It’s a career that requires both soft and technical skills in order to fully maintain the confidentiality, integrity, and availability of an organization’s digital assets.
What is Data Analytics?
Data analytics is the process of breaking down, cleaning, processing, and transforming raw data with the intention of securing insights that help companies make stronger data-driven decisions. Data analytics is a huge field that uses a wide range of techniques and methodologies in order to uncover patterns, trends, relationships, and other valuable information from large datasets.
Today, data analytics is utilized across industries to support organizations in making data informed decisions, solving complex problems, and optimizing their operations. The verstitle ways in which data analytics can aid companies is what makes it one of the fastest growing fields in the United States. The U.S. Bureau of Labor Statistics (BLS) estimates a 22% growth in the industry through 2030, meaning that more than 3,000 new job positions in data science will need to be filled each year. Knowing that, what exactly does it entail to be a data analyst?
What Responsibilities Do Data Analysts Have?
Data analysts must collect, process, examine, and pull meaningful insights from raw datasets. The conclusions drawn from the trends, correlations, and relationships in data sets are then utilized to make informed recommendations to organizations on how to best optimize everything from production processes to marketing campaigns. The work varies depending on the organization, but key responsibilities include:
Data collection: it’s upon data analysts to collect relevant data from numerous sources. These include databases, spreadsheets, websites, and social media platforms, among others.
Data preparation: ensuring data quality and accuracy is part of the data preparation process. Raw data is often overwhelmed with inconsistencies, missing values, and other anomalies. Data cleaning is crucial in identifying and resolving issues pertaining to data accuracy and reliability.
Data filtering: generally data must be transformed and organized such that it’s suitable for analysis. This involves updating, filtering, and normalizing data to make the analysis manageable and valuable.
Exploratory Data Analysis (EDA): EDA is the process of visualizing and summarizing data sets in order to identify trends, patterns, and other correlations within the data set.
Machine learning: this data analysis technique utilizes algorithms in order to build predictive models that give organizations insights into future outcomes based on historical data. Machine learning and predictive analysis are often used in fraud detection and customer behavior prediction.
Visualization and reporting: this is a huge piece of data analysis. The insights uncovered are only as relevant as the analyst’s ability to communicate them to stakeholders. Data analysts use charts, graphs, and other images to communicate findings to non-technical stakeholders.
These are just a few of the many responsibilities of a data analyst. It’s important to note that the work straddles technical analysis work and tactical communication skills in order to present findings. The field is constantly evolving with the introduction of artificial intelligence and other techniques that aid analysts in extracting insights from data sets.
Cybersecurity vs. Data Analytics
Data analysis and cybersecurity are two distinct areas of work, however, they overlap and can complement each other. As we know, data analysts focus on the collection and exploration of data, while cybersecurity professionals look to protect and make more resilient computer networks.
