a.
To evaluate a real-world example where mean represents the best data.
a.
Answer to Problem 10PPS
Mean is used to calculate the final grade of a student in schools and colleges.
Explanation of Solution
Given:
Mean.
Formula used: Advantages and disadvantages of mean.
Mean calculates the average of the given data. The final grade a student gets is the mean of all the marks he/she gets in the whole semester. This mean represents the total number of points you scored in the class divided by the number of possible points.
Conclusion:
Mean is used to calculate the final grade of a student in schools and colleges.
b.
To evaluate a real-world example where median represents the best data.
b.
Answer to Problem 10PPS
Average marks of a class is taken out by taking out there median.
Explanation of Solution
Given:
Median.
Concept Used: Advantages and disadvantages of median.
The median also shows an average but it’s a different kind of average. Unlike mean, median is not affected by a highly skewed data. The average marks of a class is taken out by calculating there median. Median is a nest measure to calculate the center of a grouped data.
Conclusion:
Average marks of a class is taken out by taking out there median.
c.
To evaluate a real-world example where mode represents the best data.
c.
Answer to Problem 10PPS
The school/ college topper is calculated by mode.
Explanation of Solution
Given:
Mode.
Concept Used: Advantages and disadvantages of mode.
The mode shows the maximum value or the most occurring value. Hence, to find the school topper mode is used, as for that we need to find the student with maximum marks. Mode helps in finding the student with maximum marks.
Conclusion:
Average marks of a class is taken out by taking out there median.
