Answer 1

im pretty sure that's right... @Alexistheamazing

Answer 2

yea that is right @Hannah_Waller @Alexistheamazing

Answer 3

no I don't think that IS correct

Answer 4

the centre of the set has the same number of samples above it as below

count the crosses

There is a value which meets the above definition - and it is not 115

Answer 5

There are 3 'normal' ways of defining the 'centre' of th edata:

Mean (add all values and divide by number of samples)
Median (the middle value when all samples are listed sequentially)
Mode: (The value that occurs most frequently in the list)

115 is none of those

Answer 6

it is 110

Answer 7

you see the number that has most x and 110 is that number

Answer 8

@bilaleid

Both 110 and 120 have the same number of points - so your answer is not entirely correct.
