Designed as a educational equipment, it provides a tangible way for students to visualize complex mathematical concepts. As the yellow beads descend through the precision-aligned peg array, they roll randomly to the left or right, eventually collecting in the bottom slots. This physics teaching aid beautifully demonstrates how numerous separate random events spontaneously coverage into a normal distribution curve, known as the Gaussian distribution.\n\nConstructed with a sturdy metal frame and transparent acrylic, this apparatus is built to withstand frequent use in busy classrooms or science fairs. transparent viewing panel allows for unobstructed observation from all angles, making it an ideal centerpiece for group demonstrations. It is large enough for a whole class to see while remaining portable for easy storage. Whether you are a teacher looking to simplify probability concepts or a science enthusiast, this Statistical board offers a captivating and intuitive learning experience.\n\nTo use the device, simply invert the board to collect all beads in the V-shaped reservoir at the top. Secure the sliding plate, then flip back to the upright position. Once you pull the release plate, the beads will descend through the pegs, simulating the movement of gas molecules and showcasing the statistical regularity of random motion. It is a combination of scientific accuracy and engaging visual for any educational setting.\n\nOption: Metal","category":{"slug":"music","label":"Music & Luthier","google_path":"Arts & Entertainment > Hobbies & Creative Arts > Musical Instruments"},"product_category":"Arts & Entertainment > Hobbies & Creative Arts > Musical Instruments","brand":"SuntekStore","condition":"new","price":"80.79 USD","price_amount":"80.79","currency":"USD","price_valid_until":"2026-10-31","tax":"US sales tax calculated at checkout (prices exclude tax)","availability":"in_stock","inventory_quantity":20,"max_quantity_per_order":10,"shipping":"US:ALL:Standard Shipping:11-21:0.00 USD","delivery_days":{"min":11,"max":21,"unit":"calendar_days_from_order","handling_business_days_max":4},"estimated_delivery":{"if_ordered_on":"2026-10-01","earliest":"2026-10-12","latest":"2026-10-22"},"ships_to":["US"],"shipping_cost":"0.00 USD","return_window_days":30,"return_policy":{"window_days":30,"window_starts":"delivery","condition":"unused, in original packaging","return_shipping_paid_by":"customer (we pay if the item is damaged, defective or not as described)","refund_method":"original payment method","refund_within_business_days_of_receipt":5,"how":"https://suntekstore.com/contact/ with the order number","url":"https://suntekstore.com/returns/"},"package_dimensions_cm":[43.0,33.0,6.0],"weight_g":2320.0,"material":"Metal, Acrylic","package_includes":"Dalton Board ×1","product_dimensions_cm":[4.0,30.5,41.5],"specifications":[{"name":"Color","value":"Black Frame with Yellow Beads"},{"name":"Model Number","value":"22220"},{"name":"Application","value":"Physics and Mathematics Teaching"},{"name":"Features","value":"V-shaped Reservoir, Precision Peg Array, Slot Dividers"}],"image_link":"https://suntekstore-img.sfo3.digitaloceanspaces.com/p/1d/1d4b752ad9f02774c7dd612e13c1cb823d409e31.jpg","additional_image_link":["https://suntekstore-img.sfo3.digitaloceanspaces.com/p/52/5271d764fcf286a451ea925c8b4251311a23e6cd.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/3c/3c3e6a63338c6c23f9632ec5bb01ecb0b208c94f.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/66/6608382927be5f3e5a19c59f012a88c1938e4d04.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/4b/4b45a3f6c4905812b09f6b1e703fbf25afa98173.jpg"],"thumbnail_link":null,"link":"https://suntekstore.com/p/DCD-10001076584/","markdown_url":"https://suntekstore.com/p/DCD-10001076584.md","json_url":"https://suntekstore.com/products/DCD-10001076584.json","buy_url":"https://suntekstore.com/buy/DCD-10001076584?qty=1","prop65_warning":null}
