To generate a random number between a and b, use this formula: RAND() * (b - a) + a
To generate random times in at specific intervals you can use the RAND function with the FLOOR function. In the example shown, the formula in B6 is:
which generates a random time at a...
To randomly assign people to groups or teams of a specific size, you can use a helper column with a value generated by the RAND function, together with a formula based on the RANK and ROUNDUP functions. In the example...
To generated a random number, weighted with a given probability, you can use a helper table together with a formula based on the RAND and MATCH functions.
In the example shown, the formula in F5 is:
