Two students performed the same experiment, testing how far iodine will diffuse through starchy tissue, such as potatoes. They cut 5 potato squares each, all of equal sizes, and placed them into small cups with iodine solution for 15 minutes. Then they measured how far from the edge of the potato the iodine diffused into the potatoes, in millimeters.

What is the range of Student 1's results?



Answer :

GinnyAnswer
To find the range of Student 1's results, we need to follow these steps:

1. Identify the minimum value: Among Student 1's results, we look for the smallest value.
2. Identify the maximum value: Among Student 1's results, we look for the largest value.
3. Calculate the range: The range is found by subtracting the minimum value from the maximum value.

Let's list Student 1's results first:
- Trial 1: 3.25 mm
- Trial 2: 3.17 mm
- Trial 3: 3.26 mm
- Trial 4: 3.64 mm
- Trial 5: 3.44 mm

1. Identifying the minimum value:
The minimum value among the results is [tex]\( \text{min} = 3.17 \)[/tex] mm.

2. Identifying the maximum value:
The maximum value among the results is [tex]\( \text{max} = 3.64 \)[/tex] mm.

3. Calculating the range:
The range is computed as:
[tex]\[ \text{Range} = \text{max} - \text{min} = 3.64\ \text{mm} - 3.17\ \text{mm} = 0.47\ \text{mm} \][/tex]

Therefore, the range of Student 1's results is [tex]\(0.47\)[/tex] mm.
