Question

write the principle to find the median of ungrouped data.♥

Answer 1

Answer:

if the number of observation is odd then use n+1/2 if even use n/2 th observation+{n/2+1}th observation/2

Step-by-step explanation:

example : if 1,2,3,4,5 then use n+1/2

MEAN 5+1/2=6/2=3

example1,2,3,4,5,6

n=6

n/2 th obs + n/2+1 obs /2

6/2 th obs + 6/2 + obs/2

3th obs  + 4th obs /2

3+4/2=7/2 or 3.5

Answer 2

Answer:

The median refers to the middle data point of an ordered data set at the 50% percentile. If a data set has an odd number of observations, then the median is the middle value. If it has an even number of observations, the median is the average of the two middle values.
