hey...i'm kinda confused...to determine dependent &n independent variable...someone can teach me??
one example...let's say in an experiment, we want to know the effect of several solution on size of stomata...we use several solution, and it's said that the concentration needs to be trialled depending on the leaves used(umm...why??)...what's the independent &dependent variable??

the dependent variable is the dry leaf...as its written in the question...and the independent variable is time...as the time taken for the solution to effect the leaf cant be controlled.

independent variable is alwas the x axis in the graph...and dependent variable y axis...so whatever ur independent variable is your dependent variable will change accordingly!!

And chi squred jst knw that what if the chi squared value is above ur probality at 0.05% then difference between observed and expected is significant...n if its less its not significant and more due to chance...... ;)

PLANNINGS GNA B HARD!!!!nov 2008.....nt answers tht can b jst guesd at a time like tht!!!
