A student working on their science experiment places four potato squares into solutions of Iodine and measures how far the Iodine diffuses into the potato. The measurements are: 2.1 mm, 1.8 mm, 2.3 mm, and 2.2 mm. What is the average diffusion distance?

The average diffusion distance is 2.1 mm

Explanation:

Given

Diffusion distance of the four potato squares are;

Required

Average Diffusion Distance

To calculate the average diffusion distance; we simply calculate the mean of the student recordings

Mean is calculated as thus;

Where x is the individual distance of the potato squares

n is the number of potato squares

n = 4

Hence, the average diffusion distance is 2.1mm
