Interviewer instructions

Record the average amount of a purchase. For example: if the response for question
6 is 5 KGs of rice each time; the interviewer will record this to the quantity column, record 2 to
the unit column (kg code 2). If the respondent says 5 mugs or measures ... then the interviewer
has to convert mug or measure ... into the equivalent measures listed in the questionnaire.
For example: 1 measure = 0.8 kg
5 measures = 4.0 kg (5 x 0.8)...
In reality, the times of purchase among different months and the amount each time vary.
Some households can’t even remember the number of times purchased and the amount each time,
if this happens, the interviewer has to prompt on the basis of the information obtained. In
principle, The interviewer should rely on the theory of average numbers to estimate the frequency
of times and the amount purchased.
