Understanding how much our results may differ if we did the study again, or how uncertain our findings are, allows us to take this uncertainty into account when drawing conclusions. Inferential techniques attempt to describe the corresponding characteristics of the population from which the sample data were drawn. Inferential statistics use a random sample of data taken from a population to describe and make inferences about the population. Statistical inference involves the process and practice of making judgements about the parameters of a population from a sample that has been taken.

Numerical measures are used to tell about features of a set of data. Statistical significance is a term used by researchers to state that it is unlikely their observations could have occurred under the null hypothesis of a statistical test.Significance is usually denoted by a p-value, or probability value.. Statistical significance is arbitrary - it depends on the threshold, or alpha value, chosen by the researcher. Analysis of variance, or ANOVA, is a technique from statistical interference that allows us to deal with several . Nobody believes that an LSTM model .
