2. **Imputation**: Fill in missing values using techniques like mean, median, mode, or more advanced methods like KNN or regression.
3. **Flagging**: Create a new column to indicate missing values for analysis.
4. **Predictive Modeling**: Use algorithms to predict and fill in missing values based on other data.
5. **Leave as Is**: In some cases, you may choose to leave missing values if they are meaningful for analysis.
Ques:- What are the steps involved in data cleaning
Right Answer:
1. Remove duplicates
2. Handle missing values
3. Correct inconsistencies
4. Standardize formats
5. Filter out irrelevant data
6. Validate data accuracy

Ques:- What is regression analysis and when is it used
Right Answer:
Regression analysis is a statistical method used to examine the relationship between one dependent variable and one or more independent variables. It is used to predict outcomes, identify trends, and understand the strength of relationships in data.
Ques:- What is data normalization and why is it important
Right Answer:
Data normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves structuring the data into tables and defining relationships between them. Normalization is important because it helps eliminate duplicate data, ensures data consistency, and makes it easier to maintain and update the database.
Ques:- What is classification analysis and how does it work
Right Answer:
Classification analysis is a data analysis technique used to categorize data into predefined classes or groups. It works by using algorithms to learn from a training dataset, where the outcomes are known, and then applying this learned model to classify new, unseen data based on its features. Common algorithms include decision trees, logistic regression, and support vector machines.
Ques:- Given Data for doing different formats like pivot, and matching the data for another data
Right Answer:
To analyze data for different formats like pivot tables and matching datasets, you should:

1. **Identify Key Variables**: Determine the key fields that will be used for matching and pivoting.
2. **Clean the Data**: Ensure that the data is free from duplicates, errors, and inconsistencies.
3. **Use Pivot Tables**: Create pivot tables to summarize and analyze the data by aggregating values based on categories.
4. **Match Data**: Use functions like VLOOKUP or JOIN operations in SQL to match data from different sources based on the identified key variables.
5. **Validate Results**: Check the accuracy of the matched data and the pivot table outputs to ensure they meet business requirements.
