Alright... Do you know how to find the mean, median or mode?

anonymous · Answer

yes

anonymous · Answer

Then find the median, mode and mean from the scores and tell me them.

anonymous · Answer

a)mean: ?
   median: 97, 58
   mode: 58

anonymous · Answer

Ok, add each number up and then divide them by how many numbers there are so.

86 + 75 + 97 + 58 + 94 + 58 = ans
ans/6= mean

anonymous · Answer

78?

anonymous · Answer

so:
mean: 78
median: 97, 58
mode:58? :)

anonymous · Answer

Your median is wrong. You're supposed to order the number from short to least, and then tally them out...

anonymous · Answer

ohh ok sry, let me try again
