<h3>Mean is 4.818</h3><h3>Mode is 4</h3><h3>Median is 4</h3>
<em><u>Solution:</u></em>
<em><u>Given data set is:</u></em>
2,3,1,4,4,3,4,12,15,1,4
<em><u>Find Mean:</u></em>
The average of all the data in a set is mean
![Mean = \frac{\text{sum of all data}}{\text{number of data}}\\\\Mean = \frac{2+3+1+4+4+3+4+12+15+1+4}{11}\\\\Mean = \frac{53}{11}\\\\Mean = 4.818](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B%5Ctext%7Bsum%20of%20all%20data%7D%7D%7B%5Ctext%7Bnumber%20of%20data%7D%7D%5C%5C%5C%5CMean%20%3D%20%5Cfrac%7B2%2B3%2B1%2B4%2B4%2B3%2B4%2B12%2B15%2B1%2B4%7D%7B11%7D%5C%5C%5C%5CMean%20%3D%20%5Cfrac%7B53%7D%7B11%7D%5C%5C%5C%5CMean%20%3D%204.818)
<em><u>Find mode:</u></em>
The value which occures most frequently in a data set is mode
In given data set,
4 occurs frequently ( 4 times )
Thus mode of data set is 4
<em><u>Find median</u></em>
The value in a set which is most close to the middle of a range.
Order the number in ascending order
1, 1, 2, 3, 3, 4, 4, 4, 4, 12, 15
Here, 4 is the middle number in set
Thus medain is 4
