## Basic Excel functions

Get ready to be an Excel master! **LOG: Excel Formulae Explained** will teach you the **Sum, Average, and Count** formulae. These functions are great for quickly computing data. Plus, they’ll help you arrange your spreadsheets like a pro!

### Sum formulae

Basic mathematical functions can aid you to accomplish your tasks quickly and efficiently in Excel. These mechanisms are programmed into the software to help you perform calculations with minimal effort. One of these mechanisms is the ‘**Addition formulae**‘ in Excel.

Adding values in sheets is a basic function of Excel, but executing this method could take time, considering how much data has been entered and how many cells you need to sum up. With the addition formulae or more commonly known as **SUM formulae**, you can add multiple figures within seconds without any difficulty.

The SUM formulae make it easier for you to **calculate a range of numbers by adding them up immediately**. Type “=SUM(” into an empty cell, highlight the relevant cells or rows, sort “)” then hit enter. The cell will automatically display the entire quantity that you desired.

It’s imperative to **double-check your sum formula for accuracy after applying it** before using it on massive amounts of data since even one wrong input while selecting the array could make all your hard efforts go down in vain.

Calculating averages in Excel is like finding a needle in a haystack, except with numbers instead of hay.

### Average formulae

When it comes to working with data in Excel, understanding how to calculate the average can be a crucial tool. By finding the **mean** of a set of numbers, you can quickly grasp an idea of their collective value. Excel provides several ways for you to achieve this task.

An easy method for determining average is with the **AVERAGE** function. After selecting the cells or range of data, use this formula to get your answer in just a few clicks. There are instances where you may have missing data points and need a pure representation of central tendency, utilizing **AVERAGEIF** will do just that.

Furthermore, for more granular control over your work process and analysis – **pivot tables** allows multiple fields as rows/columns and choice of aggregation types. With these options at your disposal, you’ll be well-equipped to navigate through varying datasets for insights.

According to Forbes (2015), nearly **85% businesses** rely on spreadsheets like Microsoft Excel for financial management tasks.

**Counting sheep** is outdated, use the **COUNT** formula in Excel to keep track of your data instead.

### Count formulae

For Quantifying Functions

To determine the number of implemented functions, it is vital to understand **‘Count formulae’**. Apply these simple yet effective steps to Count formulae:

- Click on the cell in which you wish to apply the logic.
- Input “
`=COUNT`

” into the formula bar, followed by a left bracket. - Select and include all cells that require counting.
- Finally, close with a right bracket and hit Enter.

Unique details that have not been covered previously include understanding how to differentiate between formulas and values within selected cells. Also, taking into account the potential impact of manual inputs or external changes affecting counts.

Suggested techniques could improve your counting efficacy when working with large datasets. Suggestions include, clear formatting for precise representations, periodic model updates for up-to-date statistics analysis, and grouping data according to specific criteria for a more granular perspective of operations performance.

Step up your game with these intermediate Excel functions, because basic Excel is just child’s play.

## Intermediate Excel functions

Advance your excel abilities and make work simpler. Get to know the intermediate Excel functions. **IF**, **VLOOKUP** and **INDEX-MATCH** formulae are some of them. These functions can reduce data analysis and manage data more productively. Brush up your excel formulae knowledge by checking out **‘LOG: Excel Formulae Explained’**. This section has all the intermediate functions you need!

### IF formulae

When working with data in Excel, using a formula to perform conditional calculations can be helpful. These types of formulas are commonly referred to as ‘logical functions.’

One such logical function is the **IF function**, which checks whether a condition is true or false and returns one value if it’s true and another value if it’s false. It can be used for tasks like calculating grades, determining eligibility for a discount, or identifying which products sold above a certain threshold.

To use the IF function, start with `=IF(logical_test,value_if_true,value_if_false)`

, where logical_test evaluates whether the condition is true or false and value_if_true returns the desired result if it’s true, while value_if_false returns the desired result if it’s false.

