Correct Answer - Option 2 : Distribution free statistics

Distribution free statistics:

  • Statistical methods that do not rely on the assumption of a known population probability distribution function for their validity are called Distribution‐free Statistical Methods (also called nonparametric statistical methods).
  • Nonparametric statistics does not assume that data is drawn from a normal distribution. Instead, the shape of the distribution is estimated under this form of statistical measurement. So, If the sample drawn does not specify any condition about the parameter of the population, it is called Distribution free statistics.
  • The term nonparametric is not meant to imply that such models completely lack parameters, but rather that the number and nature of the parameters are flexible and not fixed in advance. A histogram is an example of a nonparametric estimate of a probability distribution.​

Parametric statistics:

  • 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. So, this option is eliminated as this doesn’t follow the question been asked.

Inferential statistics:

  • Inferential statistics takes data from a sample and makes inferences about the larger population from which the sample was drawn. Because the goal of inferential statistics is to draw conclusions from a sample and generalize them to a population. Eliminating this option too as this doesn’t follow the question been asked.

Selected Statistics: In statistics, there is no term known with this name.

So, If the sample drawn does not specify any condition about the parameter of the population, it is called Distribution free statistics, that’s why option 2 follows
