Welcome to Catalytic, blog to share questions about Education. This time we will answer questions and at the same time we will discuss the following questions: **Look at the following data 4 9 5 7 4 7 6 10 10 7 8 3 The median of the data is**

Known one **data** that is:

- 4, 9, 5, 7, 4, 7, 6, 10, 10, 7, 8, 3.

**Median **from **data** it is **7**. We get these results by sorting the data from smallest to largest and then find the middle value.

### Explanation with steps

**Median **is the middle value of the data that has been sorted from smallest to largest. If n is the amount of data, then the formula for the median is:

- Me = data to ½(n + 1), for n odd numbers.
- Me = ½ (data to ½n + data to (½n + 1)), for n number even.

**Is known **

4, 9, 5, 7, 4, 7, 6, 10, 10, 7, 8, 3.

**asked**

Determine the median of the data!

**Java**

**Step 1**

Data: 4, 9, 5, 7, 4, 7, 6, 10, 10, 7, 8, 3 we sort from smallest to largest to:

- 3, 4, 4, 5, 6, 7, 7, 7, 8, 9, 10, 10.

**Step 2**

The amount of data is 12 (n = 12), so we use the median to determine it formula for n even numbers.

Me = ½ (data to ½n + data to (½n + 1))

= ½ (data to ½ (12) + data to (½ (12) + 1))

= ½ (6th data + (6 + 1) data)

= ½ (6th data + 7th data)

= ½ (7 + 7)

= ½ (14)

= 7

**Step 3**

Another way is to look directly at the middle value of the data that has been sorted, namely:

3, 4, 4, 5, 6, **7 | 7**, 7, 8, 9, 10, 10

median

We can see that the middle or median value lies between 7 and 7, which is equal to 7. So **the median of the data** it is 7.
