Cоnsider the fоllоwing three biаses: observer biаs, sociаl desirability bias, and voluntary response bias. For each bias: first briefly define that bias. Second, describe a needfinding scenario where that bias might occur and how it might affect the results of the needfinding exercise. Third, describe how the researcher might revise the situation to mitigate that bias. Do these three things for each of the three biases.
