It is a great place to start when exploring and analyzing data, and it has powerful data cleansing, organizing, and manipulation tools, such as filtering, sorting, and removing duplicates.
Discover important functions and formulas, such as text functions (LEFT, RIGHT, CONCATENATE), logical functions (IF, AND, OR), statistical functions (AVERAGE, MEDIAN, STANDARD DEVIATION), and lookup functions (VLOOKUP, INDEX MATCH). You should also learn how to handle missing values, eliminate duplicates, format data consistently, and identify trends with conditional formatting.
Step 3: Working on Data with Power BI
Data scientists have access to numerous sophisticated data visualization choices with Power BI. Among these features include smooth integration with other Microsoft products, such Excel and Azure, which facilitates team collaboration and dashboard sharing. With Power BI, you can create engaging data stories that can be used to reveal hidden trends, find correlations, or share findings with stakeholders.
Next, investigate Power BI’s formula language, DAX, which allows you to perform calculations and modify data right within your visualizations. With DAX, you can build trustworthy data models that connect and manage connections between numerous data sources. Get even more inventive with the variety of visualization options available to tailor your findings for certain audiences.
Step 4: Start with Python Programming
It is no coincidence that Python has emerged as the dominant language in data science. It is perfect for revealing hidden meanings in data because of its versatility, strength, and simplicity of usage.
A diverse ecosystem of data science libraries, including scikit-learn, Pandas, and NumPy, provides pre-built tools for data manipulation, analysis, and machine learning. Gaining proficiency in Python programming opens up a wide range of career advancement opportunities and makes it simple to enter the data science field.
Additionally, Python seamlessly integrates with other well-known data science tools, like Jupyter Notebooks and SQL databases, making the process more efficient. To begin, learn the fundamentals of Python, such as lists, tuples, and dictionaries, which form the basis for increasingly complex tasks. Next, look at Pandas, a helpful framework for data selection, cleaning, aggregation, and filtering. NumPy provides powerful tools for numerical operations and calculations on big datasets, including linear system solution and matrix multiplication. Lastly, try out visualization tools like Matplotlib and Seaborn to produce engaging data stories.
