Excel Skills Simplified: Tutorials That Actually Work
Creating a heat map in Excel is a great way to visually represent data by color-coding values, making it easier to understand patterns, trends, and outliers in a dataset. Here’s how you can create a heat map using Excel’s Conditional Formatting feature:
The “Runtime Error 9: Subscript out of range” error in Excel occurs when your Visual Basic for Applications (VBA) code attempts to reference a workbook, worksheet, or other object that doesn’t exist or isn’t available.
This error can be caused by various reasons but often results from referencing an incorrect workbook or sheet name in your VBA code.
ByVal is more than just a keyword in VBA. It’s a powerful tool that can help you write clean, efficient, and bug-free code. We’ll explain what ByVal means, why it’s important, and how to use it correctly.
Turnaround time (TAT) refers to the total time it takes to complete a task or process, from start to finish. In the context of Excel, calculating TAT involves determining the difference between two dates and times in order to determine the duration of an event or process.
An S-curve, also known as an S-shaped curve or sigmoid curve, is a graphical representation of data that exhibits a characteristic “S” shape. It is commonly used in project management, sales forecasting, and various other fields to visualize the growth or progression of data over time.
In this article, we’ll explore the steps to create an S-curve in Excel.
Performing a Tukey test in Excel can be done using the built-in Data Analysis ToolPak add-in, which provides a range of statistical analysis tools. The Tukey test, also known as the Tukey-Kramer test or Tukey’s Honestly Significant Difference (HSD) test, is commonly used for post hoc analysis following an analysis of variance (ANOVA) when you have three or more groups to compare. It helps identify which group(s) differ significantly from others. Here’s how you can perform a Tukey test in Excel:
Division in Excel is as simple as using the forward slash operator. Type =10/2 and Excel returns 5. Type =A1/B1 and Excel divides whatever is in A1 by whatever is in B1. The basic operation is straightforward, but understanding how to use division effectively across spreadsheets, handle errors gracefully, and format results properly transforms division from a simple calculation
into a powerful analytical tool.
Division appears constantly in spreadsheet work. You divide total expenses by number of months to get average monthly spending. You divide revenue by number of units sold to get revenue per unit. You divide budgeted amount by actual amount to calculate the percentage of budget used. You divide total sales by number of salespeople to get average sales per person. These practical calculations drive business decisions. Getting division right matters.
The challenge with division is that it can fail. Dividing by zero produces an error. Dividing cells containing text produces an error. Dividing very large numbers by very small numbers can produce unexpected results. Understanding these edge cases and how to handle them prevents errors and builds confidence in your formulas.
Performing polynomial regression in Excel involves fitting a polynomial equation to a set of data points. Unlike linear regression, which is straight-line fitting, polynomial regression fits a curve, making it suitable for more complex relationships between variables. Here’s how you can perform polynomial regression in Excel:
Calculating the Net Present Value (NPV) in Excel is a common financial analysis task. NPV measures the profitability of an investment by discounting all expected future cash flows to their present value.
Here’s how to calculate NPV in Excel:
Quadratic equations are a common mathematical problem, and you can efficiently solve them using Microsoft Excel. Here’s a systematic approach to finding the solutions to a quadratic equation in Excel:
