1 Add them together and divide by two for the median value. ( 2 If the two numbers in the middle are the same, that number is your median.) If you're working with the numbers 1, 2, 5, 3, 7, and 10, then your two middle numbers are 5 and 3. 3  Add up 5 and 3 to get 8 and divide this result by 2 to get 4 as your mode.

Randomization is the process of making something random; this can mean: Generating a random permutation of a sequence (such as when shuffling cards). Selecting a random sample of a population (important in statistical sampling). Generating random numbers: see Random number generation. Applications Edit. Randomization is used extensively in the field of gambling. Imperfect randomization may allow a skilled gambler to have an advantage, so much research has been devoted to effective randomization. A classic example of randomization is shuffling playing cards.
The term randomized trials omits mention of controls and can describe studies that compare multiple treatment groups with each other (in the absence of a control group). This type of randomization can be combined with stratified randomization, for example by center in a multicenter trial, to ensure good balance of participant characteristics in each group.. 2  A special case of permuted-block randomization is random allocation, in which the entire sample is treated as one block.
