If you would like a column of evenly-spaced values, such as for frequency bins, Excel can fill them in for you. Put the first two values in and highlight those two cells. Click on the lower right-hand corner and drag downward; Excel will continue the pattern you began.
Use the following steps to present this data in a frequency distribution table. 1  Divide the results (x) into intervals, and then count the number of results in each interval. 2  In this case, the intervals would be the number of households with no car (0), one car (1), two cars (2) and so forth. Create a table similar to the frequency distribution table but with three extra columns. 2  In the first column or the Lower value column, list the lower value of the result intervals. 3  For example, in the first row, you would put the number 35.
