So you’re wondering how to become a data scientist? Ironhack has designed this guide with the intention of breaking down a data analyst’s role, the skills needed to be successful in this industry, and the concrete steps you can take as we launch into 2024. Let’s get started.
What is a Data Analyst?
Data analysts utilize a variety of statistical and analytical techniques, as well as data visualization tools, in order to identify trends, patterns, and correlations in data. This information gives companies the competitive advantage in understanding everything from consumer behavior and market trends to business performance.
The role of data analysts is only becoming more crucial today across industries as businesses become more reliant upon data to improve their decision making processes. However, pursuing a role as a data scientist comes with its own set of pros and cons:
Pro–high demand: the field of data analytics is growing rapidly, meaning that data analysts are in high demand across a variety of industries. More and more businesses are looking to data in order to make informed decisions. This means that salaries are competitive, especially for data scientists with relevant experience and expertise in specialized areas.
Pro–diverse opportunities: given that businesses across industries are looking to utilize data in order to optimize their processes and improve their decision making strategies, there are data analyst jobs in a wide range of fields. From finance to healthcare, to marketing and technology, you’ll be sure to find a data scientist job in an area that interests you.
Pro–intellectually stimulating: data analytics jobs require statistical analysis, data modeling, and other more intellectually demanding tasks. That said, data analysts can be sure that they’ll be pushed intellectually and satisfied if work that requires creative problem solving and analysis is something they're seeking.
Con–technical skill requirements: data analysts must be proficient in various tools and programming languages, which can be challenging for individuals without a technical background.
Con–long hours: big data analysis projects can be time-consuming, requiring long hours to clean, process, and analyze large datasets, especially when working on tight deadlines. Some tasks like data cleaning and preparation can become repetitive, making this work potentially monotonous for some.
Con–significant pressure: the findings of data scientists directly relate to the strategic decisions that businesses then make, that said, the pressure to deliver accurate and reliable insights is high. Faulty analyses can have significant consequences for businesses or clients, making the work of data analysts potentially high-stress.
In all, tech professionals who enjoy working with data, who face problems head on, and who are analytically inclined may find this profession highly rewarding. Of course, like all professions, the work can become stressful, but with proper stress management, data analysts can flourish.
What are the responsibilities of data analysts?
Data analysts are pivotal in helping organizations make data-driven decisions. This is done through:
Data collection: the first step for data analysis is collecting data from various sources, including databases, spreadsheets, and surveys. They ensure that the data collected is relevant to the analysis being conducted.
Data cleaning and preprocessing: the following step is cleaning data, given that raw data all too often contains errors, missing values, or inconsistencies. Analysts clean and preprocess the data, which involves handling outliers, filling in missing data, and transforming data into a suitable format for analysis.
Data analysis: data scientists use statistical methods and data analysis tools to explore and analyze data sets. They identify patterns, trends, correlations, and anomalies within the data to extract meaningful insights.
Data modeling: analysts create mathematical models and algorithms to better understand complex data relationships. They may use a variety of techniques including regression analysis, clustering, or machine learning algorithms for predictive analysis.
Data visualization: analysts present their findings through visualizations like charts, graphs, and dashboards. Visualization helps convey complex findings in a clear and understandable manner such that stakeholders with non-technical knowledge can engage data and make informed decisions.
Ethical considerations: data scientists must handle data responsibly, ensuring compliance with data protection and regulations and ethical guidelines. They must maintain data privacy and confidentiality while conducting analyses.
Through performing these responsibilities, data analysts provide immensely valuable insights to their organizations. Those insights lead to strategic and operational decisions within organizations.
