read the first word pair. make the next word pair by taking the second word from the
previous word pair and combining it with a word from the word bank. word pairs must
combine to form either a compound word or words that are often used together. the

First Task: Data Comparison

Step1: Order data for Homeroom A

Sort the values: $0,1,2,3,4,5,5,6,7,9,9,10,10,15$

Step2: Calculate mean for Homeroom A

Sum values, divide by count:
$\text{Mean}_A = \frac{0+1+2+3+4+5+5+6+7+9+9+10+10+15}{14} = \frac{86}{14} \approx 6.14$

Step3: Find median for Homeroom A

Average 7th/8th values:
$\text{Median}_A = \frac{5+6}{2} = 5.5$

Step4: Order data for Homeroom B

Sort the values: $0,3,4,5,5,6,6,7,8,9,9,10,12,15$

Step5: Calculate mean for Homeroom B

Sum values, divide by count:
$\text{Mean}_B = \frac{0+3+4+5+5+6+6+7+8+9+9+10+12+15}{14} = \frac{99}{14} \approx 7.07$

Step6: Find median for Homeroom B

Average 7th/8th values:
$\text{Median}_B = \frac{6+7}{2} = 6.5$

Step7: Compare distributions and centers

Both sets range 0-15; Homeroom B has higher center values.

Each pair uses the second word of the previous pair, paired with a word from the bank to form a compound/collocation, ending at "ball, game".

Answer:

Homeroom A has a mean of approximately 6.14 and a median of 5.5. Homeroom B has a mean of approximately 7.07 and a median of 6.5. Both datasets have a minimum of 0 and maximum of 15, but Homeroom B's measures of center are higher, indicating that students in Homeroom B read more books on average over the summer than students in Homeroom A.
