Which statistical test for germination
Vicky Palami posted a topic in Biology and ESShey everyone. I´m almost done with my bio IA. It´s about the effect of coffee on the germination rate of bean seeds. I feel that it was a pretty simple experiment. I had 5 different containers. 10 seeds in each one, with different concentrations of coffee (I watered them with it), with one control group. The dependant variable was the days it took the seeds to germinate. The problem tthat I have is that I don´t know which statistical test I should use for the analysis. I did the ANOVA test but the result seemed...off. I don´t know if that was because ANOVA is not the right tool to use fo

IA MATH SL IA helpI'm doing my math IA on comparing growth of other animals compared to humans because humans reach maturity a lot later than other animals, so I thought it would be interesting. Unfortunately, I really don't know where to go from there, and my rough draft is due Tuesday. I figured I could do exponential curves and compare them, but that's definitely not enough math. Or maybe I could find a logarithmic function from them? But I don't know how I could compare them. Another thing is my other animal is a golden retrievers because I thought it would be easy to find data, but all I found was this htt
IA IA Studies Draft due tomorrow
Josie W posted a topic in Maths StudiesHey guys, Draft of my IA due tomorrow - I have just over 12 hours and have barely any words on the page. Don't know where to start. Have all data just need to do some chi sqaured tests which won't take long.. could use some combined brainpower as help if possible? Any tricks to cut corners?
