The perfect population and sample size for your survey
In order to have your survey be accurate and really represent the population that you’re trying to learn more about, you need to have the correct population and sample size.
Make sure that you have a large number in your survey so you can learn enough about the target market, without going too big – if you interview too many people, this can lead to obsolete answers from people who do not really use your business. Instead, you need to use a large number of people that are indicative of your target to get the correct sample size, the margin of error, and the confidence level for your survey.
Make sure that you try and keep the confidence level above 95% if possible – confidence levels between 90 and 99% are the most effective when it comes to conducting a reliable survey that tells you information about your ideal clientele. By keeping your confidence level around 95% and keeping your margin of error below 5%, you can ensure that you are using the correct population and sample size.
By keeping your population and sample size the correct number, you can avoid having a very low confidence level. For example, if you only ask 10 people about a question pertaining to your business and you find that 4 out of the 10 participants are outliers, then this can drastically change the result – in this case, you may only have a 60% confidence level. Avoid very low levels of confidence and have an extremely high margin of error by choosing the correct population and sample size.
Make sure that you survey a lot of people – by keeping the number of people as high as possible for your survey, you can make sure that you reduce the margin of error and keep the confidence level accurate. Surveying enough people to keep your confidence level above 90% is the key to having a successful survey.
Anything below this number is not reliable and is inaccurate – any sample size that is too small will not help you learn any valuable information regarding your target market. The more people that you interview and the more surveys you distribute, the lower the margin of error will be.
Conclusion
As you can see, you will need to survey a lot of people to keep the confidence level high and the margin of error as low as you can! To keep the confidence level above 90% and the margin of error at or below 5%, you need to choose the correct population and sample size for your survey.
