Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

Retraction occurs in the scapula (Shoulder blades) and mandible (jaw). Dorsiflexion you see that happen in your foot. When you bring your toes closer to the shin. Supination is more on the forearm and foot, where you rotate it so your palms are facing forward (sole facing the other ankle for feet). Flexion is the movement of body parts where you bring them closer to each other at a joint (the angle between the two parts are lessened). Like when you bend your elbows to "flex" muscles.
