Answer:
Median ( Q2) = 6
Q1 ( lower quartile) = 4.5
Q3 ( upper quaartile) = 10.5
Step-by-step explanation:
<u>3,4,4,5,5,6, </u>6,6 ,<u>6,7,9,12,14,15</u>
6,6 is the median but we only need I median. So 6 + 6 = 12, 12 divided 2 = 6.
3,4,<u>4,5,</u>5,6, is the Q1 ( lower quartile ) and median of Q1, is 4,5. 4 + 5 = 9. 9 divided 2 = 4.5
6,7,<u>9,12,</u>14,15 is Q3 ( upper quartile) 9,12 is median but we only need one. So 9 + 12 =21. 21 divided 2 = 10.5
