3d- Pilot study

Question 1

A pilot study is integral to the development of an investigation, but what is it used for?

Answer 1

To help plan procedures, assess validity and check techniques

Question 2

What does a pilot study allow for?

Answer 2

The evaluation and modification of experimental design

Question 3

What can a pilot study ensure?

Answer 3

An appropriate range of variables in the independent variable is chosen and tells the investigator how many repeat measurements are required to give a representative value for each independent data point

Question 4

What do the following terms mean:

• validity
• reliability
• accuracy
• precision

Answer 4

Validity= variables controlled so that any measured effect is likely to be due to the independent variable
Reliability= consistent values in repeats and independent replicates
Accuracy= data, and means of data sets, are close to the true value
Precision= measured values are close to each other
