Silvia works at the same center that Sarah directs. She has always loved math and statistics. After the conversation at the meetings about students' socio-emotional development, she decides to learn more about her own class. The following scores were those who were in her room, 78, 37, 42, 30, 88, 22, 86, 27, and 15. Jared was not a student in her room, but she is concerned about Isabel. Isabel's score (already shown) was 37. a. What percentile is Isabel in? Based on this information, what should she conclude? b. Given the wide variation of scores, Silvia thinks it is also important to determine where certain percentiles are in her data. This would better allow her to triage students into three different groups. What scores represents the 33rd and 67th percentiles? c. Several weeks later, Silvia learns that she will have a volunteer who will be working with her students to do a behavioral intervention. However, the volunteer (while very experienced) has a limited amount of time, so he can only help a small percentage of her students. She figures that anyone in the 25th percentile and below should be helped first. What score represents the 25th percentile? How many children (or scores) fall at or below the 25th percentile?
