Inferential statistics allows you to create predictions ("inferences") from data (for example, a chart or graph). Descriptive statistics describes data (for example, a chart or graph). Inferential statistics are used to generate generalisations about a population using data from samples.

Hypothesis testing, confidence intervals, and regression analysis are the most frequent inferential statistics approaches. Surprisingly, these inferential methods can generate summary values that are identical to descriptive statistics like the mean and standard deviation.

a variable or several variables to be looked into; • Data conclusions based on the patterns presented in tables, graphs, or numerical summary tools. The inference about the population based on the sample's information; A measure of the inference's trustworthiness.

When you assume that the null hypothesis is true, P values are the chances of seeing a sample statistic that is at least as extreme as your sample statistic. Let's return to our fictitious drug study. Assume a P value of 0.03 is generated by the hypothesis test.

Inferential statistics aid in the development of hypotheses about a condition or event. It differs from descriptive statistics in that it allows you to draw conclusions based on extrapolations, whereas descriptive statistics simply summarise the data that has been measured.
