# The median of the data is

Welcome to Catalytic, a blog to discuss the discussion of subject matter from Higher Education, High School, Middle School and Elementary Schools. This time Katalistiwa will discuss a question that is often asked in school exams. The questions are: The median of the data is

## The median of the data is

### Detailed discussion of the Median

Median is the middle value of an ordered data. If the number of data is n, then the median of the data is

• Me =data to ½ (n + 1)

To find the median from the question table above, we create another column with the title frequency cumulative (fk)

f fk value

5       3       3

6       5       3 + 5 = 8

7       2       8 + 2 = 10

8       4      10 + 4 = 14

9       6      14 + 6 = 20

So lots of data is n=20

From the table above, the meaning of fk is

• Value 5 is data 1 to 3
• Value 6 is data 4 to 8
• Value 7 is data 9th to 10th
• Value 8 is the 11th to 14th data
• Value 9 is the 15th to 20th data

the median is

=data to ½ (n + 1)

=to ½ (20 + 1)

= data to ½ (21)

= to 10.5

it means

The median lies between the 10th and 11th

= ½ (10th data + 11th data)

=½ (7 + 8)

= ½ (15)

=7,5