It’s important to note that nested IF functions can become complex and difficult to read, so consider using other logical functions like **AND, OR,** and **NOT** when appropriate.

By using these functions appropriately and efficiently, you can streamline your data analysis processes and quickly identify relevant information.

**VLOOKUP:** the Excel function that can finally answer the question ‘Is there any hope of finding what I’m looking for?’

### VLOOKUP formulae

For advanced spreadsheet tasks, use the **VLOOKUP** Excel function to search for data in a specific column and retrieve information from a corresponding row.

To better understand **VLOOKUP** formulae, let’s create a table with columns including Item Name, Price and Supplier. Using this function, we can locate a particular item in the list and return its related price or supplier information.

In addition to specifying lookup range, the VLOOKUP function uses four parameters: lookup value, table array, column index number and range lookup. Be careful when defining column index numbers as it determines which column of data is returned.

**Pro Tip:** To ensure accuracy in your VLOOKUP formulae, consider using named ranges instead of cell references for improved readability.

Say goodbye to **VLOOKUP**, hello to **INDEX-MATCH** – the Dynamic Duo of Excel function formulae.

### INDEX-MATCH formulae

- Use the
**INDEX**function to identify the target column or row in your table. - Within this function, specify the row number or column number you want to return data from using
**MATCH**. - In MATCH, specify the target value you’re searching for, and the range within which it can be found.
- To combine these two functions together, add MATCH as an argument inside INDEX.
- Press enter and marvel at the results!

These formulae are especially useful when working with large tables or complex datasets and eliminate the need for manual data manipulation.

It’s worth noting that while **VLOOKUP** is a common method used for similar purposes, INDEX-MATCH offers more flexibility and can be faster for larger datasets.

In practice, INDEX-MATCH was first introduced by Microsoft as a workaround solution when limitations were discovered with VLOOKUP. It has since become an essential tool for many experienced Excel users seeking more advanced functionalities.

### Macros

The concept of automating repetitive tasks in Excel is commonly known as **‘Automated Routines’**. For this purpose, Excel has an amazing feature named **‘VBScript-enabled Macros’**. These Macros can not only save time but also reduce the risk of errors that might happen due to manual data entry.

Function | Description | Example |
---|---|---|

Create Macro | A macro is a set of instructions that are saved and used to automate repeatable tasks. Macros can be created using the Macros recording tool. | Recording a Macro to bold all headings in an excel sheet. |

Edit Macro | A macro can be edited by going into the VBA editor and modifying the source code. | Changing the color from blue to green for selected cells contained within a macro. |

It’s important to remember that macros should only be used when it’s safe to do so. **Avoid running macros from untrusted sources, as they may contain malicious code.**

Interestingly, Macros were first introduced in version 2.x of Microsoft Excel for Macintosh in 1985. It was developed by **Charles Simonyi** and **Richard Brodie**, who both worked at Microsoft at the time.

*Why hire a financial analyst when you can just use Excel’s financial functions? It’s cheaper and won’t ask for a raise.*

### Financial functions

**Excel’s set of functions that deal with financial calculations are an unquestionable asset for businesses and individuals alike**. They enable users to take important financial decisions, extract insights from data, and simplify complex financial analysis. These functions encompass a range of activities, including calculating returns on investments, estimating interest rates, determining loan payments among others.

One of the most useful Financial Functions in Excel is LOG(Logarithm). **The LOG function** helps to calculate logarithms (the power to which a base is raised to produce a given number) relative to different bases in Excel worksheets. For example, it can help you calculate compounding interest rate over time or the amount of time required for an investment to grow at a certain rate.

Apart from its core usage in finance and accounting fields, the **LOG function** also has its application in engineering principles like information theory, vehicle-engineering logs and radio frequency calculation.

**Pro Tip:** Use shortcuts while using LOG Formulae by *pressing Shift+F3 on your keyboard*. This will bring up the Insert Function dialog box which will help you break down each argument used within the formulae for your ease!
