Excel tip:

Use RANDBETWEEN to generate random numbers

There may be occassions where you need to generate random numbers in your spreadsheet. Use the RANDBETWEEN function to generate random numbers between two values that you specify.

The function looks like this:

=randbetween(LOW,HIGH)

where LOW is the lowest number you want generated; and HIGH is the highest number you want generated.

This formula will work with both positive and negative LOWs and HIGHs. Also it will only generate integer numbers unless forced to do otherwise by the following:

=randbetween(LOW*10^PRECISION,
HIGH*10^PRECISION)/(10^PRECISION).

where PRECISION represents the levels of decimal precision needed (i.e. if you need numbers with one decimal place, PRECISION would be 1; 2 for two decimal places and so on).

One final note, if the RANDBETWEEN formula does not work in your spreadsheet or returns a "#NAME" error, you need to install the Analysis Toolpak Add-In. You will need to press F2 then Enter following the installation.
