Déan trastomhas na réigiún coiscthe a thomhas go dtí an 0.1 mm is gaire. Déan na tomhais mheánacha i leith gach tiúchain a thaifeadadh ar ghrafpháipéar leathlogartamach ag taispeáint logartam na dtiúchan i gcóimheas le trastomhais na réigiún coiscthe.
Measure the diameter of the zones of inhibition to the nearest 0.1 mm. Record the mean measurements for each concentration on semi-logarithmic graph paper showing the logarithm of the concentrations in relation to the diameters of the zones of inhibition.
