Here is how to determine the first quartile (Q1) from the Boxplot 1 data in Excel and present it to three decimal places.

First, identify the data range that contains the numerical values from Boxplot 1. This is the set of values you will feed into the Excel function. If you have the data in a worksheet, the range would look like A2:A20 or similar, depending on where your data rows are located.

Next, apply the appropriate Excel function to obtain Q1. The standard choice in many Excel versions is QUARTILE.INC(range, 1). The 'range' should be replaced with your actual data range, and the 1 signifies the first quartile (25th percentile). For example, =QUARTILE.INC(A2:A20, 1).

Alternative method: you can use thePercentile function to get the same result, specifically =PERCENTILE.INC(range, 0.25). This returns the 25th percentile as well.

If you need the result rounded to three decimal places, wrap the function with ROUND. For example, =ROUND(QUARTILE.INC(A2:A20, 1), 3) or =ROUND(PERCENTILE.INC(A2:A20, 0.25), 3).

Important notes:
- QUARTILE.INC is commonly used and aligns with the inclusive method for quartiles, whereas there is also QUARTILE.EXC which uses exclusive calculation; they can yield different values for small datasets.
- If you are using an older version of Excel that lacks QUARTILE.INC, you can use =PERCENTILE(range, 0.25) or =QUARTILE(range, 1) depending on the version, but the newer recommended approach is QUARTILE.INC with a 0.25 equivalent via ROUND as needed.

In summary, to compute Q1 from Boxplot 1 data to three decimal places, you typically enter something like =ROUND(QUARTILE.INC(range, 1), 3) where 'range' is the actual data range you are analyzing.
