The add_boxplot() function requires one numeric variable, and guarantees boxplots are oriented correctly, regardless of whether the numeric variable is placed on the x or y scale. You can use backticks for inline code (`text` becomes text), or select a chunk of text and use the highlighted button to format it as a code block. Based on the output, we can see that the only significant difference is between technique 1 and technique 3.
