It is better to tell your best girl friend that that dress does not flatter her figure; however telling her how much she resembles the 2 hams stuffed in a burlap sack is not the best approach. I think that is where people get confused. Lyingâ¦(or sugar coating) is what people do today instead of telling the truth.
Quartiles divide a rank-ordered data set into four equal parts. The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively. Note the relationship between quartiles and percentiles. Q1 corresponds to P25, Q2 corresponds to P50, Q3 corresponds to P75. Q2 is the median value in the set.
One definition of percentile, often given in texts, is that the P-th percentile (< â¤) of a list of N ordered values (sorted from least to greatest) is the smallest value in the list such that no more than P percent of the data is strictly less than the value and at least P percent of the data is less than or equal to that value.
