How to Change Bin Width in Excel on MAC

Excel is a powerful tool for data analysis, and one of its key features is creating histograms to visualize data distributions. When working with histograms, adjusting the bin width is crucial for accurately representing your data. This guide will walk you through the step-by-step process of how to change bin width in Excel on a Mac, ensuring you can effectively analyze and present your data.

Why Adjust Bin Width?

Before diving into the steps, it’s essential to understand why adjusting bin width matters. Bin width determines the size of each interval on the histogram’s x-axis. Choosing the right bin width can:

  1. Impact Interpretation:

Too wide bins may oversimplify the distribution, masking important details. Too narrow bins may obscure patterns, making interpretation challenging.

  1. Improve Visualization:

Optimal bin width ensures the histogram effectively communicates the shape and spread of your data distribution. By learning how to adjust bin width, you gain finer control over how your data is visualized, enhancing the insights you can derive from it.

Step-by-Step Guide to Change Bin Width in Excel on Mac

Follow these detailed steps to change the bin width in Excel on your Mac:

Step 1: Prepare Your Data

Ensure your data is organized in a single column in Excel. Each row should represent a data point you want to analyze.

Step 2: Insert a Histogram

  1. Select Your Data:

Click and drag to select the data range that you want to include in the histogram.

  1. Insert Histogram:

Go to the Data tab on the Excel ribbon. Find the Data Analysis tool (if not visible, you may need to enable it in Excel Preferences under Add-ins) and click on it.

  1. Choose Histogram:

In the Data Analysis dialog box, select Histogram and click OK.

Step 3: Configure Histogram Dialog Box

  1. Input Range:

Excel will prompt you to enter the input range. Ensure the range matches your data selection.

  1. Bin Range:

Specify the bin range. By default, Excel suggests a bin range based on your data, but you can adjust this manually.

Step 4: Adjust Bin Width

  1. Customize Bins:

In the Histogram dialog box, locate the Bin Width field.

  1. Set Bin Width:

Enter your desired bin width. Excel allows you to specify this directly, ensuring flexibility in how your data is grouped and displayed.

Step 5: Generate Histogram

  1. Output Options:

Choose where you want Excel to output the histogram (e.g., a new worksheet or existing worksheet).

  1. Click OK:

Once settings are configured, click OK. Excel will generate the histogram with the specified bin width.

Tips for Choosing Bin Width

Scott’s Rule:

A common heuristic for choosing bin width is Scott’s Rule, which suggests

Bin Width= 3.5×Standard Deviation/3√sample size


Adjust bin width iteratively to find the most informative histogram representation for your data.

Consider Data Characteristics:

Bin width should reflect the underlying distribution characteristics of your data (e.g., range, skewness).


  • Mastering the ability to change bin width in Excel on your Mac empowers you to create insightful histograms that effectively communicate your data’s distribution.
  • By following this guide on how to change bin width in excel on mac, you’ve learned not only the practical steps but also the significance of bin width adjustment in data visualization. Excel’s flexibility ensures you can tailor histograms to meet specific analytical needs, enhancing your ability to derive meaningful insights from your data.
  • Whether you’re analyzing sales figures, survey responses, or scientific measurements, understanding and applying these techniques will elevate your data analysis capabilities in Excel on your Mac.
