About Confidence Intervals and how are they useful

  • Getting feedback from everyone would be great, but it's just not possible.
    • We can instead get feedback from a sample that we assume represents the entire population.
    • The problem with taking samples is:
      • Our sample mean may be similar to the population mean.
      • However, we might collect a sample and the mean is actually much different from the population mean.
  • By calculating the confidence intervals around any data we collect:
    • The lower limit and upper limit around our sample mean tells us the range of values our true population mean is likely to lie within.
    • Confidence intervals give us richer data.
  • The range of these confidence intervals adjusts based on the sample size of your study. For more information on Sample Size, check out the How many participants do I need? video in the UserZoom Academy.
