1. What are the ways to detect outliers?
Outliers are detected using two methods:
Box Plot Method: According to this method, the value is considered an outlier if it exceeds or falls below 1.5*IQR (interquartile range), that is, if it lies above the top quartile (Q3) or below the bottom quartile (Q1).
Standard Deviation Method: According to this method, an outlier is defined as a value that is greater or lower than the mean ยฑ (3*standard deviation).
2. What is a Recursive Stored Procedure?
A stored procedure that calls itself until a boundary condition is reached, is called a recursive stored procedure. This recursive function helps the programmers to deploy the same set of code several times as and when required.
3. What is the shortcut to add a filter to a table in EXCEL?
The filter mechanism is used when you want to display only specific data from the entire dataset. By doing so, there is no change being made to the data. The shortcut to add a filter to a table is Ctrl+Shift+L.
4. What is DAX in Power BI?
DAX stands for Data Analysis Expressions. It's a collection of functions, operators, and constants used in formulas to calculate and return values. In other words, it helps you create new info from data you already have.

๐ Real-World Data Analyst Tasks & How to Solve Them
As a Data Analyst, your job isnโt just about writing SQL queries or making dashboardsโitโs about solving business problems using data. Letโs explore some common real-world tasks and how you can handle them like a pro!
๐ Task 1: Cleaning Messy Data
Before analyzing data, you need to remove duplicates, handle missing values, and standardize formats.
โ Solution (Using Pandas in Python):
๐ก Tip: Always check for inconsistent spellings and incorrect date formats!
๐ Task 2: Analyzing Sales Trends
A company wants to know which months have the highest sales.
โ Solution (Using SQL):
๐ก Tip: Try adding YEAR(SaleDate) to compare yearly trends!
๐ Task 3: Creating a Business Dashboard
Your manager asks you to create a dashboard showing revenue by region, top-selling products, and monthly growth.
โ Solution (Using Power BI / Tableau):
๐ Add KPI Cards to show total sales & profit

๐ Task 1: Cleaning Messy Data
Before analyzing data, you need to remove duplicates, handle missing values, and standardize formats.
โ 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())
๐ก Tip: Always check for inconsistent spellings and incorrect date formats!
๐ Task 2: Analyzing Sales Trends
A company wants to know which months have the highest sales.
โ 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;
