Data analytics is the process of examining large sets of data to uncover hidden patterns, correlations, trends, and insights that can inform decision-making and drive business strategies.
- Python
- SQL
- MS Excel
- ML and AI and many more depending upon the type of data
-
Data Collection: Gathering relevant data from various sources, which may include databases, APIs, files, or streaming sources.
-
Data Cleaning: Preprocessing the collected data to handle missing values, outliers, duplicates, and inconsistencies, ensuring data quality and integrity.
-
Data Exploration: Exploring the dataset to understand its structure, characteristics, and relationships between variables through statistical summaries, visualizations, and ** exploratory data analysis (EDA)**.
-
Data Preparation: Transforming and reshaping the data into a suitable format for analysis, which may involve feature engineering, normalization, encoding categorical variables, and splitting the dataset into training and testing sets.
-
Data Analysis: Applying statistical techniques, machine learning algorithms, or other analytical methods to extract meaningful insights, patterns, and trends from the data.
-
Data Visualization: Presenting the analysis results visually using charts, graphs, and dashboards to facilitate understanding and interpretation by stakeholders.
-
Interpretation and Communication: Interpreting the analytical findings in the context of the problem domain, drawing actionable insights, and communicating the results effectively to stakeholders through reports, presentations, or interactive tools.
-
Iteration and Improvement: Iteratively refining the analysis based on feedback, incorporating new data, adjusting models or assumptions, and continuously improving the analytics process to drive better decision-making and outcomes.
I personally started with learning python, I already know other languages like java , javascript and I also work with DSA since I am a developer so I already know logics I wanted to get to know the syntax and flow so I started with this playlist in youtube here
- I installed latest version of python on my windows system with windows 11 pro, no need to set environment variable. I just need to make sure that my system had python in it. I used this tutorial download python
- Check if it is installed or not by typing this command in cmd or terminal
python --version- Next up I downloaded Anaconda navigator to use jupyter notebook. I could have downloaded jupyter only but anaconda navigator is useful in using and launching other libraries and notebooks too.I used this tutorial.
