Statistics
Statistics is a science in which special profile mathematical methods are used to systematize and process obtained data. Statistical results allow for both purely practical and scientific conclusions on various problematic topics.
Many branches of science, technology, and the state as a whole receive objective information that is important for the implementation of innovative ideas and reforms. The initial data for using statistical methods are information in the form of large extensive sets that have the necessary characteristics.
The section presents the most in-demand online calculators, allowing you to calculate sample size, determine error when identifying a confidence interval, determine the correlation coefficient, variance, and more.
Statistical Online Calculators
| Confidence Interval Calculation calculate error | Sample calculation sample size |
| Geometric mean extracting the root from the product | Correlation-Regression Analysis correlation coefficient |
| Arithmetic mean Variance, Variation, Standard Deviation, Mean Linear Deviation | Harmonic Mean or Mean Harmonic |
| Root Mean Square Deviation it is also the standard deviation, standard deviation | Weighted arithmetic mean weighted arithmetic mean of a set of numbers |
