Whether you’ve just graduated from school or are looking to switch careers, the first step is often assessing what transferable skills you have and building the new skills you’ll need in this new role. Take a look at some job listings for roles you’d like to apply for, and focus your learning on the specific programming languages or visualization tools listed as requirements. We’ve curated a collection of resources to help you decide whether becoming a data analyst is right for you—including figuring out what skills you’ll need to learn and courses you can take to pursue this career.
Handling Missing Data
- Healthcare organizations use data analytics to develop personalized treatment plans based on individual patient characteristics.
- Data analytics is all about using data to gain insights and make better, more informed decisions.
- Typically, data analytics professionals make higher-than-average salaries and are in high demand within the labor market.
- By collecting data from sensors across the city, traffic lights can adjust in real time to help improve the flow of vehicles and make cities more efficient and cleaner.
- Most business questions are focused on the things that are not happening, so any unnecessary gaps in the data may lead to wasted work, as the wrong follow-up questions get asked.
- At its core, data analysis is about identifying and predicting trends and figuring out patterns, correlations, and relationships in the available data, and finding solutions to complex problems.
As you can see from these two case studies alone, data analytics can be extremely powerful. This kind of personalized service has a major impact on the user experience; according to Netflix, over 75% of viewer activity is based on personalized recommendations. Data analysts are typically expected to be proficient in software like Excel and, in some cases, querying and programming languages like SQL, R, SAS, and Python.
- Data analysts typically work with existing data to solve defined business problems.
- This creates hybrid systems that balance immediate response with in-depth analysis.
- These systems analyze vast datasets to detect relationships, anomalies, and recurring structures without explicit programming for each scenario.
- In marketing, for example, cluster analysis may be used to identify distinct target groups within a larger customer base.
- Data analysis is the practice of working with data to glean useful information, which can then be used to make informed decisions.
- Manufacturers use data analytics to improve production efficiency, predict maintenance needs, and enhance supply chain management.
- Because of the extra complexity involved, these two types of analytics are normally performed by data scientists not data analysts.

Tutorial 1: An Introduction to Data Analytics
This combination allows businesses and organizations to deeply analyze complex data sets and derive valuable insights from them. According to Gartner research, effective data analysis practices accelerate business decision-making processes by 23% and increase operational efficiency by 17%. Predictive and prescriptive analytics often employ more complex statistical analysis and even sophisticated machine learning algorithms. Because of the extra complexity involved, these two types of analytics are normally performed by data scientists not data analysts.
Compare this to vendor-specific certifications, which equip you to work with just one platform (such as Microsoft or AWS). Choose Oracle Analytics and you’ll get a single, integrated platform that combines Oracle Analytics and Oracle Autonomous Database. It’s a simple, repeatable solution with the best elements of analytics and powerful autonomous data services.
Step 1: Data collection
If you’re still in school, ask your university’s career services office about any internship opportunities. With an internship, you can start gaining real-world experience for your resume and apply what you’re learning on the job. After gaining some experience working with data and presenting your findings, it’s time to polish your resume and begin applying for entry-level data analyst jobs. Your skills, portfolio, and enthusiasm for a role can often matter more than if you check every bullet item in the qualifications list. It used to be that most entry-level data analyst positions required a bachelor’s degree.
It uses historical data and machine learning to forecast what’s likely to happen, so you’re not just reacting to changes, but actually preparing for them. Data analytics identifies Software development bottlenecks and inefficiencies within business processes.
