Even the most advanced machine learning models offer little value if the results cannot be clearly translated into impactful business recommendations that leadership can rally behind. Data scientists must also coordinate with diverse contributors and functions to ensure alignment with key growth objectives. Dexterous communication and ability to simplify complex themes for non-technical audiences are paramount strengths for effective data pros.
How Can I Build Data Science Skills?
Building data science skills can be achieved through formal education, online courses, engaging in hands-on projects, and continuous self-education in areas like programming, statistical analysis, and machine learning.
For those pursuing an education in computer science, concentrating coursework on programming essentials, database architecture, statistics, modeling, and data visualization establishes a solid foundation. Gaining proficiency using leading data tools like Python, SQL, Tableau, and TensorFlow should be a priority. Many programs also incorporate projects featuring real-world datasets or case studies to provide hands-on training opportunities. Outside formal instruction, countless free online courses allow virtually anyone to start sharpening their self-education within specialized data science disciplines.
What Does a Data Scientist Do Day-to-Day?
A data scientist’s daily activities typically involve collecting and preparing data, conducting analyses, creating visualizations, interpreting the results, and communicating these findings. While specific responsibilities vary, most data scientists devote their time across phases of the data analysis lifecycle:
- Framing the Business Problem – Consult with stakeholders and data partners to identify objectives. Document priorities, success metrics, requirements, risks, and assumptions to clearly scope initiatives before analysis commences.
- Data Collection and Preparation – Identify, extract, consolidate, clean, and pre-process all relevant structured and unstructured data needed for the project from the organization’s databases and external sources if required. Resolve any quality issues or gaps.
- Initial Exploration and Visualization – Conduct preliminary analysis through descriptive statistics summaries and data visualizations to surface early patterns, trends, or anomalies that give clues on how to proceed.
- Modeling and Statistical Analysis – Select and train machine learning models, run multivariate tests, leverage predictive modeling, or apply other statistical techniques to gain robust, meaningful, and statistically significant insights from the vetted data relevant to business goals.
- Interpretation and Communication of Results – Interpret the quantitative findings, communicate key takeaways in plain language, illustrate relationships using charts/graphs, address next steps, and issue clear guidance to decision makers.
This lifecycle involves not just strong analytical chops – but also technical programming, creative problem-solving, project leadership, written reports, and public speaking to relay findings.
What Specific Tools Do Data Scientists Use?
