Hi, all I have a cubing science fair project I am working on. It is due March 21st. If you could solve a couple of cubes for me for my data that would be great. My hypothesis is if the noise level increases, the cubing solve times will not increase. In total I only need you to do 9 2x2 solves so if you would like to help me here is the process:
A few notes before I start:
  1. Please a 2x2 for the duration of the solves
  2. Please use this link for the sound
    :
  3. On youtube please make sure your volume slider is on max so it does not mess up the results
  4. Please don’t use headphones
  5. You can use the input function in cstimer to easily input the scrambles
  6. Please roll a die, if you roll 1 or 2, just proceed as normal. If you roll a 3 or 4, they should do the first set of scrambles at mid-volume, the second set at max, and the third set with no sound. If they roll 5 or 6, they should do the first set at max, the second set with no sound, and the third set at mid volume.
  7. If you don't have a die here is one
  8. If you rolled 1 or 2 use no sound. If you rolled 3 or 4 use low volume (1 click on computer.) If you rolled 5 or 6 use max volume.
    1. Scrambles Set 1
      1. F U2 R' F R2 U2 F R U'
      2. R2 U2 R U F' U2 R F U'
      3. F' U' R' F U' F2 U F2 R' U
  9. If you rolled a 1 or 2 Please solve with the volume on level one (if you rolled 3 or 4 please use max volume) (If you rolled a 5 or 6 please use no sound)
    1. Scrambles Set 2
      1. U R2 U F' R F R2 F R
      2. U2 R' F2 R' F2 U R' F' R'
      3. U R' F U F2 R2 U F' R'

  1. If you rolled 1 or 2 use max volume. If you rolled 3 or 4 use no sound. If you rolled 5 or 6 use low volume (1 click on computer.)
    1. Scrambles Set 3
      1. U2 R2 F2 R F U' F2 U' F'
      2. R2 U2 R F2 U' R' F' R' U2
      3. U2 R' U R' U2 F2 R' U' F'
  2. Please Submit your data like this:
  3. First list whether you are using a keyboard or stackmat timer
  4. Then list your times as follows

Thanks for helping me out! I am really interested and how this will turn out, I will share my results when I am finished. I have always wondered if using earplugs really helps concentration, and hopefully, this test can help settle my question! If you have any questions please ask me and I will do my best to answer them. Also don't hurt your ears doing max sound if it is too loud just turn it down a bit!

4.93+2=6.93
5.64

Mo3 - 5.90

1/3 volume

6.79
8.38
3.16

Mo3 - 6.11

Full volume (which was actually only 30% of the full volume but I don't want to damage my ears)

5.25
2.84
5.31

Mo3 - 4.47

Final comment - I don't think the noise actually affected my times, because a.) I've listened to music during solves before and b.) I've been to comps with quite a bit of noise. I think the differences are just because I have incredibly inconsistent times.
 
Cool thanks, and totally fine about turning sound down for your ears. That is super interesting because I listen to music all the time when I cube, and I found similar times.
 
I have a suggestion to improve your study. Currently, each noise level is associated with a particular set of scrambles, meaning that any results might be because the scrambles were easier or harder. In other words, the scramble quality is a confounding variable. To mitigate this, have each participant roll a die. If they roll 1 or 2, just proceed as normal. If they roll a 3 or 4, they should do the first set of scrambles at mid volume, the second set at max, and the third set with no sound. If they roll 5 or 6, they should do the first set at max, the second set with no sound, and the third set at mid volume. This way, the results for each noise level are independent of the scramble quality of each set, apart from just randomness which should get drowned out with a sufficiently large sample size.

mo3: DNF (4.64) - is there a reason you didn't take ao5s? then things like this wouldn't happen.

I don't really practice 2x2 that much so I warmed up with like 15 solves first. I did this on stackmat. I agree with Dyna in that I don't think the noise really affected the solves. I've been to a bunch of comps and listen to a variety of music when cubing, so I'm used to varying noise levels. I think the whole average is well within a standard distribution of just normal solves, and it would definitely be easier to show that the scrambles caused the fluctuations in time, not the background noise.

I'll give you the benefit of the doubt and assume you're not a troll and simply just don't know how to calculate mo3.
I've done the calculation for you.

I just won first place in my local science fair, thank you to all who helped contribute, to making my project win! It really means a lot to me that yall spent your time working on my project to helo me out.
You owe use 5 bucks now.
I mean, I didn't participate, but you know what I mean...
