Data analytics is the art and science of drawing actionable insights from data.
Data Analytics + Business Knowledge = Impact/Value Creation for the Business
Overall, if you understand your business administration and have the capability to perform exploratory data analysis to gather the required information, then you are good to go with a career in data analytics.
When I started learning data analytics, I literally didn’t know anything. So, I am creating this blog for students like me. I also welcome professionals and seniors to correct me if I miss anything or write something incorrectly.
EDA (Exploratory Data Analysis) plays a crucial role in data analytics—like tea without sugar, it’s essential! ??
1. Data Cleaning: Missing values, duplicates, and data formatting ko theek karna.
2. Data Visualization: Graphs (like histograms, scatter plots, bar charts) ke zariye patterns aur trends ko samajhna.
3. Statistical Analysis: Basic statistics (mean, median, mode, variance) calculate karna.
4. Correlation Analysis: Variables ke beech relationship ko check karna.
5. Outliers Detection: Unusual data points ko identify karna jo analysis ko impact kar sakte hain.
In short, EDA ka maksad data ko samajhna aur insights nikalna hota hai.

Why Study Data Analytics?
Studying data analytics helps in making data-driven decisions, understanding trends, and improving business strategies.
Data-Driven ka matlab hai, decisions aur strategies ko data aur facts ke basis par banana, na ki intuition ya guesswork par.
Example: Ek company jo data-driven approach follow karti hai, woh sales data ka analysis karke customer preferences aur buying patterns samajh kar marketing strategies design karti hai, jisse sales aur customer satisfaction improve hoti hai.
Data Visualization for Decision Making
- Definition: Data visualization refers to presenting data graphically through charts, graphs, and maps, making complex data easier to understand and analyze.
- Importance: It helps in spotting trends, patterns, and outliers in data, enabling better insights and data-driven decisions.
- Tools and Technologies: Essential for handling large datasets. Examples include Plotly, DataHero, Tableau, Dygraphs, QlikView, and ZingChart.
- Types of Visualizations:
- Charts: Display data visually (e.g., bar charts, pie charts).
- Tables: Organize data in rows and columns.
- Graphs: Show relationships between variables (e.g., line graphs, scatter plots).
- Maps: Visualize geographic data.
- Dashboards: Combine visualizations into a single view.
- Applications: Key for big data processing, creating service management dashboards, and supporting analysis and design in various sectors.
Data visualization turns raw data into actionable insights, making it crucial in the data analytics process.
