Median of a column in R can be calculated by using median() function. Let’s see how to calculate Median in R with an example.
Let’s first create the dataframe.
### Create Data Frame
df1 = data.frame(Name = c('George','Andrea', 'Micheal','Maggie','Ravi','Xien','Jalpa'),
Grade_score=c(4,6,2,9,5,7,8),
Mathematics1_score=c(45,78,44,89,66,49,72),
Science_score=c(56,52,45,88,33,90,47))
df1
So the resultant dataframe will be
Get Median of the column in R
Method 1:
Get Median of the column by column name
# Get Median of the column by column name median(df1$Mathematics1_score)
Result:
[1] 66
Method 2:
Get Median of the column by column position
# Get Median of the column by column position median(df1[,3])
Result:
[1] 66
