Table 3. Paper-tablet discrepancies and device attributable coding errors for the field research assistant teams.

Discrepancies & Type of error	Team-A (n = 24)		Team-B (n = 47)		Team-C (n = 24)		p-value
	Mean	%	Mean	%	Mean	%
Discrepancies	10.50	4.49	9.26	3.96	15.46	6.61	<0.0001
Paper errors	4.29	1.84	4.09	1.75	6.25	2.67	0.009
Tablet errors	4.96	2.21	3.66	1.56	6.29	2.69	0.0004
Both paper and tablet errors	0.58	0.25	0.26	2.69	0.62	0.26	0.07
Unattributable errors	0.67	0.29	1.25	0.26	2.30	0.98	NA

n: number of interviews.

%: Percentage of errors with reference to 234 comparison fields. p-value: Simple mixed binomial regression model with factor urban and rural.

NA: Not applicable.

The difference between the means of paper errors and tablet errors for each field-research team is statistically insignificant. Paired t-test p-values for team A, B and C are 0.50, 0.45 and 0.97 respectively.
