Which formula to bucket range of numbers

I have a column of random numbers. In a second column I want to group these numbers by creating a text that reads 1-100, 101-200, 201-300 etc. This will greatly reduce the number of rows of data and make pivot table more effeciently.

6 1-100
234 201-300
188 101-200
44 1-100
1123 1101-1200

Answer: Which formula to bucket range of numbers

To bucket range of numbers in Excel, you can use the following formula:

Formula:
``` =IF(A1<=100,"1-100",IF(A1<=200,"101-200",IF(A1<=300,"201-300",IF(A1<=400,"301-400",""))))  ```
Here, A1 is the cell reference of the first number in your column. You can adjust the ranges as per your requirement.

Follow these steps to apply the formula:
1. In the second column, click on the first cell where you want to apply the formula.
2. Type the formula mentioned above in the formula bar.
3. Press Enter to apply the formula to the cell.
4. Now, click and drag the fill handle of the cell to apply the formula to the remaining cells in the column.

This will bucket the range of numbers in the second column as per the specified ranges. You can now use this column to create a pivot table and analyze your data more efficiently.

Which formula to bucket range of numbers

Enter in B1 and copy down...

=(ROUNDDOWN(A1/100,0)*100)&" - "&((ROUNDDOWN(A1/100,0)+1)*100)

assuming your data is in COL A

Hi

Why not leave your data as it is, and retain the accuracy, but in the PT
Group the data in bands of 100

Have over 30,000 lines of data and need to summarize totals into into smaller pre-defined groupings.

Bucket analysis in Excel

You can use the data analysis toolpak that comes built in, but needs to be enabled to be used. See http://office.microsoft.com/en-us/ex...215691033.aspx

Once you load the toolkit, the "bucket" analysis you want to do can be done with the Histogram tool. Here's a snip from the help for that tool:

"The Histogram analysis tool calculates individual and cumulative frequencies for a cell range of data and data bins. This tool generates data for the number of occurrences of a value in a data set.

For example, in a class of 20 students, you can determine the distribution of scores in letter-grade categories. A histogram table presents the letter-grade boundaries and the number of scores between the lowest bound and the current bound. The single most-frequent score is the mode of the data.

Histogram dialog box
Input Range Enter the cell reference for the range of data that you want to analyze.

Bin Range (optional) Enter the cell reference to a range that contains an optional set of boundary values that define bin ranges. These values should be in ascending order. Microsoft Office Excel counts the number of data points between the current bin number and the adjoining higher bin, if any. A number is counted in a particular bin if it is equal to or less than the bin number down to the last bin. All values below the first bin value are counted together, as are the values above the last bin value.

If you omit the bin range, Excel creates a set of evenly distributed bins between the data's minimum and maximum values. ..."

Setting the bin range to the bucket limits you want will sort the data as you want.

Which formula to bucket range of numbers

I made a revision based on marqs original question:

(ROUNDDOWN((A1-1)/100,0)*100)+1&" - "&((ROUNDDOWN((A1-1)/100,0)+1)*100)

This would probably bucket the outliers between intervals (i.e. 100, 300)
