The number of respondents you need depends on your survey goals and how confident you want to be in your results.The more confident you want to be, the less of a margin of error you should accept.The following observations need to be taken into account when determining sample size: a) The magnitude of sampling error can be diminished by increasing the sample size.b) There are greater sample size requirements in survey-based studies than in experimental studies.Using a 95% confidence level and ±5% margin of error, if we repeated this survey 100 times under the same conditions, 95 out of 100 times, the response would be somewhere between 50% and 60%.A confidence level tells you how reliable a measure is.When calculating your sample size, you'll use the z-score for your confidence level.The z-score is the number of standard deviations a given proportion is away from the mean.In general, the larger your sample size, the lower the margin of error.The closer your sample is in size to your population, the more representative your results are likely to be.
