Q
What is Standard Deviation a measure of?
A
Standard Deviation is a measure of how spread out your repeats are from the mean
2
Q
What are the advantages of using SD over the range?
A
- SD shows the spread of data around the mean while the range is only the difference between the highest and lowest value
- SD reduces the effect of anomalies, whereas the range includes anomalies
- SD can indicate whether the difference between results is significant
