Statistical Formulas
Statistical analysis is a key aspect of data management. Excel offers a range of statistical formulas that can help you analyze your data more effectively.
- STDEV: Calculates the standard deviation of a sample.
- STDEVP: Calculates the standard deviation of an entire population.
- VAR: Calculates the variance of a sample.
- VARP: Calculates the variance of an entire population.
- PERCENTILE: Returns the value at a specific percentile.
Text Formulas
Text formulas in Excel are useful for manipulating text data, such as concatenating strings, extracting parts of text, and searching for specific text within a cell.
- CONCATENATE: Combines two or more text strings into one.
- TEXTJOIN: Combines text from multiple ranges, with an optional delimiter.
- LEFT: Extracts a specified number of characters from the left side of a text string.

- IF: Tests a condition and returns different values depending on whether the condition is TRUE or FALSE.
- AND: Returns TRUE if all the conditions are TRUE.
- OR: Returns TRUE if at least one of the conditions is TRUE.
- NOT: Reverses the logical value of a condition.
- ISBLANK: Checks if a cell is blank.
Lookup and Reference Formulas
Lookup and reference formulas are used to retrieve data from one part of a worksheet and display it in another. These formulas are essential for data validation and data manipulation.
- VLOOKUP: Searches for a value in the first column of a table and returns a value in the same row from a specified column.
- HLOOKUP: Searches for a value in the first row of a table and returns a value in the same column from a specified row.
- INDEX: Returns the value of a cell in a specific row and column within a range.
- MATCH: Searches for a specified item in a range and returns the relative position of that item.
- CHOOSE: Returns a value from a list of values based on a specified index number.
Financial Formulas
Excel's financial formulas are designed to help you perform calculations related to investments, loans, and other financial matters.
- NPV: Calculates the net present value of an investment.
- IRR: Calculates the internal rate of return for a series of cash flows.
- FV: Calculates the future value of an investment.
