BIOSTATISTICS
Take Home Exam
A total of 20 volunteer patients were given different types of diet (A, B, C, and D). The blood
sugar level of each volunteer was taken before the experiment. The blood sugar after each diet was also
determined. Other data were taken such as gender, age, weight and wake hours. Using MS Excel and
SPSS, perform the necessary statistical test to answer the following problems:
a. Make a graphical representation of the gender of the patients (pie).
b. Make a bar graph of the age of the patients.
c. Is there a significant difference between the initial blood sugar level of males and females?
d. Is there a significant difference on the CHANGE in blood sugar level among the diets from the initial
blood sugar level? Compare means using DMRT.
e. Is there a correlation between:
e.1 gender and weight
e.2 gender and wake hours
e.3 gender and initial blood sugar
e.4 wake hours and initial blood sugar
e.5 age and wake hours
