    Can't think of any skill that I mentioned in the forum that came in handy!!!!!!!!!!

    the thing is the book quotes it as +-2Sm and this would result the range being 4SM

    Biology P5

    Use the 2Sm. It covers the 95% range and hence is more appropriate than 1 Sm which I think only covers 67% range

    Light independent process involves enzymes. At low temperatures the enzyme activity is low but it is not zero. So, we start the graph with a y-intercept. As the temperature increases, we begin to approach the optimum temperature of the enzymes. So, the rate increases. However, as we overshoot...

    Yeps. Questions have been asked both pre-2007 and post 2007 regarding immobilisation and making alignate beads in the lab.

    The method for averaging works as well because we expect all the three values to be the same (null hypothesis again). But the data aren't same. So, the only reason could be experimental error. The three data are so different that we can not exclude any one of them as being anamolous. So left...

    So, we expect no change at all (as stated by the null hypothesis), so the results should be the same, regardless of how many years the grassland is left grazed or ungrazed (which is not even a word in the dictionary, CIE really needs to check what they write). So, whatever results we get, we...

    If you are asked to reason why a given data is anomalous : 1. First mention that it doesn't fit the general trend and give a reason supporting that 2. Mention what kind of experimental errors could have resulted in the anomalous result

    This is not very important but we can never be sure if CIE picks on this : Be careful about the use of AGAR and AGAROSE: Use agar in the context of microbiology Use agarose in the context of gel electrophoresis

    buddy you need to be more specific about what confuses you!

    Points required for planning: 1. Varying the independent variable: -Suggest how to vary the independent variable -How the value of the independent of variable will be measured -Which values of the independent variable will be used (MENTION AT LEAST FIVE VALUES) 2. Measuring the dependent...

    Now comes the monster, the T-TEST: ALWAYS KEEP IN MIND THAT T-TEST ONLY WORKS FOR CONTINUOUS DATA!!!!!!!!!!!(unlike chi-squared test) First we need to understand the standard error: It is the standard deviation of the sampling distribution of the sample mean. This distribution is always a...

    Now, let us consider how we can consider how we can prove if the null hypothesis is right or wrong. To do that, we have to check the SIGNIFICANCE OF OUR RESULTS. Please realize that I am explaining what I write to myself as much as I am explaining it to you The all important term...

    BIO-STATS: This could have been much better explained by someone who has taken STATS II, but I unfortunately haven't done that. So , you will have to unfortunately bear with and CORRECT my misunderstandings. First of all, we need to realize that irrespective of how scary the terms such as...

    To determine the extent to which hypothesis is supported by results, consider: 1. The general trend shown by the results 2. Anomalous results 3. Sample size 4. Repeats 5. Range of independent variable for which sample is taken 6. Whether or not tests have been carried out to check the...
