Question

What are the typical steps taken during data wrangling?

1) Data collection and assessment
2) Data cleaning and preprocessing
3) Data transformation and integration
4) Data analysis and visualization

Answer 1

Data wrangling involves data collection and assessment, data cleaning and preprocessing, data transformation and integration, and data analysis and visualization.

Step-by-step explanation:

Data wrangling typically involves several steps:

1. Data collection and assessment: This step involves gathering data from various sources and evaluating its quality, completeness, and relevance.
2. Data cleaning and preprocessing: In this step, the collected data is cleaned by removing irrelevant or duplicate entries and correcting any errors or inconsistencies. It is also preprocessed to transform it into a suitable format for analysis.
3. Data transformation and integration: Here, the data is transformed and combined from different sources to create a unified dataset. This may involve merging, joining, or aggregating data.
4. Data analysis and visualization: Finally, the transformed and integrated data is analyzed using statistical techniques and visualized to gain insights and communicate findings effectively.

Each step is crucial for ensuring the quality and accuracy of the data and ultimately facilitating meaningful analysis and interpretation.
