Here I will use the final version that has 52 stanzas. Yes, this is a long poem, but as one of its most famous lines states, \u201cI am large, I contain multitudes.\u201d There are many different ways to recombine these lines to create new poems. And hey, if we don\u2019t have time to read the whole poem, maybe we can still get a good sense of Whitman\u2019s style and message by looking at a sample of the full text. <\/p>\n<figure id=\"attachment_1869\" aria-describedby=\"caption-attachment-1869\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/mathvoices.ams.org\/featurecolumn\/wp-content\/uploads\/sites\/2\/2023\/12\/1860_LeavesOfGrass_Thayer_Eldridge_NYPL.jpeg?w=300&#038;ssl=1\" alt=\"Leaves of Grass 1860 frontispiece with calligraphic text\"  \/><figcaption id=\"caption-attachment-1869\" class=\"wp-caption-text\">Frontispiece to an 1860 edition of <em>Leaves of Grass<\/em><\/figcaption><\/figure>\n<p>The sampled poems created here are examples of <\/span><a href=\"https:\/\/poets.org\/glossary\/found-poem\"><span style=\"font-weight: 400\">found poetry<\/span><\/a><span style=\"font-weight: 400\"> that \u201ctake existing texts and refashion them, reorder them, and present them as poems.\u201d (There\u2019s even some <\/span><a href=\"https:\/\/sites.smith.edu\/ctrlwaltdelete\/pages\/\"><span style=\"font-weight: 400\">other found poetry based on Whitman<\/span><\/a><span style=\"font-weight: 400\">, this time via erasure poems, where poets choose what to erase from a pre-existing piece, rather than what to keep, like we do here.)

the dented sand,\r\nNot a youngster is taken for larceny but I go up too, and am tried and sentenced.\r\nI hear bravuras of birds, bustle of growing wheat, gossip of flames, clack of sticks cooking my

punctuation, this isn\u2019t too bad for a randomly-generated poem. There are some awkward transitions, but one could read this as the product of more of a stream of consciousness approach than the more meticulously revised original.<\/p>\n<h2>Stratified Random Sampling<\/h2>\n<p><span style=\"font-weight: 400\">But what if there are certain subgroups of the population that do not have many members? Since they are so rare, it will be hard to pick them as part of the sample, just by chance alone. Stratified random sampling allows us to split the population into groups and then sample members of each group to form our full sample. This way each group is represented in the final sample.<\/span><\/p>\n<p><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/mathvoices.ams.org\/featurecolumn\/wp-content\/uploads\/sites\/2\/2023\/12\/stratify.png?resize=300%2C300&#038;ssl=1\" alt=\"One dot randomly chosen from each row.\" width=\"300\" height=\"300\" class=\"aligncenter size-medium wp-image-1872\" srcset=\"https:\/\/i0.wp.com\/mathvoices.ams.org\/featurecolumn\/wp-content\/uploads\/sites\/2\/2023\/12\/stratify.png?resize=300%2C300&amp;ssl=1 300w, https:\/\/i0.wp.com\/mathvoices.ams.org\/featurecolumn\/wp-content\/uploads\/sites\/2\/2023\/12\/stratify.png?resize=150%2C150&amp;ssl=1 150w, https:\/\/i0.wp.com\/mathvoices.ams.org\/featurecolumn\/wp-content\/uploads\/sites\/2\/2023\/12\/stratify.png?resize=465%2C463&amp;ssl=1 465w, https:\/\/i0.wp.com\/mathvoices.ams.org\/featurecolumn\/wp-content\/uploads\/sites\/2\/2023\/12\/stratify.png?resize=502%2C500&amp;ssl=1 502w, https:\/\/i0.wp.com\/mathvoices.ams.org\/featurecolumn\/wp-content\/uploads\/sites\/2\/2023\/12\/stratify.png?w=550&amp;ssl=1 550w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p id=\"stratifiedReturn\">For example, there are some stanzas of Whitman\u2019s poem that have only 6 lines, where the median stanza length is about 20. If we stratify by stanza, so that each one is represented by one line, we end up with a poem like <a href=\"#stratified\">this<\/a>.<\/p>\n<p><span style=\"font-weight: 400\">This sampling approach lets every stanza have equal representation. We could also sample proportionally. That way each stanza is still represented, but longer stanzas aren\u2019t under-represented. That one gets a little long to print here, but check out the code to see an example and make your own.<\/span><\/p>\n<h2>Cluster Random Sampling<\/h2>\n<p id=\"clusterReturn\">Sometimes sampling comes with logistical challenges. For example, what if you had to travel to do the sampling? You might want to limit the number of cities you go to. You could cluster people by city and then sample at the city level, thereby limiting your travel. Here, we could cluster by stanza and pick a random sample of only stanzas for our new poem. This has the added benefit of keeping lines within a stanza together and limiting awkward transitions between lines.
