what is the type of sample in which each member of the sample set or group has an equal chance of being chosen
A sample that accurately reflects the characteristics of the population as a whole
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.
Convenience sample
Will a sample descriptive statistics accurately estimate the underlying population's parameters?

That the key characteristics of the population are reflected in the sample.
