# How To Find Q1 In Excel

Discovering quartiles in datasets is essential for statistical analysis, and Excel offers tools to calculate these values efficiently. The first quartile, or Q1, represents the 25th percentile, separating the lowest 25% of data from the rest.

This guide will provide you with step-by-step instructions to find Q1 in Excel, utilizing built-in functions and formulas. We'll also explain how Sourcetable can simplify this process, offering a more user-friendly experience for calculating quartiles than Excel.

## Finding Q1 in Excel

### Using QUARTILE Function

To locate the first quartile (Q1) in Excel, use the QUARTILE function. Input your data set range as the first argument and use 1 for the second argument to specify Q1. The function will return the value at the 25th percentile.

### Transition to QUARTILE.INC and QUARTILE.EXC

Note that QUARTILE may not be supported in future Excel versions. Instead, use QUARTILE.INC or QUARTILE.EXC for more accurate results. For Q1, use either function with the data set range and 1 as arguments.

### Error Handling

Ensure your data array is not empty to avoid the #NUM! error. The 'quart' argument must be an integer between 0 and 4. For Q1, this argument should be 1.

### Alternative Functions

If QUARTILE is unavailable, the MIN function can provide the minimum value, MEDIAN can provide the second quartile (Q2), and MAX can provide the fourth quartile (Q4). However, to find Q1, use QUARTILE.INC or QUARTILE.EXC with 1 as the quart argument.

## Common Use Cases

• Determining the first quartile of a sales dataset to analyze distribution

• Assessing the lower 25% threshold for test scores in a classroom

• Identifying the lower quartile of temperatures collected in a climate study

• Evaluating the first quartile in a set of time-to-completion data for project management

## Excel vs. Sourcetable: Data Management and AI Assistance

Excel, a long-standing leader in spreadsheet software, offers robust data organization and calculation tools. In comparison, Sourcetable specializes in aggregating data from multiple sources into a single, query-friendly interface.

Unlike Excel, Sourcetable provides an AI copilot designed to streamline the creation of formulas and templates. This feature simplifies complex tasks through an intuitive chat interface, enhancing user productivity.

Sourcetable's AI assistance is a game-changer for those looking to accelerate data manipulation without deep technical expertise, a contrast to Excel's more manual approach.
