Common Data Cleaning Techniques for Data Analysts Remove Duplicates: Purpose: Eliminate repeated rows to maintain unique data. Example: SELECT DISTINCT column_name FROM table; Handle Missing Values: Purpose: Fill, remove, or impute missing data. Example: Remove: df.dropna() (in Python/Pandas) Fill: df.fillna(0) Standardize Data: Purpose: Convert data to a consistent format (e.g., dates, numbers). Example: Convert text to lowercase: df['column'] = df['column'].str.lower() Remove Outliers: Purpose: Identify and remove extreme values. Example: df = df[df['column'] < threshold] Correct Data Types: Purpose: Ensure columns have the correct data type (e.g., dates as datetime, numeric values as integers). Example: df['date'] = pd.to_datetime(df['date']) Normalize Data: Purpose: Scale numerical data to a standard range (0 to 1). Example: from sklearn.preprocessing import MinMaxScaler; df['scaled'] = MinMaxScaler().fit_transform(df[['column']]) Data Transformation: Purpose: Transform or aggregate data for better analysis (e.g., log transformations, aggregating columns). Example: Apply log transformation: df['log_column'] = np.log(df['column'] + 1) Handle Categorical Data: Purpose: Convert categorical data into numerical data using encoding techniques. Example: df['encoded_column'] = pd.get_dummies(df['category_column']) Impute Missing Values: Purpose: Fill missing values with a meaningful value (e.g., mean, median, or a specific value). Example: df['column'] = df['column'].fillna(df['column'].mean()) I have curated best 80+ top-notch Data Analytics Resources 👇👇 https://whatsapp.com/channel/0029VaGgzAk72WTmQFERKh02 Like this post for more content like this 👍♥️ Share with credits: https://t.me/sqlspecialist Hope it helps :)

SQL Basics for Beginners: Must-Know Concepts 1. What is SQL? SQL (Structured Query Language) is a standard language used to communicate with databases. It allows you to query, update, and manage relational databases by writing simple or complex queries. 2. SQL Syntax SQL is written using statements, which consist of keywords like SELECT, FROM, WHERE, etc., to perform operations on the data. - SQL keywords are not case-sensitive, but it's common to write them in uppercase (e.g., SELECT, FROM). 3. SQL Data Types Databases store data in different formats. The most common data types are: - INT (Integer): For whole numbers. - VARCHAR(n) or TEXT: For storing text data. - DATE: For dates. - DECIMAL: For precise decimal values, often used in financial calculations. 4. Basic SQL Queries Here are some fundamental SQL operations: - SELECT Statement: Used to retrieve data from a database.

     SELECT column1, column2 FROM table_name;
     

- WHERE Clause: Filters data based on conditions.

     SELECT * FROM table_name WHERE condition;
     

- ORDER BY: Sorts data in ascending (ASC) or descending (DESC) order.

     SELECT column1, column2 FROM table_name ORDER BY column1 ASC;
     

- LIMIT: Limits the number of rows returned.

     SELECT * FROM table_name LIMIT 5;
     

5. Filtering Data with WHERE Clause The WHERE clause helps you filter data based on a condition:

   SELECT * FROM employees WHERE salary > 50000;
   

You can use comparison operators like: - =: Equal to - >: Greater than - <: Less than - LIKE: For pattern matching 6. Aggregating Data SQL provides functions to summarize or aggregate data: - COUNT(): Counts the number of rows.

     SELECT COUNT(*) FROM table_name;
     

- SUM(): Adds up values in a column.

     SELECT SUM(salary) FROM employees;
     

- AVG(): Calculates the average value.

     SELECT AVG(salary) FROM employees;
     

- GROUP BY: Groups rows that have the same values into summary rows.

     SELECT department, AVG(salary) FROM employees GROUP BY department;
     

7. Joins in SQL Joins combine data from two or more tables: - INNER JOIN: Retrieves records with matching values in both tables.

     SELECT employees.name, departments.department
     FROM employees
     INNER JOIN departments
     ON employees.department_id = departments.id;
     

- LEFT JOIN: Retrieves all records from the left table and matched records from the right table.

     SELECT employees.name, departments.department
     FROM employees
     LEFT JOIN departments
     ON employees.department_id = departments.id;
     

8. Inserting Data To add new data to a table, you use the INSERT INTO statement:

   INSERT INTO employees (name, position, salary) VALUES ('John Doe', 'Analyst', 60000);
   

9. Updating Data You can update existing data in a table using the UPDATE statement:

   UPDATE employees SET salary = 65000 WHERE name = 'John Doe';
   

10. Deleting Data To remove data from a table, use the DELETE statement:

    DELETE FROM employees WHERE name = 'John Doe';
