CONDITION 2 Dry and humid conditions will have no significant effect on the behaviour of the woodlice. CONDITION 3 Dry/Light and Damp/Dark conditions will have no significant effect on the behaviour of the woodlice. DEGREES OF FREEDOM Degrees of Freedom = No of Categories - 1 2 Categories in each of the three experiments Therefore 2 - 1 = 1 The critical value of ?2 = 3.84 ?2CRIT = 3.84 At the 5% probability level the calculated values ?2 for each of the experiments are: - Dark/Light - 21.16 Dry/Damp - 49 Light & Dark/Dry & Damp - 33.64 All these values ?2 are greater than the critical value, we therefore reject the null hypothesis and say there is no significant difference between the...
