Powder Papers
A pharmacist received a prescription for a patient
with rheumatoid arthritis calling for eight divided
powders. The contents of which were to weigh 1
gram. To check his skill, he removed the contents
from each paper after filling the prescription by
the block and divide method. Then each of the
divided powders were weighed as: 1.05, 0.89,
0.98, 1.02, 1.01, 0.94, 1.03 and 0.99. Compute for
the mean, mean deviation, standard deviation.
Interpret the mean as accurate or precise.
Please follow the general guidelines in our
calculations and entering the answers via short
answer.
1. What is the value of N?
2. What is the summation of the values of x?
3. What is the computed arithmetic mean?
4. Is the computed arithmetic mean accurate or
precise?
5. From the computed arithmetic mean, what will
be the computed percentage error?
6. What is the summation of the differences of the
values of x?
7. What is the computed mean deviation?
8. What is the summation of the square of the
differences of the values of x?
9. What will be the denominator used in the
formula in the computation for the standard
deviation in this activity? A. N /B. N-1
10. What is the computed standard deviation?
