this blog was created just to inform everybody of what happened in my life and what you people should know in life.... i will share everything with you so that life would be better and cool...
I only demonstrate for snail 1… so u guys should try for snail 2…

This is the table that u need to draw for the purpose of statistical calculation.
1. rank the stimulation with the highest number being number one. (column 3)
2. rank time with the highest time being number one. (column 5)
3. If 2 data in the column appear to be the same, (for eg, for 9th and 10th stimulation, time both equal to zero,) find the mean value… so… 9 + 10 / 2 = 9.5…. so 9.5 is rank for both….
4. Then find the difference between the rank. (Column 6)
5. Then squared the rank. (last column)
6. Then calculate the ΣD²
7. then use this formula
rs = 1- 6 ΣD²/n(n²-1)
Where n= number pair of data, which is in our case 10.
8. Compare the value u get with critical value… ok… REMEMBER TO CALCULATE FOR SNAIL 2 TOO…
