Missing data

Missing data is a common problem in research, and it can occur for a variety of reasons. Some data may be missing because it was not collected in the first place, while other data may be missing because it was lost or destroyed. Missing data can pose a serious challenge to researchers, as it can bias the results of a study and make it difficult to draw valid conclusions.

Methods for handling missing data
There are a variety of methods for handling missing data, and the best method to use will depend on the specific circumstances of the study. Some common methods include:
- Deletion: This involves simply deleting the cases with missing data from the analysis.
- Imputation: This involves estimating the missing values based on the available data.
- Multiple imputation: This involves creating multiple plausible datasets by imputing the missing values multiple times. The results of the analysis are then combined to produce a final estimate.
