2 median formulas for single data in statistics

The median is the middle value of a group of data that has been sorted by magnitude.

The median formula for single data in statistics

there are two formulas to determine the median of a data, The following is the median formula for a single data:

1. The median formula if a lot of data is odd

Me = data location : (n + 1)/2

Information :

Me = Median Value

n = amount of data

Example :

Please determine the median of the data 3,7,6,4,5 !

Answer:

n = 5

The first thing to do is sort the data, so the data becomes 3,4,5,6,7

after that set the median :

Me = data location : (n + 1)/2

Me = data location : (5 + 1)/2

Me = data location : 6/2

Me = data location : 3

So the median of data is in the third location :

first location = 3

second location = 4

third location = 5

fourth location = 6

fifth location = 7

Me = Median location : 3 = third location = 5

So the median of 3, 7, 6, 4, and 5 is 5

2. The median formula if a lot of data is even

Me = ((data location : n/2) + (data location : ((n/2) + 1))2

Information :

Me = Median Value

n = amount of data

Example :

Please determine the median of 1, 2, 4, and 3 !

Answer :

n = 4

first location = 1

second location = 2

third location = 3

fourth location = 4

The first thing to do is sort the data, so the data becomes 1, 2, 3, 4

after that set the median :

Me = ((data location : n/2) + (data location : ((n/2) + 1))) / 2

Me = ((data location : 4/2) + (data location : ((4/2) + 1))) / 2

Me = ((data location : 2) + (data location : (2 + 1))) / 2

Me = ((data location : 2) + (data location : 3)) / 2

Me = (second location + third location) / 2

Me = (2 + 3) / 2

Me = 5 / 2

Me = 2,5
