Answer:
• Median for Amo
• Mean for Max
Step-by-step explanation:
Amo's mean score:
= (97 + 92 + 89 + 55 + 90)/ 5
= 84.60
= 85
Max's mean score:
= (68 + 97 + 65 + 92 + 65) / 5
= 77
Amo's median:
First arrange the numbers in ascending order:
55, 89, 90, 92, 97
Median is middle which is 90.
Max's median:
65, 65, 68, 92, 97
Median is 68
Mr Javier should use Median for Amo and Mean for Max.
