Unit 3 - Topic 2 - Experimentation - Section A - Pilot Study Flashcards
1
Q
What is validity
A
Variables controlled so that any measured effect is likely to be due to the independent variable
2
Q
What is reliability
A
Consistent values in repeats and independent replicates
3
Q
What is accuracy
A
Data, or means of data sets, are close to the true value.
4
Q
What is precision
A
Measured values are close to each other
5
Q
What is a pilot study
A
Is used to help plan procedures, assess validity and check techniques
6
Q
What does a pilot study allow
A
Evaluation and modification of experimental design
7
Q
What can the use of a pilot study ensure
A
An appropriate range of values for the independent variable. It allows the investigator to establish the number of repeat measurements required to give a representative value for each independent datum point
