The coach times everyone on the team , including himself , running the 100-meter race.Which measure will be the most greatly affected by the inclusion of the coach’s time
Answer to Problem 4STP
F
Explanation of Solution
Calculation:
Mean: Since it is the average of all the entries , coach being best out of all the team , will have time that is lesser than that of others in the team and overall , the outcome after adding his time will be that , each player’s time will be displayed much lesser than their actual time.
So, the group as a whole will be displayed much faster than it actually is.
Median is the central entry , so it will not change much.
Mode is least affected as it is the most occuring entry in the range.
So, the correct option is F.
