In this post, we’ve shared a biostatistics lab report.

Objective of Lab Report

The duration of time from first exposure to HIV infection to AIDS diagnosis is called the incubation period. The incubation periods of a random sample of 7 HIV infected individuals is given below (in years):

12.0 10.5. 9.5 6.3 13.5 12.5 7.2

a. Calculate the sample mean.

b. Calculate the sample median.

c. Represent the data in a simple bar graph using statistical tools

Answer of Question

(a) Mean: (Sum of all values / No of Values) = 71.5/7 = 10.2 years

(b) Median= (n+1 / 2) = (7+1)/2 = Value at 4^th position = 10.5 years 

(c) Excel: 

Minitab:
