# boxhist2: Univariate Exploration of a CSV File (Flexible Formatting)

Exercise template with more flexible formatting for assessing the interpretation of exploratory statistics (quantiles) and graphics (boxplot and histogram) based on a randomly-generated CSV file.

**Name:**

`boxhist2`

**Type:**

**Related:**

**Description:**

Univariate numeric data for download in a CSV file (comma-separated values) need to be assessed using quantiles (three numeric items) and exploratory graphics (three single-choice items). Data are drawn randomly from a suitable data-generating process so that the single-choice items are either about correct or clearly wrong. The six items are embedded into the exercise using "##ANSWERi##" tags for somewhat improved layout.

**Solution feedback:**

Yes

**Randomization:**

Random numbers, text blocks, and data file

**Mathematical notation:**

Yes

**Verbatim R input/output:**

No

**Images:**

Yes

**Other supplements:**

No

*(Note that the HTML output contains mathematical equations in MathML, rendered by MathJax using ‘mathjax = TRUE’. Instead it is also possible to use ‘converter = “pandoc-mathjax”’ so that LaTeX equations are rendered by MathJax directly.)*
