Five types of electrodes were applied to the arms of 16 subjects and the resistance measured. The experiment was designed to see whether all five electrode types performed similarly.
After obtaining the results, the experimenters decided that the reason for the two large readings on subject 15 was the excessive amount of hair of those parts of the subject's arm. They concluded that this subject's data should be deleted.
|E1||Resistance measured by electrode type 1|
|E2||Resistance measured by electrode type 2|
|E3||Resistance measured by electrode type 3|
|E4||Resistance measured by electrode type 4|
|E5||Resistance measured by electrode type 5|
