Effect of different temperatures on the permeability of beetroot cell membrane. Aim- to investigate the effect of different temperatures on the permeability of beetroot cell membrane. Prediction: I think that the higher the temperature the higher the absorbance of the liquid into the beetroot membrane. Table of results Average temp (ºC) Group 1 absorbance (Arbitrary units) Group 2 absorbance (Arbitrary units) Group 3 absorbance (Arbitrary units) Average absorbance (Arbitrary units) 25 0.05 0.26 0.13 0.14 35 0.16 0.34 0.09 0.19 45 0.27 0.21 0.19 0.22 55 0.57 0.63 0.29 0.49 65 0.73 2 0.38 1.03 75 1.37 2 0.49 1.28 85 1.66 2 1.94 1.86 Statistical analysis Spearman rank correlation The reason for the statistical analysis is to find out if group 1, 2 and 3 and average absorbance is a positive or negative correlation or no correlation at all. Group 1 In group 1 each absorbance was increased when the temperature was increased so the rank was not changed therefore the rs was 1. This means it is over the critical value (0.79) therefore there is a positive significant correlation between the two values. Group 2 Site Temp (ºC) Rank R1 Absorbance (Arbitrary units) Rank R2 D (R1-R2) D2 1 25 1 0.26 2 -1 1 2 35 2 0.34 3 -1 1 3 45 3 0.21 1 2 4 4 55 4 0.63 4 0 0 5 65 5 2 6 -1 1 6 75 6 2 6 0 0 7 85 7 2 6 1 1 0 8 From using the formula the...
