New York City, New York Feb 15, 2021 (Issuewire.com) - With the rise in technology and awareness, most organisations have realised the value of data-driven organisational strategy, which has made them search for talented individuals who can provide them with an insight into a continuous stream of accumulated data. Findings reveal that about 70% of the US executives would prefer candidates for jobs with good data skills by 2021. Moreover, for data analysts, the demand is likely to grow as we are a physical world continuously moving towards digitisation to make systems smarter, quicker, automatic, precise, and time-saving rapidly.
If you have just begun his/her research and are mapping out how to transition your career into data analytics, you are not alone. Reviewing job posts regarding data-driven positions can be one of the starting points. However, various analyst roles are incredibly nuanced, making it tough to understand which skills are best to invest in.
Here Are Five Crucial Skills That Every Data Analyst Should Instill:
1) SQL Or Structured Query Language
SQL is a domain-specific language required for programming and designed for efficiently managing data/info held in RDBMS or relational database management system or for stream processing in RDBMS or relational data stream management system. Used explicitly for handling structured data or incorporating relations among variables and entities, SQL is possibly one of the crucial skills a data analyst should know. This language is frequently considered a graduated form of Excel as it can handle massive datasets that MS Excel simply cannot. Important SQL clauses such as SQL SELECT Statement, SQL ORDER BY, SQL LIMIT, SQL Logical Operators, SQL BETWEEN, SQL Data Types, SQL CASE Clause, and SQL WHERE data analysts can use the clause with Comparison Operators to avail prudent answers via database.
SQL is required by the leading organisation for reasons like managing and storing data, relating multiple databases, or changing or building databases altogether. Month on month, various job postings regarding the search for SQL skills are posted online, where the median salary for those with advanced SQL knowledge is set over $75000. You can go through SQL Tutorials available online to brush your skills on SQL.
2) Microsoft Excel
When it is about MS Excel, the spreadsheet is the first thing, which is likely to strike anyone's mind. The tool is a lot more than just a spreadsheet. Though programming languages such as Python or R are best suited to manage huge data sets, Excel methods in an advanced form such as Macros and VBA lookups are widely used for smaller lifts for quicker analysis. If you are one of those working in a lean organisation or a startup, the first version of the database might be in Excel form. Over decades, the tool has stayed a mainstay for organisations across numerous industries, so learning this is important. Fortunately, there exist plenty of free resources online to assist you in getting started. Also, structured data analytics classes are available online for those who want a deep understanding of MS Excel.
3) Critical Thinking
To use data to answer particular queries, you require finding out what you should ask first, which in most cases can be tricky. To become a pro in data analysis, you need to think like an analyst. The role of an analyst is to scrutinise, uncover and lastly synthesise unclear connections. While such abilities are generally innate to a particular extent, you can try several tips to facilitate your critical thinking potential. For instance, continuously asking ground-level questions regarding issues at hand can assist you to remain grounded when you are out searching for solutions, rather than just getting carried away with a read explanation that is more complicated than usual. Moreover, it is essential to think by yourself rather than simply sticking with what already exists.
4) R or Python-Statistical Programming
What Excel can perform, Python or R can perform in a better way at least 10 times faster. Similar to SQL, Python and R can manage what MS Excel cannot. They are powerful programming languages about statistics, which can be used to carry out advanced analysis and even predictive analytics on a bigger data set. To become a data analyst in the real sense, ensure to go ahead of SQL and master well at least one language.
Both Python and R are free and open sources, and employers, in most cases, do not care which one of the programs you are choosing to complete their work as long as their work is accurately done.
5) Data Visualization
Having the potential to share a compelling story through data is necessary to get your point to stand out in bold and keep your target audience engaged. In case your findings cannot be quickly and easily spotted, you may have a tough time getting through your work and others. For this purpose, the art of data visualisation can either have a make effect or a braking effect when it is about the impact of your data/info. Most analysts take eye-catchy and high-quality graphs and charts to show findings in a precise and clear manner.
