We treated different seeds with different kinds of sounds.
We wanted to test the effects of sounds in the length and weight of the seed after treatment.
The experiment was under 14 days.
The seeds were grown for 7 days without any exposure to any sounds. The next 7 days, there were already sounds.
I want to know if there is significant difference between the different treatments.
I'm trying to review again my stat right now.
This was a surprise so I ask you guys. I really need your help.
@kevinishappy,
You want to test two populations that you expect to each be normally distrubuted. Standard t-test should work well here.
@engineer,
Thank you very much sir with that. From that, I could compare those treated with sound with those that are not. However, is there also a statistical method that could check if there is a significant difference among the different sound treatments (normal, classical and rock)?
@kevinishappy,
You can still use the same approach. Compare each to the control (no sound), then if you find a difference, you can compare them to each other.
Stumble It!
