Quartiles Percentiles 44Af44

1. The problem asks to identify the percentiles corresponding to the first quartile (Q1), the median, and the third quartile (Q3). 2. Important definitions: - Quartiles divide data into four equal parts. - Percentiles divide data into 100 equal parts. 3. The first quartile (Q1) is the value below which 25% of the data fall, so it corresponds to the 25th percentile. 4. The median is the middle value, dividing data into two equal halves, so it corresponds to the 50th percentile. 5. The third quartile (Q3) is the value below which 75% of the data fall, so it corresponds to the 75th percentile. Final answers: - The first quartile (Q1) corresponds to the $25^{th}$ percentile. - The median corresponds to the $50^{th}$ percentile. - The third quartile (Q3) corresponds to the $75^{th}$ percentile.
