Hi there! I can definitely help you with performing a Tukey test for ANOVA post-hoc analysis in Excel.

Organizing the Data
Your data should be in columns, with each column representing a different group or treatment. The rows should contain the individual data points for each group. Make sure that your data is properly labeled and formatted.

Calculating the ANOVA
To calculate the ANOVA for your data, select the range of data that you want to analyze, go to the "Data" tab, and click on "Data Analysis" in the "Analysis" group. Select "ANOVA: Single Factor" from the list of analysis tools and click "OK". Follow the prompts to input your data and run the analysis.

Performing the Tukey Test
To perform the Tukey test for post-hoc analysis, you can use a free add-in called "Real Statistics Resource Pack".

To use the Real Statistics Resource Pack, you will need to download and install it. Once installed, you can access the Tukey test function by going to the "Real Statistics" tab in Excel and selecting "ANOVA" from the list of functions. From there, select "Post-hoc Tests" and then "Tukey's HSD". Follow the prompts to input your data and run the analysis.
