What is the difference between a percentile and a quartile?
A quartile divides a grouping into four. The first quartile will have the first 25% of the group, the second quartile will have the second 25% of the group, the third quartile will have the third 25% of the group and the last quartile will have the last 25% of the group. For example if a classroom had 20 students who had all taken a test, you could line them up, the top 5 marks would be in the first quartile, the next five would be in the second quartile, the next 5 would be in the third quartile, and the 5 students with the lowest marks would be in the last quartile. Similarly, a percentile divides a grouping, except the group is divided into 100. Each 1% represent 1 percentile.

What is quartile Name different quartiles?
A quartile is a statistical term that divides a dataset into four equal parts, each representing a quarter of the data. The three main quartiles are the first quartile (Q1), which marks the 25th percentile, the second quartile (Q2) or median, which represents the 50th percentile, and the third quartile (Q3), which corresponds to the 75th percentile. These quartiles help to summarize and analyze the distribution of data points.
