Answer 1

Mode is the data with the most number of appearances. Or the most frequent value.
Say you have the set of data as
1,5,7,8,8,9
In this case, 8 is the mode since it appeared twice

Answer 2

Answer 3

Median is the middle of the given set
Taking the same set:
1,5,7,8,8,9
Notice that there are two middle values-7and8
then take its average. (7+8)/2 = 7.5
Therefore the median is 7.5

Answer 4

For this set of data
1,5,7,8,9
The middle term is 7. Therefore 7 is the median

Answer 5

is the answer to Q2 15?

Answer 6

Mean simply implies that you need to get the average value of the set of data.
Say you have the same set of data as above
1,5,7,8,8,9
Get the sum of it
1+5+7+8+8+9 = 38
Divide it by the number of data being added. In this case there are 6 of them so you'll have
38/6 = 6.33
6.33 is the mean
