1. Decile for Ungrouped Data

2. Find 𝑄1, 𝑄2, 𝑄3 of the given data: 12, 10, 8, 14, 15, 17, 19,10, 7, 10, 9 2. 66, 70, 54, 50, 80, 85, 50, 90, 30, 20

3. A math teacher conducted a survey of 19 randomly selected students in his class and obtain the following data on their everyday expenses. 40, 30, 30 25, 20, 45, 60, 35, 40, 20, 50, 25, 35, 40, 35, 70, 60, 35, 30 What is the least expenses incurred every day? largest expenses?  If the data arrange in ascending order and divide it into 10 equal parts, what are the data belongs to the to the 1st , 2nd , 3rd … to tenth part?

4. Can you determine the position of each partitioned number? The partition numbers are 4, 6, 8, 10, 12, 14, 16, 18, 20 These partitions represent for the decile. Decile 1 (𝐷 1 ) = 4 Decile 2 (𝐷 2 ) = 6

5. Suppose the given scores are the following: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 How many scores are there? Can you determine the 𝐷 1 , 𝐷 2 , 𝐷 3… ,𝐷 9… ? How?

6. Based from the given data, determine 𝐷1,𝐷3,𝑎𝑛𝑑 𝐷9 . 1. 17, 18, 19, 21, 27, 27, 30, 32, 36 2. 41, 37, 30, 25, 21, 18, 16, 16, 15, 14

7. Based from the given data, determine 𝐷 1 ,𝐷 3 ,𝑎𝑛𝑑 𝐷 9 . 1. 24, 19, 25, 34, 26, 45, 36, 38, 29 2. 10, 8, 11, 15, 18, 28, 24, 30, 29, 32
