A It is suspected that an acid base titration method has a significant indicator error and thus tends to give results with a positive systematic error i e a positive bias To test this an exactly 0 1 M solution of HCI is used to titrate 20 00 mL of an exactly 0 1 M solution of NaOH and the following results were obtained 20 06 20 18 19 87 20 51 20 34 20 41 Test for positive bias in these results at 95 confidence leve
