I am confident enough for planning.
Still finding ways for analysis. Like Describe the graph/results etc.
For stats just UNDERSTAND and thats it. I memorize some of the definitions and questions of past papers.
For stats they always repeat.
ANYONE knows how to analyze data?? Like which one is anomaly, why, desribe blah blah blahhh

A solution of substance Y, thought to be a growth hormone, was made by dissolving a known
mass of Y in 10 cm3 of distilled water. This solution was added to samples from a culture of
animal cells containing 3000 cells per mm3.

Guys, Check out the EXAMINER REPORT
MUCH MORE HELPFUL THAN THE MARKING SCHEME
YOU GET TO KNOW WHAT WORDS THE EXAMINER WANTS YOU TO USE
THEY EMPHASIZED SIGNIFICANCE, RELIABILITY, ACCURACY AND PRECISION
THEY ALSO TELL US THE COMMON MISTAKES SO WE CAN AVOID THEM
Those are my inputs for 2mrw's papers
Good luck guys :D :D :D

thanks but the er has only 52 not 51 :'(

Read the questions properly bro
3000 per mm^3
The table refers to THOUSANDS
so 3000= 3 thousands= 3
:)

guys.. i am confuse about the error bar.. say the error, Sm is 0.2, so do i plot 0.2 above the graph and 0.2 below the graph or is it 0.1 above and 0.1 below?

If Sm is 0.2, then you plot 0.4 on top and 0.4 below
