  • What is the difference between nominal, ordinal, continue and discrete?

    Nominal = cannot be ordened
    Ordinal = can be ordened
    Continue = all numbers (with decimal)
    Discrete = only whole numbers
  • What characteristics can be used for numerical data?

    Mean, SD, quantiles (25-75%)
  • On which (mean, SD, quantiles, median) do outliers have a large influence?

    Mean and SD
    Quantiles and median are not sensitive
  • What is the difference between SD and SE?

    SE is the variation of the mean
    SD is the variation of single measurements
  • How is the confidence interval calculated?

    Mean +- 1.96*SE
    --> 95% confidence interval (alpha level of 5%)

  • There are some requirements for a database regarding to data protection and management, which?

    1. Audit trail - the database system logs what data was entered, modified and deleted when and by whom (what, when, who)
    2. Information security - access to the data can be arranged. Think of: who can access (which parts of) the data
    3. Dictionary - the database system includes a definition of variables, data formats (text, numeric, date etc.), coding of answer categories (1=yes, 0=no), missing value codes etc. 
    4. Structure - the data can be stored in multiple tables and the relations between tables are defined
  • What is explicit data? And implicit?

    Explicit = any information a consumer actively provides on their own (name, mail adress etc)
    Implicit = information that is not provided intentionally but gathered from available data streams (e.g., information provided by browsing)
  • Which data management system is used within the LUMC?

    Castor (adheres to all requirements)
  • 1.3.2 Design of experiment

  • How do you design an experiment?

    1. Formulate research question
    2. What is the study design (RCT, cross over etc)
    3. What is the sample size, experimental control etc.
  • What statistical test can be used to analyze data from a CRD?

    T-test (2 groups)
    one-way ANOVE (>2 groups)
