Parametric statistics is a branch of statistics which assumes that sample data comes from a population that can be adequately modeled by a probability distribution that has a fixed set of parameters. Conversely a non-parametric model does not assume an explicit (finite-parametric) mathematical form for the distribution when modeling the data. However, it may make some assumptions about that distribution, such as continuity or symmetry. WebMar 9, 2024 · Researchers use the parameter to describe the data distribution of ratios and intervals. The mean is obtained by summing and dividing the values by the number of scores. For example, in five households that comprise 5, 2, 1, 3, and 2 children, the mean can be calculated as follows: = (5+2+1+3+2)/5. = 13/5.
