   Course Detail

Understanding statistics is fundamental to understanding what a diagnostic test result means and to be able to explain it clearly to the person being assessed. Quantitative data is a fundamental component of all full diagnostic reports and if a diagnosis is to be fully supported then it is essential that all data is calculated and reported with utmost accuracy.

The course will cover:

  • What is a standardised test?
  • Understanding the normal distribution of a population – the normal distribution curve.
  • Ways of measuring a population distribution
    • Descriptive statistics
    • Standard deviation
    • Standard scores
    • Percentiles
    • Scaled scores
    • Descriptors – what does average mean
  • Converting between scores
  • Understanding accuracy – significance, standard error and probability ranges
  • Composite scores and indexes – when to use and when to exclude
  • Visualising data to help understanding.

The course will use examples from the SDMT, TOMAL-2 and the WRIT. It will be helpful to have the manuals for these tests available but not essential.
