What are statistics calculated from
Samples
Statistics are calculated from data. Data can be of different types such as numerical, categorical, time-series, spatial, and so on. These data are collected through various sources such as surveys, experiments, observations, and various other methods. Once the data is collected, statistical methods are used to organize, summarize, and analyze the data. This analysis creates important measures such as means, standard deviations, correlations, regression coefficients, confidence intervals, and p-values, which help to give insight into the data and its underlying population. These measures are then used to draw conclusions, make predictions, identify patterns and relationships, and test hypotheses. Ultimately, statistics are used to gain knowledge from data and to make informed decisions.
