Let S=[1,4,5,6,10,25}S=[1,4,5,6,10,25}

The mean or average is bar x=1/nsum_(i=1)^nx_i=1/6(1+4+5+6+10+25)=8,5¯x=1nni=1xi=16(1+4+5+6+10+25)=8,5

The median is the middle data point, or in this case, since the number of data points is even, the median is the average or mean of the 2 middle points.
therefore median = (5+6)/2=5,5

The mode is the number that occurs most frequently and so since here every number occurs only once, the mode is undefined.
