Pilot study and definitions Flashcards
What is reliability definition
Consistent values are achieved in repeats and independent replicates
What is validity definition
Variables controlled so that any measured effect is likely to be due to the independent variable
What is accuracy definition
Data, or means of data sets are close to the true value
What is precision definition
Measured values are close to each other
What’s a pilot study definition
Pilot studies are small scale, preliminary studies which aim to investigate whether crucial components of a main study will be feasible
What do pilot studies help to do
Help to plan procedures and assess validity and check techniques
What do pilot studies allow
-Evaluation and modification of experimental design.
-Ensure you have appropriate range of values for the independent variable
-Allows investigators to establish the number of repeat measurements required to give a representative value for each independent datum point.
