Data can be used for calculating, reasoning, or planning, and is often stored electronically in files or databases. But how does data is used by many companies to extract useful information to work on? That is done using a process known as Data Analysis. This is the point, a data analyst’s position becomes extremely valuable. Since businesses are still producing enormous volumes of data, there is a greater need than ever for qualified data analysts.

In this comprehensive guide, we will see the Data Analyst roles and responsibilities, the skills required to become, the tools and technologies they use, career path, and much more. You can decide if this is the perfect career decision for you by being aware of the responsibilities and needs of the role by reading this comprehensive article.

What is Data Analysis?

Data analysis comprises collecting, processing, and performing statistical analysis on large datasets to find useful information that will help the company’s growth, better decision-making, and of course, profit. In other words, It is a process of knowledge extraction from data to be used in favour of more informed decisions in business. There are normally five iterative stages involved in data analysis:

• Decide which data you wish to analyse.
• Collect the data
• Cleaning the data for analysis.
• Analyse the data
• Interpret the analysis’s findings.

Data is the new oil in the digital world we live in. It gives businesses a competitive edge, improves consumer experiences, influences product development, and powers business processes. Data analysis provides evidence of why something was done, predictive analytics allow future forecasts, and prescriptive analysis comes up with what to do. Data analytics can help those firms perform better, increase their productivity, reduce manual procedures, and implement new ideas more quickly than their rivals.

The Data Analysis Process

The volume and complexity of data that businesses have access to is only increasing, necessitating the development of an efficient and successful strategy to extract value from it. Let’s see the 5 steps data analysis process and understand it in more detail:

1. Decide which data you wish to analyse

The first step in the data analysis process is to ask yourself or the company which data they wish to analyse. Whether it is general data of the organisation, whether the organisation wants to analyse something, etc. What they need to analyse, how will you measure, and various other questions.

2. Collect the data

The next step is to gather the unprocessed or raw data sets required to assist you in addressing the specified query. Data can be gathered from secondary sources like government documents, social media, and various APIs, or internal sources like a company’s client relationship management (CRM) software.

3. Cleaning the data for analysis

To differentiate between which data is good or bad, data is cleaned to prepare it for better analysis. This often involves purging duplicate and anomalous data, reconciling inconsistencies, standardising data structure and format, and dealing with white spaces and other syntax errors.

4. Analyse the data

By employing various data analysis techniques and tools, one can curate the data to reveal trends, correlations, outliers, and variations that scream out a story. In this step, you may choose the way of data mining, where you unearth the patterns hidden within a database, or the usage of data visualisation to take information from data to an easy-to-understand form in a graphical scale, respectively.

5. Interpret the analysis’s findings

Interpret the results of your analysis to see how well the data answered your original question. What feedback can you provide to the company? What recommendations can you make based on the data? What are the limitations of your conclusions? And can make various interpretations. Share findings with stakeholders through the process of creation of reports, dashboards, and presentations.

What is a Data Analyst?
