Answer:
Emma ⇒ IQR = 3.5
Sally ⇒ IQR = 3
Olivia ⇒ IQR = 2.5
Emma - Sally - Olivia
Step-by-step explanation:
Emma's Scores:
<u>6 , 7 , 8 , 8 , </u><u>9 , 9</u><u> , 9 , 10 , 10 , </u><u>11</u> , <u>11</u><u> , 11 , 11 , 11 , </u><u>12 , 13</u><u> , 13 , 13 , 13 , 14</u>
LQ = (9 + 9) ÷ 2 = 9
UQ = (12 + 13) ÷ 2 = 12.5
IQR = 12.5 - 9 = 3.5
Sally's Scores:
<u>6 , 6 , 6 , 7 , </u><u>7 , 8</u><u> , 8 , 8 , 9 , </u><u>9</u> , <u>10</u><u> , 10 , 10 , 10 , 10</u><u> , 10 , 11</u><u> , 11 , 12 , 12 , 14</u>
LQ = (7 + 8) ÷ 2 = 7.5
UQ = (10 + 11) ÷ 2 = 10.5
IQR = 10.5 - 7.5 = 3
Olivia's Scores:
<u>6 , 6 , 7 , 7 , </u><u>7 , 8</u><u> , 8 , 8 , 8 , </u><u>9</u> , <u>9</u><u> , 9 , 9 , 9 , </u><u>10 , 10</u><u> , 12 , 12 , 13 , 14</u>
LQ = (7 + 8) ÷ 2 = 7.5
UQ = (10 + 10) ÷ 2 = 10
IQR = 10 - 7.5 = 2.5
Emma - Sally - Olivia
