The correct answer is: A. Data tidying
Data tidying is the process of cleaning and organizing data so that it can be easily analyzed. This involves removing errors, inconsistencies, and missing values, as well as converting the data into a format that is compatible with the analysis tools that will be used.
Data mining is the process of extracting patterns from data. This can be done using a variety of techniques, such as statistical analysis, machine learning, and data visualization.
Data booting is the process of preparing data for analysis by removing outliers and other anomalies. This can be done using a variety of techniques, such as statistical methods, machine learning, and data visualization.
Data tidying is the most important step in the data analysis process, as it ensures that the data is accurate and complete. Without data tidying, the results of the analysis may be unreliable.
Data mining and data booting are also important steps in the data analysis process, but they are not as important as data tidying. Data mining can be used to identify patterns in the data, while data booting can be used to remove outliers and other anomalies. However, these steps cannot be performed if the data is not tidy.
Therefore, the correct answer is: A. Data tidying
