Rationale of study
· To determine if the length of a person’s left foot is related to his or her height.
· To justify if the length of a person’s left foot can be used to estimate his or her height.
Hypothesis
a) Research hypothesis:
· There is a positive correlation between the height and length of the left foot of a person.
b) Null hypothesis:
· There is no positive correlation between the height and length of the left foot of a person.

Conceptualization
Height: The vertical distance from the bottom or lowest part of an object or person to the top or apex.
Foot length: A measure of the distance from the heel to the longest toe of the left foot when the subject stands with weight evenly distributed on both feet.
Operationalization
Height will be measured using a measuring tape against a vertical wall in centimetres.
Foot length will be measured with the use of a measuring tape, from the posterior aspect of the calcaneus to the longest toe with participant standing against a box.
