the arithmetic average which is 1/9(3+4+5+5+6+7+10+11+12)=19×63=7

Mode is 5, median is 6 and mean is 7

.

Let us write the given data points in increasing order. These are

{3,4,5,5,6,7,10,11,12}

 

Now mode is the data point which appears most time and it is clearly 5

.

Median is the data point which appears exactly in the center when data is arranged in increasing order. As there are 9

data points already arranged in increasing order, median is the value of middle i.e 5th data point (equal to 9+12=5. Hence median is 6

.

Mean is the arithmetic average which is 19(3+4+5+5+6+7+10+11+12)=19×63=7

Hence, Mode is 5

, median is 6 and mean is 7.
