### 2. Processed Datasets

Processed datasets are cleaned and transformed versions of raw data. They have undergone steps such as removing duplicates, handling missing values, and normalizing data ranges. Processed datasets are typically easier to analyze.

### 3. Time Series Datasets

Time series datasets contain observations collected at regular intervals over time. Examples include stock prices, temperature readings, and sales figures. Time series analysis is crucial for forecasting and identifying trends.



Cross-sectional datasets capture observations at a single bahrain number dataset point in time across multiple subjects. For example, a dataset containing the incomes of various households in a city collected during one year is considered cross-sectional.

### 5. Panel Datasets

Panel datasets combine elements of both time series and cross-sectional data. They consist of observations on multiple subjects across multiple time periods. For instance, tracking the annual income of the same households over several years forms a panel dataset.

## Sources of Number Datasets

Number datasets can be sourced from various platforms and methods, including:

### 1. Public Repositories

Many government and educational institutions provide access to public datasets. Examples include:

- **Kaggle**: A platform for data science competitions that also hosts numerous datasets.
- **UCI Machine Learning Repository**: A collection of datasets for machine learning research.
- **Government Open Data**: Many governments publish datasets on topics such as health, economy, and environment.
