Someone to clarify to what each of this terms corresponds exactly ? and what if one refers to the 2nd decile or the 3rd quantile ? Percentile: you divide your population or sample by 100%. So the 12 percentile is 12% and the 4th percentile is 4% ? Quintile ? Decile ? Quantile ? Quartile ?

never mind, got it. just have to divide by 100 depending on what you have. Just know that quintile is 5, decile 10, quartile 4 percentile 100 and the mediane for the most common one

Quintile - divide population by 5 Decile - divide population by 10 Quantile - just refers to a point that you have used to divide up a population Quartile - divide population by 4

The 2-quantile is called the median The 3-quantiles are called tertiles or terciles → T The 4-quantiles are called quartiles → Q The 5-quantiles are called quintiles → QU The 6-quantiles are called sextiles → S The 10-quantiles are called deciles → D The 12-quantiles are called duo-deciles → Dd The 20-quantiles are called vigintiles → V The 100-quantiles are called percentiles → P The 1000-quantiles are called permilles → Pr P

Miss Yiota, median is the middle no. mode is the most common, i hope ur sentence above was a typo.
