What does a Data Analyst do?

A Data Analyst analyses the company's raw data and develops methods to make it easier for other people to comprehend, see trends, or predict future events. Data Analysts assist organisations in converting unwieldy quantities of data into something useful.
 

Data Analyst job responsibilities include: 

  • Creating an information architecture for a data set and ensuring that it is readily accessible and understandable to all users 
  • Make recommendations on how the organisation may best utilise the data they currently have to their advantage or make suggestions about what new data should be collected 
  • Examining how companies in comparable sectors utilise their data analysis tools 
  • Combining previously unrelated sets of data so that they may be more easily studied 
Data Analysts frequently employ statistical methods on the data they have acquired. This is due to the fact that raw numbers must be transformed into information that can be easily understood by decision-makers. An analyst must have a thorough grasp of algorithms, statistics, and mathematics to do this kind of work well. Because much of the job includes collecting, processing, and analysing huge quantities of data using computer software. 

This position demands strong analytical abilities. Professionals in this field should have a thorough knowledge of statistical analysis software tools such as SQL, R, or Python programming languages. They must also be able to write reports effectively and communicate well in written format. Businesses require individuals to discover new applications for their data or develop innovative solutions that haven't been considered before, having the ability to think outside the box is also essential. 

What technology does a Data Analyst use?

A Data Analyst will need tools that allow them to gather, store, and access data quickly and efficiently. The following are some of the most popular technologies in this sector: 

  • Microsoft suite 
  • SAS 
  • R programming language 
  • SQL databases 
  • Google Analytics 
  • Excel spreadsheets 

Text mining applications, such as Apache OpenNLP or IBM Alchemy Language, are frequently used by Data Analysts to automate the conversion of unstructured text into structured information. 

As the world becomes increasingly automated, Data Analysts must be well-versed in all things technological. They must also be able to make judgments about which software would be appropriate for a specific purpose. 

They may also leverage machine learning algorithms and tools to find trends in a data set that would go unnoticed by humans.
