HELP ME WITH THIS PLSSSS

Answer 1

Answer:

Jack should use the Median

Step-by-step explanation:

The median is the numbers in the middle of the list of numbers.

81, 87, 93, 89, 61, 81

93, and 89 are the highest numbers, and they're in the middle, so therefore the median is the best option.

if we use the mean we get 82 for the test scores.

and the mode would only be 81.

Answer 2

Answer:

It is median.

Step-by-step explanation:

a) The mean is the average of all the numbers: (81+87+93+89+61+81)/6= 82

b) The median is the middle value when the numbers are arranged in ascending order.

61,81,81,87,89,93

since it's an even number, we take the two middle numbers, in our case 81+87=168/2=84

c) The mode is the most frequent data, which in our case is 81

d) It would be the median because it has the highest grade he could get from the other options.
