Data is the information collected through research. It can include written information, numbers, sounds and pictures.
Data analysis involves examining and processing research data, in order to answer the questions that the project is trying to address. It involves identifying patterns and drawing out the main themes, and is often done with specialist computer software.
All personal information is protected in the UK by the Data Protection Act 2018. This means that researchers have to put in all the necessary safeguards to protect the confidentiality of the information they collect about research participants. They should explain in the patient information sheet: how the participants’ data will be collected, how it will be stored securely, what it will be used for, who will have access to the data that identifies participants, how long it will be kept and how it will be disposed of securely.
A diagnostic test is an indicator or predictor of an illness state. As such, the term needs to be interpreted broadly as it includes diagnostic tests, screening, tests to stage disease, treatment monitoring, and estimate prognosis estimation.
