Hello everyone, I hope you are doing well. Welcome back to our channel. Today, I am going to discuss the importance of learning data analytics.
Data analytics is a field that involves analyzing and interpreting large sets of data to uncover patterns, trends, and insights. It plays a crucial role in various industries, including finance, marketing, healthcare, and more.
To become a data analyst, there are three important tools that you must learn. The first tool is a programming language, such as Python. Python is widely used in data analytics due to its versatility and extensive libraries, such as pandas for data manipulation and data visualization tools like Tableau or Power BI.
The second tool is SQL (Structured Query Language). SQL is essential for working with databases and extracting data using queries. Familiarity with SQL can be a valuable plus in your data analyst career.
The third tool is Excel. Excel is a powerful tool for data analysis, especially for smaller datasets. It offers various functions and features that can help you manipulate and analyze data.
In a data analyst interview, you may be asked various questions related to data analytics. Some common topics include supervised and unsupervised learning, missing data, and statistical concepts. It is important to have a good understanding of these topics to succeed in your interview.
Let’s take an example of an Excel question. Suppose you have a dataset with columns for city, device, and sales. You want to find the total sales for a specific category, such as laptops. In Excel, you can use the SUMIF function to achieve this.
Another important aspect of data analytics is performing year-on-year calculations. You can use SQL window functions, such as LAG, to calculate the year-on-year change in sales for each company.
Lastly, if you are interested in pursuing a career in data analytics, you may wonder about the average salary in India. According to our research, the average data analyst salary in India ranges from 3.5 to 10 lakh per year.
In conclusion, learning data analytics is crucial for anyone aspiring to become a data analyst. It involves mastering tools like Python, SQL, and Excel, as well as understanding statistical concepts and data manipulation techniques. By acquiring these skills, you can unlock numerous opportunities in the field of data analytics. Thank you for watching this video, and I’ll see you in another video.
