Descriptive Statistics is a branch of statistics used to summarize, organize, and describe the main features of a dataset. It helps in understanding data using numerical measures like mean, median, mode, variance, and standard deviation.
1. Mean

The goal of statistical testing is to minimize both errors simultaneously.
Parametric Tests: Assume data is normally distributed and uses interval/ratio scales (e.g., t-test, ANOVA).

Tax Deducted at Source (TDS)
With TDS, the payer deducts a percentage of tax before paying the recipient and deposits this amount with the government on the recipient's behalf.
