Predicting dataset


Suppose that you have 3 datasets of varying numbers from a device. Lets say one has a range from 30-50, another has a range from 40-70, and the last one has a range from 65-80. The numbers here doesn't matter, but it illustrates my point. Each dataset holds 25 numbers.

Each dataset received its numbers from a device reading signal strengths. You the the standard deviation, the max and min and mean of each dataset. If you were to run the device again, but only collecting 5 numbers this time. How can you compare those 5 numbers with the numbers from the 3 datasets to determine which dataset it should be a part of?

I hope that question was clear. Thanks for any help!
