Generating Random Numbers in Excel

Technology for Teachers and Students


Summary

The video demonstrates how to generate random numbers in Excel using the Rand function for decimal values and the Randbetween function for whole numbers within specified ranges. It emphasizes the use of the autofill handle to quickly create a series of random numbers. To maintain stable random values, one can copy and paste the values as values to prevent recalculation. Additionally, it mentions converting random numbers to percentages and organizing the Excel sheet for better presentation.


Generating Random Numbers between 0 and 1

To generate random numbers between 0 and 1 in Excel, use the Rand function by typing =RAND() in a cell. You can autofill to get a series of random numbers.

Autofill Handle for Series of Random Numbers

Utilize the autofill handle to easily create a series of random numbers in Excel by clicking and dragging the cell with the Rand function.

Generating Random Whole Numbers within a Range

For whole numbers between specified ranges, use the Randbetween function by typing =RANDBETWEEN(1,5000) for example. You can then autofill to get a series of whole random numbers.

Stopping Recalculation of Random Numbers

To stop random numbers from recalculating, copy the values of the random numbers to a new column using paste special as values. This ensures the numbers remain stable.

Finalizing Random Numbers

Convert the stable random numbers to percentages if needed, and organize your Excel sheet by copying and pasting the stable random numbers, removing the original randomized column.
