How to Remove Duplicates in Excel for Students

As a writer, I understand that my role isn't just about forming sentences and synthesizing information—it often involves gathering and presenting data in a clear and understandable manner for my audience. I've encountered firsthand how problematic duplicates can be in Excel sheets, causing confusion and hindering data analysis. So, if you're a student grappling with Excel and eager to remove those pesky duplicates to streamline your work. I'm here to guide you through the process of how to remove duplicates in excel for students.

Removing Duplicates Resolves Data Difficulties for Students

For students working with data in Excel, removing duplicates is a crucial step in ensuring accurate analysis. Here's why:

• Data cleaning or organization:

Duplicates in data can distort the outcomes of analysis. For instance, in experiments, if there are repeated entries for a single reaction, it would inaccurately affect the calculated average. Eliminating duplicates ensures a more precise depiction of the data. Furthermore, Statistical tests rely on independent data points. Duplicates violate this independence and can lead to misleading results. By removing duplicates, students can perform statistical tests with confidence.

• Preparation for accurate reports:

Duplicates can make data sets messy and difficult to understand. By removing them, students can simplify the data, making it easier to analyze and interpret. This minimizes errors, as duplicates can lead to inaccuracies in calculations and data analysis. Moreover, it aids in creating clearer and more professional reports.

• Increase data sensitivity:

Removing duplicates saves time and effort. Students can focus on analyzing the actual data instead of dealing with redundant entries.  In academic settings, data may be sensitive. Removing duplicates helps ensure that each piece of data is counted only once, improving the integrity and accuracy of analysis.

How to Remove Duplicates in Excel

Students often search the internet to learn how to remove duplicates in Excel but often end up more confused than before. Highlighting, removing, or working with duplicate entries each have their own specific methods that need to be addressed correctly. To help students find a more organized solution for removing duplicates in Excel, I've put together this tutorial. To make things easier, I'll be using WPS Office, a cost-effective alternative that offers all the functionalities of Excel with zero learning curve. So, let's switch tabs and dive into how to delete duplicates in Excel.

Highlight Duplicates

First of all, we will learn how to highlight duplicate entries in an Excel spreadsheet, a key step to identify whether our data contains any repetitive entries.

So, I'll be using a sample spreadsheet that contains a few experiment results, but due to some data entry issues, a few entries were repeated. To sort things out, I'll be using the "Highlight Duplicate Entries" feature in WPS Spreadsheet to get a quick glimpse of my errors.

Step 1: First, let's load our data into WPS Spreadsheet.

Step 2: Next, we will select the cells in which we wish to highlight the duplicate entries using our mouse.

Step 3: Now, head over to the Data tab in the toolbar and click on "Highlight Duplicates".

Step 4: In the Highlight Duplicates drop-down menu, click on the "Set" option.

Step 5: This will open the Highlight Duplicates dialog. Here, the range will be the cells selected in the second step. If you wish to change the range, you can do so here and then click "OK".

Step 6: All the duplicate cells will now be highlighted with an orange color.

This method allows students to easily identify any duplicate entries in their data using WPS Spreadsheet.

Remove Duplicates

Once you have highlighted data entry errors, which are quite common as you're focused on your work, you can easily fix the data entries by simply removing duplicates in Excel.

Step 1: Open the experiment results data spreadsheet where you have previously highlighted duplicate entries.

Step 2: Select the range of cells that you want to check for duplicates.

Step 3: Go to the "Data" tab in the toolbar and expand the options by clicking on the "Highlight Duplicates" button.

Step 4: Select the "Remove Duplicates" option from the drop-down menu.

Step 5: In the Remove Duplicates window, you can choose which columns to consider by selecting or deselecting them. The window also shows the number of duplicates found in the chosen columns.

Step 6: Once your selections are made, click "Remove Duplicates".

Step 7: WPS Spreadsheet will notify the number of duplicate entries removed from the data as well as the unique entries remaining, press “OK”.

WPS Spreadsheet streamlines duplicate handling effortlessly, making it my preferred office suite; its efficiency is particularly advantageous for students.

Use formula

Here's how students can utilize the UNIQUE function to eliminate duplicates in an Excel spreadsheet.

Step 1: Open your WPS Spreadsheet that contains the dataset with duplicate student entries.

Step 2: Choose an empty cell where you wish to apply the UNIQUE function.

Step 3: Initiate the function by typing an equals sign (=), followed by UNIQUE.

Step 4: Once the UNIQUE function appears in the suggestions, click on it and hit the Tab key to select it.

Step 5: The UNIQUE function requires only one parameter, the Array; highlight the entire range of data you wish to deduplicate and press Enter.

Step 6: A fresh table will be generated without any duplicate entries, ready for you to conduct additional data analysis or manipulation.
