Convenience samples can provide rich qualitative information. It requires significantly less time to question 40 people as they leave a grocery store than a plan, design, and collect a random, representative sample of a population.A type of non-probability sampling method where the sample is taken from a group of people easy to contact or to reach. That involves the sample being drawn from that part of the population that is close to hand. The best way of reducing bias in convenience sampling is to use it along with probability sampling. Since it is usually biased, probability sampling gets the measurement parameter with it to keep this bias under check. Even though convenience sampling can be easy to obtain, its disadvantages usually outweigh the advantages. This sampling technique may be more appropriate for one type of study (Davies HT, Crombie IK).  MATH 225N Week 7 Lab  In Statistics, point estimation involves the use of sample data to calculate a single value (Known as a point estimate since it identifies a point in some parameter space) which is to serve as a “best guess” or best estimate” of an unknown population parameter for example, the population mean from random samples .my point estimate of this data i
