What are the factors to consider when cleaning the data? Please seelct all that apply. Screener Straighterliner Attention check Completion date Incomplete data

When cleaning data, there are several factors to consider:

1. Screener: This refers to the initial screening of the data. You need to check if the data makes sense, if it's in the right format, and if it's relevant to your study or project.

2. Straighterliner: This term is not typically used in data cleaning. It might be a specific term related to the data you're working with, or it could be a typo. You would need more context to determine how to handle this during data cleaning.

3. Attention check: This is a method used in surveys to ensure that the respondent is paying attention and not randomly answering questions. If your data includes attention checks, you'll need to decide how to handle responses that failed these checks - typically, they would be excluded from the analysis.

4. Completion date: This could be important if the data was collected over a long period of time and conditions may have changed. You might need to consider whether the date of completion could impact the results and how to handle this in your analysis.

5. Incomplete data: This is a common issue in data cleaning. You'll need to decide how to handle missing or incomplete data - whether to exclude it, fill it in with estimated values, or use some other method. This decision can significantly impact your results, so it's important to carefully consider your approach.

So, all the options apply except for "Straighterliner" unless given more context about what it means in your specific project.
