Data arranged in ascending order are : 42, 47, 49,50, 52,53,55
As mean can be find by dividing sum of all the observations divided by total number of observations.
Median gives the middle value of the Data. If number of observation is odd, median ==
= 4 th observation= 50
If n is even, then Median = Mean of and[
+1 ] th term.
Mode is that data which appears maximum number of times.
Range = Maximum value in a data - Minimum value in the Data
Correct option is Median.
