Suggested answer to exercise: Standard deviation of serum triglyceride data, 2

Question 2: Report these to two decimal places.

Suggested answer

We have:

Mean = 0.5059
Standard deviation = 0.21914
Variance = 0.048

To two decimal places these are:

Mean = 0.51 mmol/L
Standard deviation = 0.22 mmol/L
Variance = 0.05 mmol/L

In each case, the third decimal place is 5 or more, so we round up.
