## Homework Statement

I have this lab report due to tomorrow, but I'm stuck in this problem. My teacher asked me to find the uncertainty for the values, max+min/2. But, i get a huge number, how can that be the uncertainty?

## Homework Equations

1- 154g 110 115 120

2- 208g 116 117 117

3- 137g 107 108 107

4- 145g 119 119 118

5- 155g 118 117 117

6- 149g 115 115 115

Those are my results for my experiment. 1,2,3 etc represent the blocks, and the numbers are the recording in decibel (dbl) sound recorder.

## The Attempt at a Solution

If I do it according to her. Max+min/2 i should get for nr1. 120+110/2=115 ? is that ±115? How can that be the uncertainty? I also attempted to do Max-min/2 for nr1= 120-110/2= 5 so is that ±5?
