WHAT ARE THE KEY ADVANTAGES OF USING R FOR STATISTICAL ANALYSIS?
Statistics in R encompass a broad spectrum of functionalities and packages designed to perform various statistical analyses, data exploration, hypothesis testing and modeling tasks. R is extensively used in data analysis, academia, industry, scientific research and statistical computing due to its rich set of statistical tools and packages. Some key statistical functionalities in R include:
-
Descriptive Statistics
R offers functions to compute basic descriptive statistics such as mean, median, standard deviation, variance, range, quartiles, percentiles, and summary statistics for data exploration (summaryfunction). -
Hypothesis testing
R provides functions for conducting various statistical tests, including t-tests (t.test), chi-square tests (chisq.test), ANOVA (aov), F-tests (var.test), and non-parametric tests (such aswilcox.testorkruskal.test). -
Probability distributions
R includes a wide array of functions to work with probability distributions (e.g., normal, uniform, binomial, Poisson) for generating random numbers, calculating probabilities, quantiles, and density functions.
