    no ur wrong.... null hypothesis= no significant difference between the means... so significnt diff= reject the null hypothesis

    see..o.o5 is the decider value...if the probability is lower than dis, den we can say dat it is very unlikely dat the null hypothesis is correct..dat is..der IS a significant difference between the means! hope dat helps!

    you can either consider the critical value at 0.05 probability and comment on the null hypothesis...orelz u can consider the critical value closest to the calculated value...and then comment... dat depends on u.. :)

    okay since u've not taken phy...ummm do u noe how to draw the error bars in the graph..?
  12. X

    Biology paper 5 doubts

    no as far as i hav read it is always +/-(2*std error) and not just +/-(std error) and yeah...it depends on the data given to u...no generalized concept for it as u asked!

    u cant actually qualify it... its lyk..ven u r given 2 different data sets...u got to compare der std deviations..the one wid a greater value of std deviation out of the 2..wil b less reliable..

    oh..ohk..i hav posted wt is std error..pls hav a luk.. and yeah for dat questn in 53/o/n/10 we only got to +/- (2*std error) for the error bars
  15. X

    Biology paper 5 doubts

    dat question is not related to the data..dey hav asked a general question..so the std deviation shows the spread of data from the mean! :)

    Biology paper 5 doubts

    ohh..ohk i'l tel u in short.. c error bars are basically sumthing lyk v do in phy..have u taken phy? bt the only difference is that instead of doing +/- uncertainty in phy... for bio we +/- (2*standard error) ...and standard error is given by S/(root of n), where S=standard deviation and n=no...

    Hey its not poss to explain d entire thing lyk dat..pls hav a luk at the ppr which i mentioned..53/o/n/10 u'l cm to noe wt were v tokng abt.. N i'l sugest u to go thru sum revision guide if u hav 1..for better undrstnding.. :-):-)

    Biology paper 5 doubts

    Hey thnx bt if u see 53/o/n/10 the ms says v got to add and subtract 1 and 2 for the error bars...whereas 1 and 2 are the std errors.. From wt i had studied..v hav to multiply by 2 bt den d ms says sumthng diffrnt..pls check it out n tel me..
