The first quartile is defined as the middle number between the smallest number and the___ of the data set.
median
mean
mode
frequency
Consider the following observations regarding the median of a data set:
Observation I: The median is defined only for numerical data.
Observation II: For an odd number of data points, the median is the central value after rearranging, whereas for an even number of data points, the median is the mean of two central values after rearranging.
Observation III: Unlike mode, the median may or may not be the same as an existing data point.
To find the median we want to arrange data in ascending or desending order and the middle number is the median, if the no.of number are even we won't get middle number then what should we do?
What is the difference between the mean and median of first 11 natural numbers?
