1) Ensure that the data collectors are able to recognize whether the marketing practices mentioned by the respondent were those that the project promoted or not. During the training of data collectors, use many examples, scenarios and role-plays. Strengthen further the data collectors’ skills during the subsequent piloting and supervision.
2) If you want to measure the extent to which the respondents’ households have increased their income, you can ask them the following question:
Q4: How big was the increase in your household’s monthly income that you achieved as a result of using these marketing practices?
When asking about this question, ensure that the enumerators do not ask about households’ actual income – they should just focus on by how much money has the income (on average, per month) increased. Make sure that you pre-test asking this question. If you sense that people are reluctant to give an accurate answer, consider asking whether the monthly income has increased, for example, by less than 20 USD, 20 to 50 USD, by between 50 and 100 USD, by 100 USD and more, etc. – people might be more willing to answer if they do not have to state the exact amount.
3) It is recommended that you also measure which of the marketing practices used the respondents perceive as most effective. You can assess their effectiveness by asking:
Q4: In your experience, what was the marketing practice that helped you the most to increase your household income? Please select only one, most effective practice.
A4: include a list of marketing practices promoted by the project + as the first option include “other practice not promoted by the project – specify: ……………”
Q5: Could you please tell me what the second most effective marketing practice was? Again, please mention only one.
A5: include a list of marketing practices promoted by the project + as the first option include “other practice not promoted by the project – specify: ……………”
