Statistikafunktsioone

Statistikafunktsioone, also known as statistical functions, are mathematical operations used to analyze and interpret data. These functions are fundamental in statistics and data analysis, providing insights into the characteristics of a dataset. Common statistikafunktsioone include measures of central tendency, such as the mean, median, and mode, which describe the central value of a dataset. Measures of dispersion, like the range, variance, and standard deviation, indicate how spread out the data points are. Additionally, correlation functions, such as the Pearson correlation coefficient, assess the relationship between two variables. Probability distributions, including the normal distribution and binomial distribution, model the likelihood of different outcomes. Hypothesis testing functions, such as t-tests and chi-square tests, evaluate the validity of assumptions about a population based on sample data. These statistikafunktsioone are essential tools for researchers, analysts, and decision-makers, enabling them to draw meaningful conclusions from data and make informed decisions.
