Put all the numbers in numerical order.
If there is an odd number of results, the median is the middle term.
If there is an even number of results, the median will be the mean of the two central numbers.
122, 130, 115, 145, 132, 146, 149, 133, 140, 144.
arrange it in the increasing order 115,122,130,132,133,140,144,145,146,149
there are even no of terms therefore median= mean of the two central number =(133+140)/2 =136.5
median=136.5
