The correct answer is D. None of the mentioned.
Data analysis is a process of inspecting, cleaning, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains.
The data analysis process is often described as consisting of the following steps:
- Obtain the data. This involves identifying the data that is needed, gathering it from the appropriate sources, and ensuring that it is in a format that can be analyzed.
- Clean the data. This involves removing any errors or inconsistencies in the data.
- Exploratory data analysis (EDA). This involves exploring the data to get a better understanding of its characteristics.
- Data modeling. This involves building a model that can be used to make predictions or inferences about the data.
- Evaluation. This involves assessing the accuracy and usefulness of the model.
- Communication. This involves communicating the results of the analysis to stakeholders.
The steps involved in data analysis can vary depending on the specific goals of the analysis. However, the general steps outlined above are common to most data analysis projects.
In the question, A, B, and C are all steps in data analysis. Option D is not a step in data analysis.
