Use the XLOOKUP function to find things in a table or range by row. For example, look up the price of an automotive part by the part number, or find an employee name based on their employee ID. With XLOOKUP, you can look in one column for a search term and return a result from the same row in another column, regardless of which side the return column is on.
Example 5 uses a nested XLOOKUP function to perform both a vertical and horizontal match. It first looks for Gross Profit in column B, then looks for Qtr1 in the top row of the table (range C5:F5), and finally returns the value at the intersection of the two. This is similar to using the INDEX and MATCH functions together.
The backslash character (\) in a regular expression indicates that the character that follows it either is a special character (as shown in the following table), or should be interpreted literally. For more information, see Character Escapes.
Anchors, or atomic zero-width assertions, cause a match to succeed or fail depending on the current position in the string, but they do not cause the engine to advance through the string or consume characters. The metacharacters listed in the following table are anchors. For more information, see Anchors.
Grouping constructs delineate subexpressions of a regular expression and typically capture substrings of an input string. Grouping constructs include the language elements listed in the following table. For more information, see Grouping Constructs.

Substitutions are regular expression language elements that are supported in replacement patterns. For more information, see Substitutions. The metacharacters listed in the following table are atomic zero-width assertions.
Miscellaneous constructs either modify a regular expression pattern or provide information about it. The following table lists the miscellaneous constructs supported by .NET. For more information, see Miscellaneous Constructs.
Most importantly, Z-score helps to calculate how much area that specific Z-score is associated with. A Z-score table is also known as a standard normal table used to find the exact area. The Z-score table tells the total quantity of area contained on the left side of any score or value (x).
So, this is how you calculate the Z-Score of any given range. Similarly, if you're working with a lot of data in a spreadsheet, you can use the XLOOKUP function in Excel when you need to find something in a table or range.
These files contain the L, M, and S parameters needed to generate exact percentiles and z-scores along with the percentile values for the 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 97th percentiles by sex (1=male; 2=female) and single month of age. The smoothed 85th percentile values are included in the BMI-for-age and weight-for-stature tables. Age is listed at the half month point for the entire month; for example, 1.5 months represents 1.0-1.99 months or 1.0 month up to but not including 2.0 months of age. The only exception is birth, which represents the point at birth. To obtain L, M, and S values at finer age or length/stature intervals interpolation could be used.
where the L, M, and S are the values from the appropriate table corresponding to the age in months of the child (** indicates an exponent, such that M(1+LSZ)**(1/L) means raising (1+LSZ) to the (1/L)th power and then multiplying the M; exp(X) is the exponentiation function, e to the power X). Z is the z-score that corresponds to the percentile. z-scores correspond exactly to percentiles, e.g., z-scores of -1.881, -1.645, -1.282, -0.674, 0, 0.674, 1.036, 1.282, 1.645, and 1.881 correspond to the 3rd, 5th, 10th, 25th, 50th, 75th, 85th, 90th, 95th, and 97th percentiles, respectively.
For example, to obtain the 5th percentile of weight-for-age for a 9-month-old male, we would look up the L, M and S values from the WTAGEINF table, which are L=-0.1600954, M=9.476500305, and S=0.11218624. For the 5th percentile, we would use Z=-1.645. Using the equation above, we calculate that the 5th percentile is 7.90 kg.
where X is the physical measurement (e.g. weight, length, head circumference, stature or calculated BMI value) and L, M and S are the values from the appropriate table corresponding to the age in months of the child (or length/stature). (X/M)**L means raising the quantity (X/M) to the Lth power.
For example, to obtain the weight-for-age z-score of a 9-month-old male who weighs 9.7 kg, we would look up the L, M and S values from the WTAGEINF table, which are L=-0.1600954, M=9.476500305, and S=0.11218624. Using the equation above, we calculate that the z-score for this child is 0.207. This z-score corresponds to the 58th percentile.
This spreadsheet contains calculators that determine a critical t-value for a given alpha and that determine a probability for a given t-value. It also provides a Student's t table of critical values for a two-tailed test and for a one-tailed test at various levels of significance
This spreadsheet contains calculators that determine the critical r for a given alpha and that determine the p-value for a given r. It also provides a table of critical values for two-tailed tests at various levels of significance
Select the links below to see commonly referenced tables. Within the links are explanations and examples. BE CAREFUL when using tables. There are many variations and all can be correct but only when interpreted correctly. Some tables are for one-tailed test and others cover two-tailed test.
The conversion table below is similar to the one above but lets discuss the differences. It is very important to remember that DPMO and PPM may or may not be the same. Lets use an exaggerated example to illustrate a point.If ONE part has 1,000,000 opportunities for a defect, and one defect is found that makes the entire PART a defective PART.So it is possible that you could have 1 PPM with a DPMO of 0.000001.Also, Cpk is estimated from the sigma level and it isn't always an exact match since the Cpk calculation takes the better of the USL or LSL and doesn't consider the tail of the opposite tail.It is most important to understand the basic relationships and memorize the most common levels of sigma, estimated Cpk, and yields for normal distributions.Also, if a process is CENTERED, then Cp = Cpk.
Returns the standard normal cumulative distribution function. The distribution has a mean of 0 (zero) and a standard deviation of one. Use this function in place of a table of standard normal curve areas.
Enter the values 100,2,96,104 below m, S.D, x1, x2 respectively. These values are usually given to you in questions. Below Z1 we will calculate the standard score of X1. There are two ways to do this, either using the formula we learned in class (X-m)/σ or using the excel function STANDARDIZE(x, mean, S.D). Choose either one of them.

As you can see in the sorted table on the right, the related information in each row is kept together:In some situations, mostly when just one or a few cells in the middle of your data set are selected, Excel is unsure which part of the data to sort and asks for your instructions. If you'd like to sort the entire dataset, leave the default Expand the selection option checked, and click Sort:Note. In this tutorial, a "table" is just any data set. Technically, all our examples are for ranges. Excel table has inbuilt sorting and filtering options.
Excel will sort your data in the specified order. As shown in the screenshot below, our table is arranged alphabetically exactly as it should: first by Region, and then by Name:Tip. If the items you want to sort contain both text and numbers, check out How to sort mixed numbers and text in Excel.
As the result, the first row in our table is sorted in alphabetical order, and the rest of the data is rearranged accordingly, preserving all correlations between the entries:Problems with sorting alphabetically in ExcelExcel sort features are amazing, but if you are working with an imperfectly structured data, things may go terribly wrong. Here are the two common issues.
An easy fix is to eliminate the blanks and unhide all hidden areas before sorting. In case of blank rows (not hidden rows!), you can select the entire table first, and then alphabetize.Unrecognizable column headersIf your column headers are formatted differently from the rest of the data, Excel is smart enough to identify them and exclude from sorting. But if the header row has no special formatting, your column headers will most likely be treated as regular entries and end up somewhere in the middle of the sorted data. To prevent this from happening, select only the data rows, and then sort.When using the Sort dialog box, make sure the My data has headers checkbox is selected.How to sort alphabetically in Excel with formulasMicrosoft Excel provides a variety of features to cope with many different tasks. Many, but not all. If you are facing a challenge for which there is no built-in solution, chances are it can be accomplished with a formula. It is also true for alphabetical sorting. Below, you will find a couple of examples when alphabetical order can only be done with formulas.
