Applications of Confidence Intervals
The calculation of confidence intervals is probably one of the most commonly used
statistical tools by researchers and business managers.
In contrast to point estimates, confidence intervals enable the individual to have an idea
of not only the central tendency of a series of data but also of how much variation he may expect
within the data around such fundamental tendency measure. As such, it is possible to construct a
confidence interval for each of the statistical parameters used to describe the population of data.
For example, it is possible to find in the literature confidence intervals describing the minimum
and maximum values within which the researcher expects to see the population's mean, the
population's standard deviation, or the population's proportion coefficient, among others. The
exact method used in the estimation of such minimum and maximum levels that delimit such
confidence interval will depend on the exact type of property from the population described
through the use of the confidence interval.
The main reason for using a confidence interval is that their use enables the researcher to
define the minimum and maximum limits where there is a given likelihood of finding the
population’s characteristic under study (Pirikabu et al., 2016). Through these limits, the
researcher can then compare whether ...
