### Lab 7 Evaluation of muscle relaxation action of Diazepam using Rotarod (Con't...d)

#### q value in one way ANOVA:

Dunnett test q value = $(\bar{x_1}-\bar{x_2})/SE_{diff}$. If the value of q is greater than 2.440 then the P value is less than 0.05. Again if $q>4.63$, $0.01>p>0.001$

Tukey test: q value = $(\bar{x_1}-\bar{x_2})/ \sqrt{(SE^2_1 +SE^2_2)}$

[x = value of each sample; n = no of sample in a group; P = Percentage; $SE_{diff} = \sqrt{(SE^2_1 +SE^2_2)}$]

Mode of presentation: Bar or column chart: A separate horizontal or vertical bar is drawn for each group, its length being proportional to mean of that group. The bars are separated by small gaps to indicate that the data are discrete. Bar is given in the top of the column (mentioning $\sigma/SE$).
