Services are available for researchers who collect audio recorded data that need to be transcribed from an audio file to a text file. When you come across missing data, let your faculty researcher know and consider meeting with Roger Brown ( in the School of Nursing Research Office to discuss the best way to handle the missing data in your statistical analyses What to do with missing data is more complicated that you’d expect – you need to determine whether the data are missing at random or not at random because this will have significant effects on your data analysis, therefore your findings. Missing data can occur for many reasons, the most common is that participants choose not to answer a question. If the participant completes the survey for all waves except the third, the researcher would have a missing case. For missing cases, consider the situation where a participant is enrolled in a 10-year longitudinal study where they are asked to complete a survey once every two years (five waves – once every two years over 10 years). If a participant completing a survey chooses not to answer a question or if the answer for a question does not get recorded, this is an example of a missing value. Missing data are values for variables that were not collected from a study participant whereas missing cases are values for entire sets of variables that were not collected from a participant. There are two categories of missing data, missing values and missing cases. Missing data – What it is and what to do when you find it ![]() Example of a de-identified participant recruitment tracking table (excel file) Information included will be tailored to each study but may include contact dates and methods, eligibility, participation (or opted out), receipt of materials (informed consent), completion of study phases, and other key data. These tables are used to track research participants over the course of a study.
