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

Answer :

 

The answer is 7.5.

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
