What tools do data analysts use?
A data analyst relies on various tools to collect and make sense of the data they work with. They use specialized tools to efficiently gather data from different sources such as social media, news pages, and publications, as well as tools to sort and categorize data to visualize that data for reports and presentations.
These are other important tools data analysts use on the job:
- Google Analytics (GA) helps data analysts gain an understanding of customer data, including trends, areas where customer experience can improve (eg. On landing pages or calls to action (CTAs).
- Tableau is a free software to aggregate and analyze data. Through this software, data analysts can create and share dashboards with different team members and create visualizations.
- Jupyter notebooks to make it simple for them to test code.
- AWS S3 (a cloud storage system) that they can use to store and retrieve large datasets.
- Python is able to handle text data really well. It can be assembled on any platform like an SQL server, a MongoDB database, or JSON.
- Excel is a widely used analytical tool in almost all industries. It features the advanced business analytics option, which helps in modeling capabilities like automatic relationship detection, the creation of DAX measures, and time grouping.
Data Analyst Career Paths
Data analytics is a fast-growing field, and skilled analysts are in high demand across all industries and domain types, including education, healthcare, construction, media, retail, and even real estate. The great thing about data analytics is that it relies on a broad range of skills that are often transferable.
Since their expertise is required across multiple industries, a particular data analyst professional can follow a career path that combines their analytical skills with a particular area of interest. Depending on the industry of interest, one could get job positions such as financial analyst, healthcare analyst, machine learning analyst, digital marketing analyst, among others.
Further down their career path, many data analysts tend to go on to become data analytics consultants. These analysts usually work for consulting firms, but many opt for self-employment. Finally, skilled analysts can also find roles in academic research or government advisory bodies.
These options just go on to prove that the data analytics profession leads to a more flexible career path, depending on interests, experience, and ones’ aspirations. Thus, it’s important to gain knowledge, gain hands-on experience, and hone your skills.
