range=greater value- lowest value
=50-30=20
A.M= 34+37+30+38+50+34+34+38+36+45+31/11
=407/11
=37
to find median, we have to arrange data in ascending or descending order
If there is an odd number of results, the median is the middle number.
If there is an even number of results, the median will be the mean of the two central numbers.
30,31,34,34,35,36,37,38,38,45,50
since, there is odd no of results
so median will be middle no i.e, 36.
The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode of the list.
so mode will be 34 or 38
