In this rapidly expanding digital world, new technologies and associated roles are appearing at a rate that education system is not able to revamp its syllabus parallelly. One such technology is Data Science and the associated role is Data Analyst.
Most of the computer-related graduation courses are currently not offering Data Analytics as a major subject. As a result, most of the Data Analysts have learned the skills themselves. It indicates that you can also become a Data Analyst with no prior experience.
Fasten the seatbelts, let us board the flight that will cover everything related to the data analytics, and it will help you in becoming a good Data Analyst with no prior experience by the end of this journey.
Data analytics is actually the art of analyzing a huge amount of data collected from any particular organization or group of organizations with an intention of pulling out conclusions that will enhance the productivity of the organization and will also enhance their decision making ability on quantitative as well as the qualitative basis.
Do not confuse data analytics and data analysis, both terms hold the same meaning and are often used interchangeably.
Nowadays almost every organization which deal with any sort of data have a huge amount of data that keeps increasing with the time, data analysis can be performed over these data to get useful insights from the pool of data. For carrying out this analysis work a highly skilled person is needed and this highly skilled person is known as the Data Analyst. They are also known as Data Scientist.
What is the actual work of Data Analyst?
Data Analyst uses a proper combination of mathematics, programming tools, software, and statistical methods to draw out insights from the bulky data sets provided to them. Insights provided by the Data Analyst helps companies to re-define their products and services according to their average customer needs. Not only in product enhancement but also their insights act as an aid to marketing strategy, as well as to effective production process.
Are you looking for the set of basic skills that are needed to become a good Data Analyst?
A good Data Analyst should have the following skills:
1. Mathematics: If you are someone who does not like Mathematics and calculations then you should drop the idea of becoming a good Data Analyst. You should know about an amazing relation between mathematics and data analysis before you drop the idea of becoming a good Data Analyst: The mathematics which you studied in your school and college days were usually not related to real-life problems and situations, there are great chances that you will start loving mathematics when you start dealing with the real situations.
The degree of mathematics you need to know to become a good Data Analyst has always been a confusing and highly debatable topic. One group of people thinks that a huge amount of mathematical skills are required and another group of people says that since most of the calculations have to be done by software then there is no use of much mathematical skills to become a good Data Analyst. It actually depends on many factors. There is no straightforward answer to this. it highly depends on how an organization is defining Data Analyst. Some organizations give a title of “Data Analyst” but make you work as a “Data Engineer”, whose actual work is much inclined towards software engineering which doesn’t require many mathematical skills. Not only this, some companies hire different sets of people one who is good at Maths and calculations and others who are good at coding and finally combine them in a team for better results. On the other hand, few organizations hire someone who possesses both the skills. These were the real source of confusion. We do not want to get into this debate. Let the data guide you, DataScienceWeekly has published a list of average mathematical skills you should be possessing in order to become a good Data Analyst:
2. Programming: To become a good Data Analyst, you need to be an expert in at least one of the programming language. Though, it will be always a plus point if you are good in multiple programming languages that are commonly used in data analysis such as R, Python, C++, Java, MATLAB, PHP, etc. The capability to program helps Data Analyst in a number of ways. If there is some work that they need to perform for many times(very common case in the field of data analysis) on a daily basis, they can automate such works using scripts which will decrease the time consumption and hence will increase efficiency as well as the productivity. They can also write scripts that can transform data from one format to another which is another common task in data analysis.
3. Machine Learning: Machine learning is technology based on artificial intelligence (AI) that provides systems the intelligence to automatically learn and improve with time and experience. They are not explicitly programmed. Machine learning provides a kind of algorithm that allows software applications to become more accurate in foretelling results. Almost every small and big companies know that big data can take their company to another level, but sooner they have started realizing that big data analysis along with Machine learning is even more powerful. With an exceptional computational ability, machine learning is being effectively used in the field of data analysis. Machine learning can be used to make decisions and predictions based on data, and that is why it is very useful in data analysis..
Machine learning along with data analysis is actually helping companies in examining a large amount of data that are already very complex, to unveil cryptic patterns, expose market trends, and to get an understanding of customer taste regarding their product. When the process is automated and it is happening on a speed that manual human-based analysis can’t even think of competing, the result is extraordinary and positively surprising as well.
Let us go through a real-life scenario to understand the real application of machine learning in data analysis. E-commerce: In e-commerce, machine learning along with data analysis collect and analyze data in a dynamic environment and use the result to change the shopping environment in real time based on the behavior of the visitor on the website. It actually discovers similarities and differences in customer behavior on the website. The final result can be very interesting like visitors originating from a particular geographic location usually purchase a certain category of products, and use a particular payment method. In such cases, customers can be presented with similar products recommendations with some discount coupons depending on the company policies.
4. Statistics: If you are good at programming, mathematical, and software skills, but at the same time you do not have proper knowledge of statistics then you are lacking one of the unavoidable skill set that is required to become a Data Analyst.
If you are not good at statistics then you can give a kind of results to the stakeholders using which they may have to face a huge loss and related consequences. All good Data Analyst has a different set of skills and they work with different technologies, but one skill that keeps them under one roof is a deep understanding of statistics. So start learning statistics if you really want to work in the field of data analysis as a Data Analyst.
5. Microsoft Excel: Before performing any sort of data analysis organizing data in a systematic way and performing calculations are two of the main tasks of Data Analysts, which indicates that you should be very good at using Excel. Excel itself is very powerful, all you need is to learn how to use Excel efficiently. You will get many online guides for using Excel to its full potential.
6. Good Communication skills: Being a Data Analyst you will have to communicate with stakeholders, decision-makers, fellow Data Analysts and software engineers for collecting and sharing information and results inside the channel as well as outside the channel. Sometimes you will have to do one on one with the end clients to understand their actual requirement and also a great communication skill is needed when there is a change in plan. A good communication skill is required in all the above scenarios. Because if you are not able to communicate well, you will not be able to understand their requirement and unfortunately you won’t be able to give them the required results. All your efforts will be wasted if you are not able to present your point correctly to them. So, you need to start working on your communication skill if you are not very good at it.
Try learning new tools once you are content with ones you are already using. Not every tool work for every problem, different tools can be good for solving different types of problems.
