Construct a neat and compact table, including title and footnotes if required, to summarise the following information taken from rough notes:
‘Acid A was titrated by four analysts and the following end points were obtained: 20.2mL, 20mL, 21mL and 20.8mL, the conductivities were also measured as 13, 13.6 13.8 and 14.2 micro-siemens respectively. The base used for the titration was 0.1 M sodium hydroxide. Acid B was titrated by four analysts and the following end points were obtained 210.2mL, 200mL, 211mL and 206.8mL, the conductivities were also measured as 12, 12.6 13.0 and 12.2 micro-siemens respectively. The base used for the titration was 0.1 M potassium hydroxide.
