep learning is a subset of machine learning that focuses on training neural networks with multiple layers to solve complex problems. 

Proficiency in deep learning algorithms like Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), and Recurrent Neural Networks (RNNs) is highly in demand. 

Deep learning skills enable data scientists to build advanced analytical models for tasks such as image classification, natural language processing, and recommendation systems.

Soft Skills Needed for Data Scientist

In addition to technical skills, data scientists must possess certain soft skills to excel in their roles, therefore having the following skills is crucial to completing your data scientist skills checklist. 

These skills enable effective communication, problem-solving, and collaboration with stakeholders. The following soft skills are highly valued in the field of data science:

1. Data Intuition

It is the ability to go beyond surface-level data analysis and draw valuable insights from complex datasets. 

It requires experience and exposure to different types of data projects. 

Developing data intuition allows data scientists to uncover hidden patterns and trends that can drive business success.

2. Great Communication

Strong written and oral communication skills are essential for data scientists. 

Effective communication enables data scientists to convey complex findings to non-technical stakeholders clearly and concisely. 

Data scientists should be able to articulate their thoughts and ideas effectively, facilitating collaboration and understanding across teams.

3. Proficient at Working with Unstructured Data

Working with unstructured data can be challenging, as it lacks a predefined structure and requires manual analysis. 

Patience, attention to detail, and the ability to extract valuable insights from unstructured data are crucial skills for data scientists.

Proficiency in techniques such as sentiment analysis and text mining can greatly enhance the analysis of unstructured data.

4. Developing Metrics

Data scientists should be proficient in developing metrics that measure the impact and effectiveness of data-driven initiatives. 

This involves creating metrics, writing code to automate their calculation, and presenting the findings to stakeholders. 

The ability to develop meaningful metrics that align with business objectives is highly valued in data science roles.
