The collection, transformation, and organization of data to draw conclusions make predictions for the future and make informed data-driven decisions is called Data Analysis. The profession that handles data analysis is called a Data Analyst. There is a huge demand for Data Analysts as the data is expanding rapidly nowadays. Data Analysis is used to...
Define the Problem or Research QuestionCollect DataData CleaningAnalyzing the DataIn the first step of process the data analyst is given a problem/business task. The analyst has to understand the task and the stakeholder’s expectations for the solution. A stakeholder is a person that has invested their money and resources to a project. The analyst must be able to ask different questions in order to find the right solution to the...
The second step is to Prepare or Collect the Data. This step includes collecting data and storing it for further analysis. The analyst has to collect the data based on the task given from multiple sources. The data has to be collected from various sources, internal or external sources. Internal data is the data available in the organization that yo...
The third step is Clean and Process Data. After the data is collected from multiple sources, it is time to clean the data. Clean data means data that is free from misspellings, redundancies, and irrelevance. Clean data largely depends on data integrity. There might be duplicate data or the data might not be in a format, therefore the unnecessary da...
The fourth step is to Analyze. The cleaned data is used for analyzing and identifying trends. It also performs calculations and combines data for better results. The tools used for performing calculations are Excel or SQL. These tools provide in-built functions to perform calculations or sample code is written in SQL to perform calculations. Using ...
The fifth step is visualizing the data. Nothing is more compelling than a visualization. The data now transformed has to be made into a visual (chart, graph). The reason for making data visualizations is that there might be people, mostly stakeholders that are non-technical. Visualizations are made for a simple understanding of complex data. Tablea...
Presenting the data involves transforming raw information into a format that is easily comprehensible and meaningful for various stakeholders. This process encompasses the creation of visual representations, such as charts, graphs, and tables, to effectively communicate patterns, trends, and insights gleaned from the data analysis. The goal is to f...
In conclusion, the data analysis processes the ability to distill complex information into clear, visual narratives empowers organizations to make informed decisions. Data-driven insights, effectively communicated, play a pivotal role in addressing business challenges and fostering continual improvement across various domains.

Mar 25, 2024 · Data analysis is the systematic process of inspecting, cleaning, transforming, and modeling data to uncover meaningful insights, support decision-making, and solve specific problems.
- Step one: Defining the question. The first step in any data analysis process is to define your objective. In data analytics jargon, this is sometimes called the ‘problem statement’.
- Step two: Collecting the data. Once you’ve established your objective, you’ll need to create a strategy for collecting and aggregating the appropriate data.
- Step three: Cleaning the data. Once you’ve collected your data, the next step is to get it ready for analysis. This means cleaning, or ‘scrubbing’ it, and is crucial in making sure that you’re working with high-quality data.
- Step four: Analyzing the data. Finally, you’ve cleaned your data. Now comes the fun bit—analyzing it! The type of data analysis you carry out largely depends on what your goal is.
- Define a specific objective. The initial phase of any data analysis process is to define the specific objective of the analysis.
- Data collection. Once the objective has been defined, it is time to design a plan to obtain and consolidate the necessary data.
- Data cleaning. Once we have collected the data we need, we need to prepare it for analysis. This involves a process known as data cleaning or consolidation, which is essential to ensure that the data we are working with is of quality.
- Data analysis. Once the data has been cleaned and prepared, it is time to dive into the most exciting phase of the process, data analysis.
