Question

What is the value of middle-most observation(s) called?
A. Mean
B. Median
C. Mode
D. None of these

Answer 1

Hint: First recall the definitions of mean, median and mode, then observe by the definition which one is the required answer.

Complete step by step solution: The mean is actually the average of numbers, so to find the mean of n numbers take the sum of all the numbers and divide them by n.
Place the numbers in value order to find the middle number, that is the value of the median.
When there are two middle terms, then obtain the median of those two numbers to obtain the median of the data set.
The value that is found mostly in the data set is the mode.


Option ‘B’ is correct

Additional Information: Mean: Mean is the average of observations of the given data. The mean is calculated by dividing the sum of all observations by the number of observations.
Median: Median is the central observation. The median is the middle observation when the data arranges in ascending or descending order.
Mode: Mode of a data is an observation that is occurred maximum time. In other words, the observation that is repeated maximum times is mode of the data.

Note: Students sometimes write the answer directly, but that is not the correct way to answer the question, first write the definition and explain a little then write the correct option.
