All data entered into cells formatted as text become text, even if you meant for them to be numbers or dates. Perhaps headings are an exception to this rule.įormat cells as text only when completely necessary. If you have altered the default alignment, you will be left scratching your head. It is very common for people to reference cells, which look like numbers but in reality are text. If you start changing this formatting, you will not be able to tell at a glance if the contents of a cell are text or numeric. By default, numbers in Excel are right-aligned and text is left-aligned, and there are good reasons to leave it this way. People also tinker with the alignment of cell data. These can then be used for criteria for features such as Advanced Filter and Database functions. It is always a good idea to leave at least three blank rows above your table ( at least three, preferably more).

Some very good universal colors to consider using in your spreadsheets are black, white, and gray. Often the overuse of formatting adds size to your workbook, and although your workbook might look like a work of art to you, it might look terrible to someone else. Although they don’t necessarily realize it, this time frequently comes at the expense of efficiency. We are big believers in ' keeping it simple.” Far too many people spend tremendous amounts of time formatting their spread-sheets. Although a spreadsheet should be easy to read and follow, this should rarely be at the expense of efficiency.

Moving beyond structure, formatting also can cause problems. Sorting also will speed the calculation process of many functions significantly. Excel has a rich set of lookup and reference formulas, some of which require that your data be sorted in a logical order. Make sure your data is sorted whenever possible. If you find you are repeating the same data over and over for two or more rows in one of these columns, resist the temptation to use blank cells to indicate repetition. With this in mind, you should set up tables with column headings going across the first row of your table and related data laid out in a continuous manner directly underneath their appropriate headings. It is no coincidence that Excel spreadsheets can comprise 1,048,576 rows (65,536 pre-2007) but only 16,384 columns (256 pre-2007).

In such scenarios, you can use these features to their full potential only when you’ve laid out your data in a very basic table. Time and time again we see spreadsheets that do not follow this simple rule and thus are limited in their ability to take full advantage of some of Excel’s most powerful features, including PivotTables, subtotals, and worksheet formulas. The first three items on the preceding list add up to one thing: you should always try to keep related data in one continuous table. Having blank columns and rows in tables of data Unnecessarily spreading data over different tables Unnecessarily spreading data over numerous worksheets Despite its name, PERCENTILE requires a fraction, not a percentage.Unnecessarily spreading data over many different workbooks.The value with rank 0.75 lies proportionately between 3 and 7, and is calculated as 3 + (7-3)*0.75 = 6. The lowest number 3 is assigned rank 0 the next highest number 7 is assigned rank 1. The rank of the value to be found is 0.25 * (4-1) = 0.75. The next two examples illustrate the calculation, but are not intended to show practical application: PERCENTILE(A2:A99 0.6) where cells A2:A99 contain scores from a test, returns the score below which 60% of the scores lie. PERCENTILE returns the maximum, median, minimum value when fraction is 1, 0.5, 0 respectively. It is of limited use with a small list of numbers. This function may be useful for example when determining a score below which lies a certain percentage of all scores for a test.

If r is integer the corresponding value from numberlist is returned otherwise the value is calculated proportionately between the values with rank | r| and | r|+1 (see the examples). The rank r of the value to be found is fraction * ( N-1), where N is the count of numbers in numberlist. PERCENTILE internally assigns a rank to each number in numberlist, where 0 is the rank of the lowest number, 1 of the next lowest and so on. fraction must be between 0 and 1 inclusive numberlist is a range or array of numbers, not necessarily in order. PERCENTILE(numberlist fraction) PERCENTILE returns the value below which fraction of the numbers in numberlist lie. Returns a specified percentile in a list of numbers.
