Basic functions : sumif

This short tutorial illustrates the two basic ways that SUMIF can be used in a spreadsheet.

The SUMIF function takes two or three arguments.

For the two argument version, the condition is applied to each cell in the range being SUMmed. In the example below, C9 is the sum of all values in C3:C8 that are greater than 5.

In the three argument version, the condition is applied to a separate range of cells. This range can be numerical of textual. In the example below, the values corresponding to Tom are summed in C10

Cell Counting 1: countif

September 8th, 2004

One of the most useful and versatile builtin functions in OOo Calc, with a bit of creativity, you can use for a slew of tasks…

How many cells in a given range are negative. =COUNTIF(A1:A20;”<0")

How many cells have the string “Yes”. =COUNTIF(A1:A20;”Yes”)

Don’t forget to include the quotation marks around the condition argurment. Otherwise, you get an Err:510

Stefano Lenzi commented if you want that your criteria contains reference to other cells you can refer to the following example.

To count the cells less then A3: =COUNTIF(”A1:A20″;CONCATENATE(”<";A3))

Ranking and sorting data I

April 25th, 2005

Computing the rank order of entries in an array of data is needed in many applications.

There are a number of builtin OOo functions that deal with the ranking and ordering of data. We will look at four - RANK, PERCENTRANK, PERCENTILE, and LARGE

In the example below, we see two variants of RANK wherein the entries can be ordered in descening or ascending order. The first two arguments of RANK are the value to be ranked and the array that contains the data. By default, with these two arguments, the entries will be ranked in descending order. The optional third argument - when set to 1 - ranks the entires in ascending order.

The PERCENTRANK function assigns a percentage value to a given value based on a 100% range between the minumum and maximum values of the specified range. If you don’t format these results as a percentage value, the output from PERCENTRANK will lie betwen 0 and 1.

The PERCENTILE function accepts a percentage value as input and returns the percentile of data values in an array. A percentile returns the scale value for the array which goes from the smallest (%age=0) to the largest value (%age=1) of the array. The 50% percentile of an array is the same as the MEAN.

Conditional summation revisited

April 20th, 2005

For OOo 2.0, enhanced functionality seems to have been introduced with respect to using array formulas for conditional summation. Consider the example below, where we wish to total numbers in a column corresponding to a particular month.

Contrast this with the use of SUMIF in a previous tip. We have also covered SUMPRODUCT before

Now, the SUM IF and SUMPRODUCT constructs shown below accept a function of an array. MONTH normally accepts a single date as a parameter - but within an array formula as in the examples below, it makes more sense to be able to apply an array of dates to MONTH. This has always been possible in Excel.

It seems, OOo Calc continues to match and/or surpass Excel in functionality - which can onloy be a good thing for those who wish to migrate from Excel.
