observations of a data are 16,72,0,55,65,55,10,and 41.chaitanya caluclatedthe mode and median without taking zero into consideration.did chaitnaya do the right thing?
Answers
mode in that number which appears most often in the observation
in the above observation mode is 55 as this has appeared twice in the observation while other observation has appeared only once.
Median is the middle number in a sorted list of numbers. To determine the median value in a sequence of numbers, the numbers must first be arranged in value order from lowest to highest. If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above. If there is an even amount of numbers in the list, the middle pair must be determined, added together and divided by two to find the median value. The median can be used to determine an approximate average, or mean. The median is sometimes used as opposed to the mean when there are outliers in the sequence that might skew the average of the values. The median of a sequence can be less affected by outliers than the mean.
zero is ignored as mentioned in the statement
10,16,41,55,55,65,72
as middle value in the above numbers is 55
hence median is also 55
so both median and mode are 55
