=__**1) Measures of Central Tendency**__=
 * __**Mean:**__To find the mean you add up all the numbers you have and then divide it by the amount of of numbers you put in.


 * [ example** : 2,3,4,5,6 . **:** 2+3+4+5+6= 20 **/** 5 = 4 . The mean is 4. **]**


 * **__Median:__** To find the median, you place all the numbers in numerical order. After that you look for the number in the center of the set of numbers.

However, there may also be an even amount of numbers in the set. Let's say you have the set : **2,3,4,5,6,7**. As you can see, there is **no** number in the center. So you take the **two** numbers that are located in the middle (4,5) and you **add** them. 4+5 . After that you divide it by 2. (4+5=9 / 2 = 4.5) The median is now **4.5** **]**
 * [ example** : 2,3,4,5,6 . : the median is 4.


 * **__Mode :__** To find the mode you look for the number that is repeated the most.

So let's say that you have the data set : 2,3,4,5,5,6,7. The mode is 5 because that is repeated the most. **]
 * [ example :** 2,3,4,5,6 : As you can see, there is no number that is repeated so there is no mode.

My Question :** Find the mean, median, and mode of the data set **2,3,5,5,7,10,12**
