Standard deviation is a measure of how much variance there is in a set of numbers compared to the average (mean) of the numbers. The STDEVA function is meant to estimate standard deviation in a sample. If data represents an entire population, use the STDEVPA function. In the example shown, the formula in E5 is: Standard Deviation functions in Excel The table below summarizes the standard deviation functions provided by Excel....

The VALUETOTEXT function takes two arguments: value and format. Value is the value to convert to text. The format argument controls the structure of the output. By default, format is zero and VALUETOTEXT will output a “concise” format text value, essentially the normal format that Excel will use to display any text value. When format is set to 1 (strict format), text values will be enclosed in double quotes ("")....

In this tutorial, I will show you 2 methods to do this. And none of it would take more than a minute. Method 1 – Using Text to Column This is the easiest way if the data has a pattern. For example, in email id, there would always be a username, followed by ‘@’, and ends with the domain name. The trick is to extract the text before the @ sign....

In the example shown, the formula in C5 is: Working from the inside out, the original text in B5 is flooded with spaces using SUBSTITUTE: This replaces each single space with 99 spaces. Note: 99 is just an arbitrary number that represents the longest word you need to extract. Next, the FIND function locates the specific character (in this case, “@”) inside the flooded text: FIND returns the position of the “@” in this text, from which 50 is subtracted....

Syntax FALSE() There are no arguments for this function. Example In this example we return the FALSE value.

where data (B5:D15) and temp (C5:C16) are named ranges . SEQUENCE is configured to create an array of 3 rows x 1 column. The step value is -1, and the start number is defined by this snippet: Here we are counting temp values less than 75. Because the named range temp contains twelve values, the result is an array of 12 TRUE and FALSE values: The double negative (–) is used to coerce the TRUE and FALSE results to 1s and 0s, and the SUM function returns the total: This number is returned directly to SEQUENCE for the start value....

As the formula is copied down, the TEXT function extracts a month name from each date in column B. To extract the month name from a date as text, you can use the TEXT function with a custom number format like “mmmm”, or “mmm”. In the example shown, the formula in cell C4 is: The TEXT function converts values to text using the number format that you provide. Note that the date is lost in the conversion: only the text for the month name remains....

There are two primary ways to concatenate in Excel: In the article below, I’ll focus first on manual concatenation with the ampersand operator (&), since this should be your go-to solution for basic concatenation problems. Then I’ll introduce the three Excel functions dedicated to concatenation: CONCATENATE, CONCAT, and TEXTJOIN. These functions can make sense when you need to concatenate many values at the same time. As with so many things in Excel, the most important thing is to understand the basics first....

Let’s take a look. Here we have some examples of information we want to change. In the first example, we want to increase prices by 10%. Obviously, we could just add a new formula that multiplies the existing price times 1.1 in another column. Then use Paste Special to paste over the original prices. But how can we do this without all that busy work? One way is to use Paste Special....

A lot of times, I convert his queries into Excel tutorials on this site, as it could be helpful for my other readers as well. This is also one such tutorial. My friend called me last week with the following issue: There is address data in a column in Excel, and I want to identify/filter cells the where the address has duplicate text strings (words) in it. Here is the similar dataset in which he wanted to filter cells that have a duplicate text string in it (the ones with red arrows):...

A simple example of this could be to analyze how many students scored marks between 40 and 50 and how many got marks between 50 and 60 and so on.. Another example could be to create a frequency distribution of age of a group of people. This would help in identifying how many people fall in the 30-40 age group and how many in 40-50 age group and so on....

For example, let’s say we use VLOOKUP to lookup the price for “green” in the data below. Which price will we get? Read on for the answer and more interesting examples. Notes: The examples below use named ranges (as noted in the images) to keep formulas simple. Function reference links: VLOOKUP, INDEX, MATCH, and LOOKUP. Exact match = first When doing an exact match, you’ll always get the first match, period....

A Pareto chart plots the distribution of data in columns by frequency, sorted in descending order. A line showing cumulative percentage is plotted on a secondary axis. Starting with Excel 2016, the Pareto chart is a built-in chart type. In this worksheet, I’ve got a list of 100 reported issues classified by type. There are six types total, listed in column E. To plot this data in a Pareto chart, we first need a summary count by type....

When to use Excel AVERAGE Function AVERAGE function can be used when you want to get the average (arithmetic mean) of the specified arguments. What it Returns It returns a number that represents the average (arithmetic mean) of the arguments. Syntax =AVERAGE(number1, [number2], …) Input Arguments number1 – the first number, cell reference, or range for which you want the average. [number2] – (Optional) the second number, cell reference or range for which you want the average....

When to use Excel AVERAGEIFS Function Excel AVERAGEIFS function can be used when you want to get the average (arithmetic mean) of all the cells in a range that meets multiple criteria. What it Returns It returns a number that represents the average (arithmetic mean) of the arguments. Syntax =AVERAGEIFS(average_range, criteria_range1, criteria1, [criteria_range2, criteria2], …). Input Arguments average_range – the range of cells you want to average. criteria_range1, criteria_range2,.. – the ranges against which the criteria are evaluated....

When to use Excel MID Function MID function can be used to extract a specified number of characters from a string. What it Returns It returns the sub-string from a string. Syntax =MID(text, start_num, num_chars) Input Arguments text – the text from which you want to extract the string. start_num – the starting position within the text argument, from where the extraction should begin. num_chars – the total number of characters that you want to extract....

And many of these are simply awesome. The amount of work you can get done with a few formulas still surprises me (even after having used Excel for 10+ years). And among all these amazing functions, the INDEX MATCH functions combo stands out. I am a huge fan of INDEX MATCH combo and I have made it pretty clear many times. I even wrote an article about Index Match Vs VLOOKUP which sparked a little bit of debate (you can check the comments section for some firework)....

As the formula is copied down, the numbers in column B are padded with a progressively larger number of zeros based on the number in column C. Note that the result is a text value. Fixed number The TEXT function returns a number formatted as text, using the number format provided. The TEXT function can apply number formats of any kind to numbers. It is most often used when you want to maintain number formatting for a number when concatenating that number with other text....

In the example shown, the formula in E4 is: replaces only the 2nd instance (2 comes from D4) of “x” in text in B4, with “~” character. The result looks like this: 100x15~50 Next, FIND locates the “~” inside this string and returns the position, which is 7 in this case. Note: we use “~” in this case only because it rarely occurs in other text. You can use any character that you know won’t appear in the text....

In the example shown, the formula in I5 is: Which returns the number 4, representing the position in this list of the the most expensive property. In this case, that value is 849900. This number is then supplied to the MATCH function as the lookup value. The lookup_array is the same range C3:C11, and the match_type is set to “exact” with 0. With those arguments, MATCH locates finds the maximum value inside the range and returns the relative position of the value in that range....
