Question

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?

Answer 1

The average diffusion distance is 2.1 mm

Step-by-step explanation:

Given

Diffusion distance of the four potato squares are;

`Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm`

Required

Average Diffusion Distance

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

Mean is calculated as thus;

`Mean = (\sum x)/(n)`

Where x is the individual distance of the potato squares

`\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm`

`\sum x = 8.4mm`

n is the number of potato squares

n = 4

`Mean = (\sum x)/(n)`

`Mean = (8.4 mm)/(4)`

`Mean = 2.1 mm`

Hence, the average diffusion distance is 2.1mm
