and the number of respondents you need to interview ateach
site, you can start identifying places in those settlements,
so called “starting points”, from where the interviewers
will start a random walk. The number of required
starting points is calculated by dividing the number of
interviewers by two, i.e., two interviewers per point. These
paired interviewers should walk in opposite directions.
Flip a coin to decide who goes where.
Before beginning a walk, each interviewer should ask another
interviewer to select a card from a blind deck of 10
numbered cards. The number selected will serve as the
criterion for choosing households (secondary sampling
units). In other words, if the card with the number 7 is
selected, the interviewer will visit every 7th household until
he/she completes his/her quota of interviews. If it is not
clear which house is 7th (there might be two houses facing
one another), then the interviewer will flip a coin, with
heads indicating the house on the right and tails indicating
the house on the left. (It does not have to be in this
order, as long as you are consistent.)
