Question

What are the mean, median, and mode of the following numbers?: 1,4,5,6,10,25?

Answer 1

Let `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`

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.
