Generating Random Times for Events

Generating Random Times for EventsIf you are ever in the need for sample data where the events (sales, support calls, etc.) occur several times throughout any given day, here is a neat little trick to accomplish that. One might think the RANDBETWEEN function, which generates a random integer between two numbers that you feed the function, would do the trick. Well, because RANDBETWEEN only returns whole numbers, the time of the day is always going to be at midnight.

To add increments that are less than one day, you would need to add numbers less than one (i.e. not whole numbers). For example adding 0.25 would take the time to 6 am; 0.5 to noon, and 0.75 6 pm. Luckily, adding a number less than one is easy. The RAND function, which generates a number between 0 and 1, does all of the work you.

To generate a list of random times, then, simply start with whatever date you wish in the first row of your data. All is needed in each cell afterward is the addition of Rand(). After adding Rand() to the previous cell, simply copy (or drag) the formula for as many entries as you wish. See attached for example. If, when you’ve finished the copying/dragging, you don’t see enough entries in each day (only 6 am, 2 pm, and 11:30 pm— 3 entries—for example), simply divide Rand() by 2 (or 3 or 4 or 5), to make the increment each time smaller. Pretty straightforward, huh?

Pivot Tables.. but first

I’ve been asked by many of you to put together something on Pivot Tables.  In doing so, I found the hardest part was compiling sample data that allowed me to highlight some of the cool features that Pivot Tables have to offer. After searching the web for sample data to use and coming up empty, I decided to go the long route and just start typing.  But as luck would have it, I stumbled upon a slick way or two to generate some useful data.  Attached is that discovery in two parts.  This is my first attempt at a video blog, so please provide any feedback, good or bad.
