Which measures of central tendency get affected if the extreme observations on both the ends of a data arranged in descending order are removed?
Mean and mode
The correct answer is (a) Mean and mode
Solution
The average or Arithmetic Mean or mean of a given data is defined as Sum of all observations by the Number of observations.
Mean is defined as the average of the given numbers. Mean is the sum of all the given data values divided by the total number of data values given in the set.
It is given by:
Mean = Sum of Observations/Total number of observations
Mode is the observation that occurs most frequently in the data. A mode is defined as the value that has a higher frequency in a given set of values. It is the value that appears the most number of times.
