Question 6

The process with the highest probability of error is

Answer 6

Pre analytical (46-68%)

Question 7

The process with the least error is

Answer 7

Analytical (7-13%)

Question 8

Post analytical chance is

Answer 8

19-47%

Question 9

What is the mean in the following

3,5,6,9,8,4,3,6,7

Answer 9

Mean = sum of a number
————————-
Total of number

Mean = 3+5+6+9+8+4+3+6+7=51
Total number =9

Therefore mean =51/9=5.667

Question 10

Find the median of this numbers

3,5,6,9,8,4,3,6,7

Answer 10

Median is middle number when arranged

6 is the median

Question 11

Find the mode

3,5,6,9,8,4,3,6,7

Answer 11

Mode is most frequent number

Arrange from smaller to bigger and find the frequent number

=3&6

Question 12

Find the median

5,6,7,8,3,1,7,5,1,1

Answer 12

1,1,1,3,5,5,6,7,7,8

Median = 5+5/2=5

Question 13

How to establish a reference interval

Answer 13

Use a minimum of 120 healthy people

Each lab should establish its own reference interval

Use parametric means to define mean and standard deviation

Define exclusion and inclusion criteria to define a healthy population
