If the sample is not representative of the population, then the characteristics
of the sample are not the characteristics of the population.
Example:
If I want to estimate the percentage of the population that are men, and my
sample is the school's football team, my estimate would be that 100% of the
population is comprised of men. What went wrong with my survey ? Simple.
The football team is not a representative sample of the population, at least
not as regards gender.

The most important step to ensure accuracy in a sample is?
The most important step to ensure accuracy in a sample is random selection. By randomly choosing samples from the population, you minimize bias and increase the likelihood that your sample is representative of the entire population. This helps to draw reliable conclusions and make valid inferences based on the sample data.
What is the importance of a representative sample?
Well, if your sample does not represent the larger sample, you'll certainly not get a valid result ... For example, if you're studying pregnancy and your sample includes men - The whole idea of "representative' sample is fuzzy and often gives interesting errors.
