Let's discuss populations, parameters, and their relationship to point and interval estimations. Starting with the August 2018 release of Power BI Desktop, you can create what-if variables for your reports, interact with the variable as a slicer, and visualize and quantify different key values in your reports.. Mathematics. A parameter is a characteristic of a population. For each study, identify both the parameter and the statistic in the study. A parameter is a population quantity used to describe some characteristic of a population. In simple words, a parameter is any numerical quantity that characterizes a given population or some aspect of it. parameters: MLE, Bayesian estimation.
