๐Ÿ” Real-World Data Analyst Tasks & How to Solve Them

As a Data Analyst, your job isnโ€™t just about writing SQL queries or making dashboardsโ€”itโ€™s about solving business problems using data. Letโ€™s explore some common real-world tasks and how you can handle them like a pro!

๐Ÿ“Œ Task 1: Cleaning Messy Data

Before analyzing data, you need to remove duplicates, handle missing values, and standardize formats.

โœ… Solution (Using Pandas in Python):

import pandas as pd  
df = pd.read_csv('sales_data.csv')
df.drop_duplicates(inplace=True) # Remove duplicate rows
df.fillna(0, inplace=True) # Fill missing values with 0
print(df.head())


๐Ÿ’ก Tip: Always check for inconsistent spellings and incorrect date formats!


๐Ÿ“Œ Task 2: Analyzing Sales Trends

A company wants to know which months have the highest sales.

โœ… Solution (Using SQL):

SELECT MONTH(SaleDate) AS Month, SUM(Quantity * Price) AS Total_Revenue  
FROM Sales
GROUP BY MONTH(SaleDate)
ORDER BY Total_Revenue DESC;


๐Ÿ’ก Tip: Try adding YEAR(SaleDate) to compare yearly trends!


๐Ÿ“Œ Task 3: Creating a Business Dashboard

Your manager asks you to create a dashboard showing revenue by region, top-selling products, and monthly growth.

โœ… Solution (Using Power BI / Tableau):

๐Ÿ‘‰ Add KPI Cards to show total sales & profit

๐Ÿ‘‰ Use a Line Chart for monthly trends

๐Ÿ‘‰ Create a Bar Chart for top-selling products

๐Ÿ‘‰ Use Filters/Slicers for better interactivity

๐Ÿ’ก Tip: Keep your dashboards clean, interactive, and easy to interpret!

ยฉHow fresher can get a job as a data scientist?ยฉ

Job market is highly resistant to hire data scientist as a fresher. Everyone out there asks for at least 2 years of experience, but then the question is where will we get the two years experience from?

The important thing here to build a portfolio. As you are a fresher I would assume you had learnt data science through online courses. They only teach you the basics, the analytical skills required to clean the data and apply machine learning algorithms to them comes only from practice.

Do some real-world data science projects, participate in Kaggle competition. kaggle provides data sets for practice as well. Whatever projects you do, create a GitHub repository for it. Place all your projects there so when a recruiter is looking at your profile they know you have hands-on practice and do know the basics. This will take you a long way.

All the major data science jobs for freshers will only be available through off-campus interviews.

Some companies that hires data scientists are:
Siemens
Accenture
IBM
Cerner

Creating a technical portfolio will showcase the knowledge you have already gained and that is essential while you got out there as a fresher and try to find a data scientist job.
