Foot problems in men and womenFeatured science projectScience project video


The materials required for the experiment:

-    A survey form on feet disorders
-    writing materials



1.    For this experiment, the independent variable is the gender of the participants. The dependent variable is the types of foot problems the participants suffer from. This is determined by asking them to fill in a survey form. The constants (control variables) are the number of questions asked and the age group of the participants.

Foot problems survey
Name Age Gender Tick one of the following
No Condition Yes No
1 Heel pain    
2 Blisters    
3 Corn    
4 Ingrown toe nail    
5 Bunions    
6 Toenail Fungus    
7 Hammertoes    
8 Achilles tendon    

2.    Prepare a survey form listing several types of common foot-related problems. An example of the survey form is shown above. Add more foot-related conditions to the survey form as needed. Make as many copies of the survey form as required.

3.    With the help of a few volunteers, survey at least 100 females and 100 men on their foot disorders. They can be students, professionals, housekeepers, farmers and people with other, diverse lifestyles.

4.    After collecting all the feedback from the participants, separate and count the number of surveys completed by respondents of each gender. Count the number of males and females suffering from each foot condition as listed in the survey. Next, calculate the proportion of respondents of each gender suffering from each foot problem, as follows:

Percentage of male respondents suffering from foot problem = No. of males suffering from foot problem / Total number of males; or

Percentage of female respondents suffering from foot problem = No. of females suffering from foot problem / Total number of females

Record the results in a table, as shown below.
