Question

find the mean median and mode 15,3, 11, 15,1,14,7,2,1,1,2

Answer 1

well, the mode is what's most often and that's:
1
the mean is:
6.5454545454545
the median is: 
3

Answer 2

Answer:  Median = 3, Mean = 6.45, Mode = 1.

Step-by-step explanation:

Since we have given that

15,3, 11, 15,1,14,7,2,1,1,2

As we know the formula for "Mean" :

$Mean=\frac{15+3+11+15+1+14+7+2+1+1+2}{11}\\\\Mean=6.45$

Mean = 6.45

Similarly, we know the formula for "Median":

First we write it in ascending order:

1,1,1,2,2,3,7,11,14,15,15

$Me=(\frac{n+1}{2})^{th}\\Me=\frac{11+1}{2}^{th]\\Me=\frac{12}{2}^{th]\\Me=6^{th}\\Me=3$

Median = 3

Mode is the number which has occurred mostly, has the highest frequency.

Mode = 1

Hence,  Median = 3, Mean = 6.45, Mode = 1.
