Filter on any of the responses that do not say “January” and update them to “January”. To ensure data consistency, it is important to standardize the responses. In this case, the analyst should filter on any responses that do not say “January” and update them to “January” to make sure all responses for the month of January are consistent. This will make it easier to analyze the data and avoid confusion or misinterpretation of the results. The other options (A, B, and D) may not be the best approach as deleting responses, replacing responses with a different value, or sorting and updating the responses may lead to a loss of information or a misinterpretation of the results. It is important to retain as much data as possible while also ensuring that the data is consistent and accurate.
