Data Analyst Skills and Qualities That Will Turn You into A Professional

Most businesses now understand the advantages of a data-driven business strategy and decision-making. Thus, these businesses know the importance of hiring skilled data analysts to do designated tasks which will help them offer insight into the ongoing stream of information being gathered.

Data analysts must apply a wide range of talents, from in-depth analysis to data visualisation and storytelling. You could be writing a SQL query to study a data set one moment. Then you could be explaining to a board of directors how the company needs to change in light of your findings.

What Does a Data Analyst Do?

A data analyst is a person who uses technical knowledge to analyse data and offer insights. A data analyst analyses data to discover important customer insights and useful applications for the data. They also share this information with the company’s management and other stakeholders.

Data analyst job roles also include data collection from primary and secondary sources. Performing statistical analysis of the data and database implementation and maintenance are part. Also trend identification, analysis, and interpretation.

Data Analyst Skills and Characteristics That Will Make You Professional:

Data Cleaning

A data analyst’s role includes retrieving data from one or more sources and then processing it to remove irrelevant data. This preparation is done on this for a better category and numerical analysis. Resolving missing and inconsistent data is another aspect of data cleansing.

For instance, when you get data from reviews, most of the time, the reviews include unnecessary and irrelevant comments. Removing them before conducting data analysis enables you to make decisions using the highest-quality information.

Statistics Knowledge

Statistics and probability are crucial data analyst abilities. Understanding statistics also help you confirm the validity of your analysis. It also helps prevent frequent logical fallacies and mistakes. Depending on the data you’re dealing with, a different level of statistical knowledge may be required.

R or Python Programming

R and Python are utilised to conduct sophisticated analyses on large datasets. They are also used for predictive analytics. They both adhere to industry standards. At least one of these languages must be mastered by you.

Employers don’t care which programming language their employees use as long as their analyses are accurate. This is because both R and Python are open-source and free. However, some analysts prefer R over Python for exploring data sets and performing ad-hoc analysis. This is because it was created specifically for analytics.

Data Analysis and Exploration

Data analysis, in its most basic form, entails taking a business requirement and evaluating pertinent data. This will help create a response to that question. Data analysis is also the methodical application of statistical approaches to analyse data.

Exploration is a different type of data analysis. Finding fascinating patterns of data that have the potential to benefit a business is called data exploration.

Critical Thinking

Data analysis is more than just looking at it; you must also understand it and take into account its implications beyond the scope of the numbers.

Critical thinking enables you to evaluate information, identify trends, and derive useful knowledge and concepts. You need to work harder and make a commitment to thinking as opposed to just processing.

The most challenging aspect of using data to get answers is frequently identifying the right questions to ask in the first place. You must think analytically if you want to be successful as an analyst. A data analyst’s job is to find and combine correlations that aren’t always obvious.


In the end, you must be able to explain your findings to others. No matter how intelligent and skilled a data analyst you are, if you can’t communicate the patterns you find to people who don’t understand technical terms, you’ve failed.

Being a successful data analyst requires being “bilingual.” You should be able to discuss highly technical topics with your trained colleagues. Then present concise, high-level explanations in a way that aids decision-makers.

Create Data Visualisation and Presentation

Data visualisations help to clarify trends and patterns in the data. Because most people understand charts and graphs more quickly than they do spreadsheets. This is because humans are visual beings.

Data analysts must explain their conclusions clearly by using high-quality charts and graphs. One option is to utilise a complex dashboard with interactive data elements. Also, straightforward chart and table with date filters.

Presentation abilities and data visualisation go hand in hand. But it’s okay if presenting doesn’t always come easy to you! Even seasoned presenters occasionally experience performance anxiety. Start by practicing, then practice some more until you find your rhythm, just as with anything else.

Machine Learning Skills

A grasp of machine learning has been regarded as a crucial element of an analyst’s toolset. This is because AI and predictive analytics are two of the hottest subjects in the field of data science. In the job market, having a basic understanding of related tools and concepts could give you an edge over competitors.

Attention to Detail

Data analysis requires a keen eye for detail. You should be able to locate and recognise the tiniest hints of a larger message that is concealed in plain sight in a massive data collection.

Building systems for effectively acquiring and sorting data can also benefit from having a strong eye for detail. A single coding mistake might jeopardise your entire operation. As a result, whenever handling data, you should always be on the lookout for any minor errors that could turn into more serious issues.

Research Skills

You might believe that data analysts have immediate access to all the knowledge they require to carry out their duties. Contrary to popular belief, data analysts still need to research to get all the information they want and to maximise the use of the data at their disposal.

To properly contextualise your discoveries when making visualisations or interpreting raw data, you must feel at ease conducting more research. Additionally, after you give it to your audience, it should be clear to them.

SQL and Excel

The most crucial competency for data analysts to possess is probably the ability to use SQL or Structured Query Language. It is the de facto industry standard database language. It is sometimes referred to as an advanced Excel counterpart. This is because it can work with much larger datasets than Excel can.

Almost all businesses require SQL experts to manage and store data and connect various databases. For example, the ones Amazon uses to suggest products you might like) or create entirely new database structures. Advanced Excel techniques VBA lookups and Macros are utilised for queries and quicker analytics.


As technology progresses, data analysis is becoming more and more prevalent. As more businesses, enterprises, and organisations switch to automated solutions, the need for data analysts will increase. Data collecting should not be the extent of your responsibilities as a data analyst.

If you also possess the aforementioned abilities, you can have a successful career in data analytics. You will become the ideal candidate for a data analyst position by developing these skills. This will raise your likelihood of landing a job.
