Answer:To betterunderstandthe data you're working withStep-by-step explanation:Note that, thesampleis a subset of your wholepopulation(population here is a general definition, it could be a population of cars for example), which means that if you want to understand your population your best "bet" would be using a sample to try toestimatesome unknown characteristicsof your population. Let's suppose you want to estimate thetrue meanof your population, then you would need a sample, and if this sample is big enough you could approximate the estimative to the true mean.It's hard to say exactly what this survey could mean, but the general idea is to understand your data a little more, see if there is any pattern, if a certain value occurs more than others, to calculate the sample mean, median and standard deviation, and so on...Hope it helped!...
