Pilot study and definitions

Question 1

What is reliability definition

Answer 1

Consistent values are achieved in repeats and independent replicates

Question 2

What is validity definition

Answer 2

Variables controlled so that any measured effect is likely to be due to the independent variable

Question 3

What is accuracy definition

Answer 3

Data, or means of data sets are close to the true value

Question 4

What is precision definition

Answer 4

Measured values are close to each other

Question 5

What’s a pilot study definition

Answer 5

Pilot studies are small scale, preliminary studies which aim to investigate whether crucial components of a main study will be feasible

Question 6

What do pilot studies help to do

Answer 6

Help to plan procedures and assess validity and check techniques

Question 7

What do pilot studies allow

Answer 7

-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.
