Statistics investigates and develops specific methods for evaluating hypotheses in the light of empirical facts. A method is called statistical, and thus the subject of study in statistics, if it relates facts and hypotheses of a particular kind: the empirical facts must be codified and structured into data sets, and the hypotheses must be formulated in terms of probability distributions over.

Scientists are judged on the basis of how many correct hypotheses they propose (in the statistical sense of the word) since your estimate is not the true value.
Neither the words nor the concepts science and nature were part of the conceptual landscape in the ancient near east.

Statistics is a mathematical body of science that pertains to the collection, analysis, interpretation or explanation, and presentation of data, or as a branch of mathematics. Some consider statistics to be a distinct mathematical science rather than a branch of mathematics.
All students of science need to understand and be able to employ statistical analysis. Statistics can be used, intentionally or unintentionally, to reach faulty conclusions. Highly manipulated claims are unfortunately the norm in advertising and drug companies are notorious for misleading information.
Oct 10, 2019 ironically, the idea that data provide a basis for scientific theories fails but scientific knowledge is not a class of evidence-based true beliefs.
You can perform statistical tests on data that have been collected in a statistically valid manner – either through an experiment, or through observations made using probability sampling methods. For a statistical test to be valid, your sample size needs to be large enough to approximate the true distribution of the population being studied.

Tests for statistical significance tell us what the probability is that the a null hypothesis may also state that the relationship proposed in the research hypothesis is not true.

Statistics in research is not just about formulas and calculation. (many wrong conclusions have been conducted from not understanding basic statistical concepts) statistics inference helps us to draw conclusions from samples of a population. When conducting experiments, a critical part is to test hypotheses against each other.
These observations are based on specific events that have already happened and can be verified by others as true or false.
Hypothesis testing is a widespread scientific process used across statistical and social science disciplines. In the study of statistics, a statistically significant result (or one with statistical significance) in a hypothesis test is achieved when the p-value is less than the defined significance level.
