1 Important Research Terms A confidence interval is a statistical range in which an estimate of the true value of a measured item will fall within to give the described certainty. Thus, in using or stating the confidence interval, the researcher implies the confidence they have that the statistic is as indicated. Therefore, an observer or reviewer can determine the precision of the reported findings. Another critical term in research is 'standard deviation. Scholars will cite it in many of their findings and will use it as part of descriptive statistics. It implies a measure's spread or dispersion based on the identified data points. For instance, the average age of boys can be said to be 14 for attending swimming classes. Then, a standard deviation figure is added to show that while 14 is the average, there can be a few points over/under, as noted by the standard deviation. Understanding the standard deviation is crucial for assessing the variability of responses or behaviors.
